Experimental Investigation on the Properties of Lightweight Concrete Containing Waste Oil Palm Shell Aggregate

This paper presents a study on the properties of a sustainable lightweight concrete incorporating high volume of waste materials. The concrete was produced utilizing lightweight oil palm shell (OPS), which is a waste material from the palm oil industry as well as manufactured sand, which is obtained from the processing of quarry waste, to replace conventional materials as coarse and fine aggregate in the concrete, respectively. In addition, ground granulated blast furnace slag (GGBS) was utilized at 20% cement replacement level to reduce the cement content in the OPS concrete (OPSC) as to further encourage the environmental- sustainability of the concrete. In the experimental study, selected properties such as the mechanical, permeation and structural properties of the OPSC were compared with those of conventional normal weight concrete (NWC) of equal targeted strength grade. While the performance of the mechanical properties such as splitting tensile strength and modulus of elasticity of the OPSC were inferior compared to NWC, the OPSC exhibited improved permeation properties such as the water absorption and sorptivity. The investigation of the structural properties such as the steel-concrete bond behavior as well as the flexural performance of reinforced concrete beam also demonstrated that the OPSC could behave similarly as NWC. The experimental results obtained in this study thus indicate the possibility of utilizing such concrete as a viable alternative for conventional NWC for practical applications. © 2015 The Authors.

Experimental Investigation of Properties of Concrete Containing Recycled Construction Wastes

Experimental Investigation of Properties of Concrete Containing Recycled Construction Wastes

This research focused on investigating the effects of recycled aggregates on the material properties of concrete and the structural performance of reinforced concrete beams. Two different sources of recycled aggregates, crushed red bricks and demolished concrete, collected from local construction and demolition wastes, were analysed. The pre-wetting method was applied to recycled coarse aggregates aiming to study its effects on concrete specimens. Experimental results assisted by regression analysis revealed that the pre-wetting method could minimize the negative effects caused by recycled aggregate itself on the concrete slump and compressive strength test results. Pre-wetting method was also found improving the dynamic modulus of elasticity for concrete specimens. Adding supplementary cementitious materials was not as effective as the pre-wetting method in enhancing concrete slump, Ultrasonic Pulse Velocity (UPV), strength, or dynamic modulus of elasticity. The reduction of concrete UPV and compressive strength caused by recycled aggregates were more significant in the early curing age. Flexural tests on reinforced concrete beams indicated that although adding recycled concrete aggregates did not significantly change the beam failure load, the ultimate deformation of reinforced concrete beams was reduced by displaying more brittle failure behavior. It was indicated that the failure mode of beam was changed from flexural to shear, inferring that shear capacity of beam with RCA was reduced. Future research directions were proposed focusing on the durability studies of concrete members containing recycled aggregates especially when the pre-wetting method was applied.

Experimental Investigation on Concrete with Replacement of Coconut Shell as a Fine Aggregate

ABSTRACT: The economy of the structure is affected by high cost of conventional construction material. With increasing concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the self-load of a structure and permit larger precast units to be handled. Recently in the environmental issues, restrictions of local and natural access or sources and disposal of waste material are gaining great importance. Today, it becomes more difficult to find a natural resource. Use of the waste materials not only helps in getting them utilized in cement, concrete and other construction materials, but also has numerous indirect benefits such as reduction in land fill cost, saving in energy, and protecting environment from possible pollution effect. It also helps in reducing the cost of concrete manufacturing. In the present work, coconut shell as partial replacement for coarse aggregate in concrete is studied. The concrete with ground coconut shell was found to be durable in terms of its resistance in water, acidic, alkaline and salty. Density of coconut shell is in the range of 550 - 650 kg/m3 and these are within the specified limits for lightweight aggregate. The characteristic properties of concrete such as compressive strength, flexural strength, impact resistance, bond strength & split tensile strength using the mix made by replacing coarse aggregate with crushed coconut shell aggregate were reviewed in the present work.

Experimental Investigation of Lime Treated Palm Kernel Shell and Sugarcane Bagasse Ash as Partial Replacement of Coarse Aggregate and Cement Respectively in Concrete

The tensile strength of concrete is one of the basic and important properties which greatly affect the extent and size of cracking in structures. Concrete de- velops cracks when tensile forces exceed its tensile strength. A tensile strength is a measure of the ability of material to resist a force that tends to pull it apart. It is expressed as the minimum tensile stress (force per unit area) needed to split the material apart. As portrayed in Figure 17 & Figure 18 the evolution of splitting tensile strength, the experimental results show a trend that resembles the com- pressive strength results. The Splitting tensile strength of lime treated PKS con- crete and SCBA concrete decreased as increased in percentage replacement while increased in curing age. This reduction can be attributed to poor compaction, increased surface area of the lime treated PKS, reduced bonding properties of SCBA in constituent materials in concrete as compared to the cement. This is in concordance with result reported by [15].

Compressive strength, flexural strength and water absorption of concrete containing palm oil kernel shell

Another reason for this study is the suitability and effectiveness of PKS and POF which act as a construction material for concrete production. Based on the previous research, PKS is used as lightweight aggregate to build a one-storey building and a foot bridge which is being monitored for their structural behaviour [2]. While for the POF, it is considered as natural fibre which can behave like reinforcement as well as improve the mechanical properties of concrete composite [5]. Hence, this study more concentrates on the comparison of conventional concrete, PKS concrete and PKS concrete containing with POF related with their workability, water absorption and strength as well as the performance of these two materials (PKS and POF) when subject to compressive and flexural strength test. In a nutshell, four series of concrete mix consists of 0%, 25%, 50% and 75% PKS is replaced by volume according to coarse aggregate content. Besides, the concrete is divided into two categories; PKS concrete mixed with and without POF. The use of 5cm length and 0.25% of the volume fraction of POF was conducted in this study.Formatting the title, authors and affiliations

materials more sustainable and convert it to a usable and reliable replacement for natural raw materials [2,3]. Using of the wastes for production of concrete is considered as a method to implement the waste management. Oil palm shell (OPS) is the common agricultural waste which could be used in concrete as aggregate to produce lightweight aggregate concrete. Advantages of the lightweight concrete in concrete structures encourage design engineers to employ this type of material for their design optimization. Due to reduction of the concrete weight, structural elements could be designed economically which leads to a significant saving in the cost of the supporting structures and foundation. With lighter concrete, for equal overall structural weight, it is possible to construct taller building or longer spans. The higher degree of thermal insulation of lightweight concrete also is considered as a remarkable advantage. The method for production of lightweight aggregate concrete by using of the OPS was introduced for the first time in Malaysia by Salam and Abdullah [4]. Several researchers have pointed out that conventional coarse aggregate can be replaced with OPS to produce structural grade of lightweight concrete [5,6]. Previous studies demonstrated that lightweight concrete by using of the OPS has satisfactory mechanical properties and durability performance. For oil palm shell concrete (OPSC), the compressive strength was reported in the range of 13-22 MPa. While with inclusion of cementitious materials and admixtures, compressive strength of 37 MPa has been obtained. Furthermore, lightweight concrete containing OPS and limestone powder, with compressive strength up to 48 MPa and density of about 1990 kg/m 3 has been reported [7-9].
