Abstract—In this paper we are dealing with the effect of
partial replacement of cement with glass powder, to know the characteristics of fine glass powder which is mixed with concrete and then we differentiate the properties of glass power with cement. Now a days we have a large number of waste glasses available. So, we can make use of these waste products in construction work. In this paper cement is replaced at 5%, 10%, 15%, 20%, 25%and 30% which helps in the observation of strength of glass powder. Different tests were conducted to know its effect these are workability test, flexural strength test, compressive strength test, split tensile strength test and absorption test. Cost analysis is also done in this paper.
Keywords— Glass Powder, Workability, Compressive strength, Flexural strength, Split tensile, Absorption.
I. INTRODUCTION
A normal increase in population growth has resulted the huge amount of raise in waste material. This amount of waste is in the form of both decaying and non-decaying materials. Decaying material can be decomposed easily, but non decaying material will remain as it is till this world exists. This non-decaying material contributes a lot in the main environmental concerns in this world are solid waste. The waste products that we use in concrete makes it only economical but helps a lot in non decaying problems. The act of salvaging of huge amount of waste product is one of the best choice for controlling this wastage problem. The less harm compound to environment is glass as its waste materials does not pollute the environment, but it can harm the humans as well as animals if not handled carefully and the main reason is that glass is not of friendly nature to environment because of its non-biodegradable nature. New technologies are always required in this field. As its name suggests the glass consists of several chemical compounds like soda lime silicate glass, alkaline-silicate glass and biro silicate glass. In today’s era, these glasses glass powder are being used in cement and aggregate mixture as mortar for civil work.
The study had shown that concrete made glass aggregate has better long term strength and better thermal insulation and the reason for its better strength thermal insulations is due to the use of the glass powder as its concrete glass water products comes mainly from the household and the industries in the form of weight and density.
II. MATERIAL USED
Glass Powder
As the word itself defines glass that means it is a transparent material which is produced by melting of materials such as silica, soda lime and CaCo3 at very high temperature, which is then cooled during its solidification without crystallization. The glass which is very much used in our daily life through various products such as bottles, vacuum tubes, glass-ware and Sheet glass etc. As the amount of waste glass is increasing day by day, so we have to decompose it in a proper manner, as glass is very much used in our society which has increased in to use it into growing use of these glass products.
Portland cement:it is the most commonly used in cement that is grade 43.Portland cement is there elementary constituent of cement mortar and plaster.

92 Coarse aggregate:
Course aggregate are formed by sand, gravel or crushed stones. They should be greater than 4.7 mm but not more than 37.5 mm in diameter. Here, we have maximum size of 20 mm and normal continuous grading. The sieve analysis of fine and coarse aggregate is confirmed to IS10262.
III. METHODOLOGY
Mix design:- is known as the selection of mix ingredients and their proportions required in a concrete mix. We Used M20 concrete mix.
Compression Test:-
It is that value of uniaxial compressive stress reached as the materials completely fails. The test used for finding out compressive strength is compressive strength test. This test determines the compressive strength of a material at different ages. The apparatus used for this test is universal testing machine.
Flexural Strength Test:-
Flexural strength is measured of tensile strength of concrete. It is determined by conducting the test on prism, by two points loading. This test is performed on beams or on slabs and is checked that how much it can resist failure in bending. This is expressed as modulus of rupture (mr) in psi (mPa).
Split Tensile strength Test:-
This test is performed on concrete to determine the tensile strength of concrete. Concrete is very weak in tension as its brittle nature and is not expected to resist direct tension. When tensile forces are applied to concrete, the concrete shows cracks. So this test shows,how much tension does a concrete bear before getting failure.
Workability Test:-
Workability is the measure of consistency of concrete. It may also be defined as with which ease we can
mix,transport,place and handle the concrete . workability is directly proportional to the water cement ratio. I,e if we increase the content of water ,concrete will become more workable and vice versa. The test through which workability can be measured
is slump cone test.
Absorption Test:-
This test is done to find out how much water hard concrete can absorb or how much porous hard concrete is . For this test, bring three concrete blocks already prepared and put them in water for 24 hours. Bring the blocks out from the water and put them on mesh wire so that water will wipe out from the concrete.
Cost analysis:-
The analysis is done when we are taking the cost of cement and the cost of glass powder into consideration. They have a cost difference but the presence of silica in glass powder can increase its strength as compared to cement.

V. CONCLUSION
After going through the results mentioned above we conclude that compressive strength, flexure strength & split tensile strength is gradually increasing to some extent with the increase in replacement percentage of glass powder till 15% & afterwards it falls down. So its better to use the glass powder upto 20% & not more than that because of decrease in strength below normal concrete (15% being best as far as strength is considered rather that overall economy).
Considering the cost analysis we found that the cost saving is also reasonable & due to usage of waste glass powder the percentage cost of cement is saved upto some extent & the cost continuously decreases.
While going through the Slump test, its worth noting that workability increases by adding glass powder.
As far as water absorption property is concerned it goes on decreasing with the increase in glass powder percentage.
From the environment point of view, the waste material which gives rise to disposal treatment & land, is saved due to usage of this waste material in construction projects.
