Abstract. The use of brick in construction is commonly used, especially in the construction of buildings and infrastructure. Various studies have been conducted to produce methods that can increase the strength of brick at the same time can reduce the cost of manufacturing bricks. In order to reduce cost of manufacturing, one of the solution applied was by using waste as part of bricks production materials. In this study, sugarcane bagasse (SuCaB) ash was used as a part of compressed earth brick (CEB) by replacing the quantity of cement for SuCaB ash. The study focused on the physical and mechanical properties of CEB containing SuCaB and the optimum percentage of SuCaB ash as partial cement replacement in CEB. There are 4 types of percentages used; 0%, 20%, 25% and 30% from cement content. All mixed use the same water content of 30% of cement content by weight and the ratio for cement: laterite soil used was 1: 6. A total of 72 specimen with size of 100mm x 50mm x 40mm was produced. The test conducted were Initial Rate Absorption Test (IRA), Density Test, Dimensions Test, Compression Test and Water Absorption Test. From the experimental results, the optimum SuCaB ash percentage as cement replacement in CEB was 20%. It recorded the highest compressive strength of 16.23 MPa at 28 days while for the Initial Rate Absorption test, it lies within the range specified. The density of CEB containing 20% of SuCaB shows slightly lower value where it decreased for about 0.4% from the control specimen. From this study, it can be concluded that waste materials such as sugarcane bagasse can be used as part of construction materials. However, further study needs to be conducted such as on the energy consumption, chemical properties and others to enhance the knowledge on this area before it can be applied into the brick production.
The aim of this paper is to examine the impact response of reinforced concrete (RC) beam with artificial aggregate concrete block infill (RCAI) through experimental study and to propose the innovations of lightweight reinforced concrete utilizing polyethylene (PE) waste materials as an artificial aggregate. The study consists of the determination of optimum percentage of PE waste material as coarse aggregate replacements in the concrete mix and dynamic testing where an approximately 100 kg of impact weight dropped onto several beam specimens. Four concrete cube mixes with 0, 3, 6 and 9 % PE aggregate for 14 and 28 days respectively were prepared and tested under compression tests. Meanwhile, eight beam specimens categorized as normal reinforced concrete (NRC), RCAI and beam specimen that consists 6 % polyethylene waste material as a coarse aggregate (RC6A) were prepared and tested under low velocity impact loads under 1. DOI 10.1007/978-981-287-290-6_60 691 specimens are studied in terms of crack patterns (shear and flexural), crushing beneath the impact region and residual displacement at the mid-span. As results, it is observed that the 6 % of PE waste material in the concrete mix influence the strength of concrete about 10 %. Based on the failure mode results, all the beams are failed under drop height of 1.54 m. In addition, it is found that the residual displacement of RCAI is significantly lower than those of NRC and RC6A.
