Mechanical Propagates of Concrete with Partial Replacements of Sand by Plastic Waste of Vehicles under Impact Load

Abstract

Abstract:lastic waste of vehicle causes serious health and environmental problems all over the world. As a possible solution to the problem of plastic waste of vehicle, an experimental study was conducted to examine the potential of using it as sand replacement in the concrete. This paper examines impact strength properties of concrete in which different amounts 2.5%, 5%, 10% and 20 % of plastic waste particles were used as sand replacement. For each amount, six cubes of 100 mm ×100 mm × 100mm were subjected to 4.5 kg hammer from 480mm height. The number of blows of the hammer required to induce the first visible crack of the cubes were recorded. The results are presented in terms of impact energy required for the first visible crack. The concrete mixtures exhibited ability to absorb a large amount of impact energy. The plastic waste of vehicle increased the first crack impact energy of concrete.Keywords: Plastic waste of vehicle; Cement concrete; Compressive strength; Impact energy. I. INTRODUCTIONThe plastic waste of vehicle is considered as one of the major environmental problems faced by every country due to their health hazards and difficulty for land filling [1]. The reuse of wastes is important from different points of view. It helps to save and sustain natural resources that are not replenished, it decreases the pollution of the environment and it also helps to save and recycle energy production processes. Concrete has been identified to be one of the feasible options. Although concrete is the most commonly used construction material, it has limited properties such as low tensile strength, ductility, toughness and impact resistance [2].Substantial research was carried out on the application of polymers in concrete [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Batayeneh et al.[3] showed the deterioration of compressive strength with an increase in the proportion plastic content. For the plastic proportion of 20% of sand, the compressive strength was reduced up to 70% compared to that of normal concrete. Recently, Marzouk et al. [4] studied the use of consumed plastic bottle waste as sand substitution aggregate within composite materials for building applications and showed the effects of polyethylene terephthalate (PET) waste on the density and compressive strength of concrete. It was found that the density and compressive strength decreased when the PET aggregates exceeded 5% by volume of sand.Rahmani et al. [5], observed that the 5% replacement of fine aggregates with PET particles yields better results in compression. However, with further increase in polyethylene terephthalate particles to 10% and 15% the compressive strength of concrete decreases due to weak cohesion between the texture and the PET particles. Araghi et al. [6] reported that the concrete containing plastic waste has better sulfuric acid attack resistance in industrial structures and sewer pipes. Raj et al. [7] investigated the strength and behavior plain and fiber reinforced polymer concrete beam column joints and the r...
