ABSTRACT: Cement is the third most energy intensive material after steel and aluminum produced in tones. Cement industry consumes raw materials rich in silica, alumina, iron and calcium. Therefore this industry has been actively involved in finding ways to use waste products in the manufacturing of cement both as secondary fuel and raw material. Since the demand in the concrete manufacturing is increasing day by day, the utilization of river sand as fine aggregate leads to exploitation of natural resources, lowering of water table, sinking of the bridge piers, etc. as a common treat. An attempt has been made in using crushed glass as fine aggregate in the replacement of river sand. The crushed glass was also used as coarse aggregate in concrete production but due to its flat and elongated nature which enhances the decrease in the workability and attributed the drop in compressive strength. The present scenario demands identification of substitute materials for the river sand for making concrete. Recently, some attempts have been made to use ground glass as a replacement in concrete. The objective of this project is to present the results of experimental investigations on Physical and Mechanical properties of concrete made with wasteGlasspowderconcrete. Natural fine aggregate, cement is substituted by weight by wasteGlassPowder at rates varying from 5,10,15,20 and 25 percentages. Compressive, Tension, are evaluated and compared up to 28 days of ages. Specific Properties of concrete materials and Sheet GlassPowder are also studied.
of GLP gives higher strength. And also GLP size less than 90 micron is very effective in enhancement of strength. Bajad M.N. et al  studied the strength properties containing glass when subjected to sulphate attack and showed that the peak compressive strength is achieved at 20% replacement of cement by wasteglasspowder both when concrete is not subjected to sulphate attack and when concrete subjected to sulphate attack and the increment continues upto 25% replacement beyond which it decreases. Gopalakrishnan Ramasamy and Govindaraja Dharshnamoorthy  carried out tests on wasteglass admixture cement and resulted that the compressive strength result is a confirmation of retarding effect of WG in the hydration of Portland cement. Wang Her-Yung and Hou Tsung-Chin  carried out their study of Elevated Temperatures on the Strength Properties of LCD GlassPowder Cement Mortars and concluded that substituting 10% of cement by glasspowder would gain a very promising compressive strength of the mortars, particularly when the added glass has a powder fineness ≥ 4500 cm2/g. In real practices, this amount of glasspowder substituent could be suggestively used to replace cement. Oliveira L.A Pereira de et al  study focused on the assessment of the pozzolanic activity of green, amber and flint color wasteglass of different particle sizes(75μm – 150μm,45μm – 75μm and < 4μm) as a component of cementitious materials used as filler or binder in mortar and concrete. He concluded that 30% of 45 - 75 μm ground waste glasses size range could be incorporated as cement replacement in mortar or concrete without any detrimental effects caused by the expansivity provoked by the alkali silica reaction. Shayan Ahmad  concluded that 30% GLP could be incorporated as cement or aggregate replacement in concrete without any long-term detrimental effects. Up to 50% of both fine and coarse aggregate could also be replaced in concrete of 32 MPa strength grade with acceptable strength development properties.
In present paper I am investigating the role and effects of Foundry Waste sand’s use in concrete to improve its strength & other durability factors. Also usages of wasteglasspowder as partial replacement of Portland cement. Replacing cement by pozolanic material like wasteglasspowder in concrete, reduces the workability. Therefore, the concrete containing wasteglasspowder (GP) needs to be investigated.

ABSTRACT: Concrete industry is one of the largest consumers of natural resources due to which sustainability of concrete industry is under threat. The environmental and economic concern is the biggest challenge concrete industry is facing. In this paper, suitability of use of wasteglasspowder as partial replacement of cement in fibre reinforced concrete is discussed so that issues concerned with environment will get some alternative. Cement was replaced by wasteglasspowder as 0% to 40% in increment of 5% in M30 mix. The concrete specimens were tested for compressive strength, splitting tensile strength, flexural strength at 7days, 28 days, 60days, 90days and 180days of age and the results obtained were compared with those of normal concrete. The results concluded the permissibility of using wasteglasspowder as partial replacement of cement at 20% by weight.
Veena V Bhatet. al., (2014) studied the use of wasteglass as a replacement material for ordinary Portland cement partially in concrete with 5%, 10%, 15% and 20 W P Prema Kumar et.al., (2014) [2 ] considered over that wasteglasspowder supplant the bond in M20 concrete in ventures of 5% from 0% to 40%..Jitendra B. Jangid (2014)  considered over the glasspowder incompletely supplanted at different rate between 0 to 40, at an interim of 5% . T Subramani and S B Sankar Ram (2015)  studied the property of concrete by partially replacing cement by glasspowder. 10%, 20%, 30% and 40% percentage of glasspowder Mohd Rahman et.al.,(2015)  studied replacing the cement by wasteglasspowder partially. Kishan Jain et.al. , (2016)  conducted a study on concrete by replacing cement by wasteglasspowder in the range of 5% to 20.
The optimum replacement of wasteglasspowder with cement in crushed aggregate and rounded aggregate is found to be 10% at which the compressive strength of cube at 7 days & 28 days are higher than those of concrete cube prepared with replacement of 5%, 15% & 20% and without replacement of wasteglasspowder with cement.Similarly replacement of Brick dust with sand in crushed aggregate is also found to be effective. The optimum replacement is found to be 5% at which the strength of cube at 7 days and 28 days are higher. The result obtained from testing the cubes with brick dust with rounded aggregate gives that the strength at 7 days with replacement of 10% Brick dust gives more strength but after 28
The potential for using fly ash as a supplementary cementing material in con- crete has been known almost since the beginning of the previous century. Fly ash was used as a supplementary cementing material (SCM) in the production of Portland cement concrete. A supplementary cementing material, when used in conjunction with Portland cement, contributes to the properties of the hardened concrete through hydraulic or pozzolanic activity, or both. In this study, the fly ash and wasteglasspowder were used in concrete blocks to study the improvement of concrete in terms of workability and strength. Therefore, an experimental study will be conducted to measure the engineer- ing properties of cured concrete. In this research, local raw material from Ja- resh area was used.
The glass is non-biodegradable material and it is not suitable for landfill although glass can be recycled and reused but the cost of recycled glass is more than that of the virgin glass. Glass is a general product that can be found in different types: bottles, jars, window, windshields, bulbs, and cathode ray tubes etc. These goods have a narrow lifetime and generally disposed of after its usage. Utilization of wasteglass has fascinated construction industry due to its feasible utilization in concrete. Use of wasteglass as aggregate in concrete has been attempted by many scientists. Fine aggregate was partially replaced with glasspowder at 10%,, 20%,30% and 40% by weight of the fine aggregate and tested for its compressive strength and flexural strength at7 days and 28 days was compared with conventional concrete. From the results obtained, it was found to be glasspowder can be effectively used as fine aggregate replacement. The recycling and reuse of the waste has become the best alternatives as their disposal problem of waste .The reuse of such waste will reduce the environment impact and is more economical the energy required to reuse the recyclable material is less than that of virgin materials. Use of natural aggregates at a great rate leads to a question about the preservation of natural aggregates sources. In addition, operation associated with aggregates extraction and processing is the principal causes environmental concern.
The results show the improved characteristics of the blended concrete in terms of compressive, tensile and flexural strength & durability parameters as well. Many try has been carried out to replace fine aggregate and coarse aggregate but the result does not satisfy the requirement. But for partial replacement in cement ratio it is observed to be satisfying the requirement. The approach is an integrated one in that it links durability index parameters, and performance specifications. The current study is concerned with the incorporation of glasspowder in concrete with different percentage and conducts workability test, compressive test, flexural test, and tensile test.
contains a few synthetic assorted varieties including soft drink lime silicate glass, alkali-silicate glass and boro-silicate glass. To date, these sorts of glasses glasspowder have been broadly utilized augmentation and aggregate blend as pozzolana for civil works. The presentation of wasteglass augmentation will build the alkali content in the cement. It additionally help in blocks and clay fabricate and it jelly crude materials, diminishes vitality utilization and volume of waste sent to landfill. As valuable reused materials, glasses and glasspowder are for the most part utilized in fields identified with civil engineering, for instance ,in cement, as pozzolana (strengthening cementitious materials),and coarse aggregate. Their reuse ingratiois near 100%, and it is alsousedin concrete without antagonistic impacts in concrete toughness.
In the present work cement is partially replaced by wasteglasspowder in different proportions (2%, 6%, 10%, 14%, 18%, 22%, 26% and 30%) by weight. The compressive strength of various concretes are compared and based on that comparison it is concluded that glasspowder of size less than 90 micron can be used as partial replacement of cement. Result shows that compressive strength as well as the flexural strength is maximum when 18% cement is partially replaced by wasteglasspowder by weight.
The main objective of this experimental study is to investigate the behavior of Recycled Reactive PowderConcrete (RRPC) developed from finely dispersed local waste raw materials. In this study, RRPC was developed by utilizing local wastes (finely dispersed wasteglasspowder, waste fly ash and waste ceramic powder) together with Portland cement, fine sand, admixture, steel fibers and water through full replacement of silica fume as well as quartz powder for sustainable construction practice. In this study, all raw materials for making RRPC were analyzed for X-Ray Fluorescence analysis. For sustainability of local construction works, this study employed standard curing method at am- bient temperatures instead of steam curing at higher temperatures. Moreover, hand mixing was used throughout the study. To evaluate the structural per- formances of the developed RRPC mixes, compressive and flexural strengths of RRPC were investigated experimentally and compared with the control mix. The experimental results indicated that replacing the silica fume fully by finely dispersed local wasteglasspowder (GP) and fly ash (FA) is a promising approach for local structural construction applications. Accordingly, a mean compressive strength of 62.9 MPa and flexural strength of 8.8 MPa were de- veloped using 50% GP-50% FA at 28 th days standard curing. In this study,
The present study on wasteglasspowder as a replacement of cement to assess the pozzolanic activity of fine glasspowder in concrete. A number of test were conducted on specimens to study the effect of 10% ,20% and 30% replacement of cement by wasteglasspowder. The compressive strength, split tensile strength and the flexural strength test were conducted for the mixes at the curing age of 7 days and 28 days. All the results of experiments were compared with the normal concrete mix’s results. Wasteglasspowder in partial replacement of cement in concrete can be prove beneficial to disposal problem of glasswaste and the need of economic raw material to the concrete industry.
Abstract The effects of partially replacing of cement with glasspowder in concrete were studied and therefore found that some extent could be replaced which contributes in strength development. Cement was partially replaced with glasspowder at varying percentages such as 10%, 20% and 30% and several concrete cylinders were casted along with plain concrete specimen. The cylinders were tested for compressive strength and split tensile strength at the age of 7, 14 and 28 days and were compared with the results of plain concrete. The overall test results indicated that the wasteglasspowder could be utilized in concrete as a good substitute of cement up to particle size less than 75μm. In replacement of cement with glasspowder of 10%, the compressive strength and split tensile strength were reduced in 7 th days for all

Abstract: - Concrete industry is one of the largest consumers of natural resources due to which sustainability of concrete industry is under threat. The environmental and economic concern is the biggest challenge concrete industry is facing. In this paper, the issues of environmental and economic concern are addressed by the use of wasteglass as partial replacement of fine aggregates in concrete. Fine aggregates were replaced by wasteglasspowder as 10%, 20%, 30% and 40% by weight for M-25 mix. The concrete specimens were tested for compressive strength, splitting tensile strength, durability (water absorption) and density at 28 days of age and the results obtained were compared with those of normal concrete. The results concluded the permissibility of using wasteglasspowder as partial replacement of fine aggregates up to 30% by weight for particle size of range 0-1.18mm.
This experiment shown the property of concrete containing wasteglasspowder as a fine aggregate replacement material. The use of waste or by product in concrete production has advantages for improving some or all of the concrete properties. The work is examines the effect of using of wasteglasspowder as cement and sand replacement material into a concrete.. Glass constitutes about 5% of the municipal solid waste stream but only a small percentage of it is recycled. Waste contains about 72.5% SiO 2 , when it is ground to the fineness of around
The use of recycled glass as aggregate greatly enhances the aesthetic appeal of the concrete. Recent research findings have shown that concrete made with recycled glass aggregate have shown better long term strength and better thermal insulation due to its better thermal properties of the glass aggregates(Samtur.H.R,1974, Seung Bum Park and Bong-Chum Lee,2004). When tested for the compressive strength values at the 10 %, 40%, and 60 % aggregate replacement by wasteglass with 0 – 10mm particle size were 3%, 8% and 5% above the value of conventional concrete. It has been concluded that 30% glasspowder could be incorporated as cement replacement in concrete without any long-term detrimental effects. Upto 50% of both fine and coarse aggregate could also be replaced in concrete of 32 MPa strength grade with acceptable strength development properties. Better results are achieved when the wasteglasspowder replaced either 30 % or 70% of the sand with particles sizes ranging between 50 µm and 100 µm (Federio.L.M and Chidiac S.E,2001). Used glasswaste, which is cylindrical in shape prevents crack propagation in concrete structures. From the research carried out on glasspowder by the authors, it was found that glass of particle size 1.18 to 2.36 mm produced the highest expansion where as low expansion was observed at smaller particle sizes(Idir.R,Cyr.M and Tagnit – Hamou.A,2009). It was observed that with a 30% replacement of cement by amber wasteglass content of particle size 75µm along with flyash, the compressive strength of concrete increase 25% at 7 days and 35% when tested for 28 days strength (Pereira de Oliveira. L.A, J.P. castro – Gomes, P. Santos, 2008). This effect provide ample evidence that both flyash and wasteglass sand can be used together to produce concretes with relative high strength without any adverse reaction. Particle sizes under that threshold had no effect on length variations. Glass was ground to a particle size of 300 or smaller, the alkali reaction (ASR) induced expansion could be reduced.
