Experimental Behaviour of Waste Rubber Replaced in Hollow Block

Abstract

Our environment is subjected to many hazards and pollutants which is expanding and polluting in a very serious manner. One such thing is disposal of non non-degradable waste on the environment. It has been stated that volume of polymeric wastes like rubber tyres and PET bottles [ Polyethylene Terephthalate] is rapidly increasing in recent times. Waste rubber tyres is one among the crucial environmental hazard due to rapid increase of automobile production, leading in accumulation of waste of used rubber tyres. They are recycled rarely and others are just land land-filled or stockpiled. For this reason, various efforts have been made to recognize the unrealized, application of rubber obtained from the waste tyres in civil engineering innovations. Interestingly, these rubber materials are made into pieces and are used as an aggregate replacement. By incorporating them as building material, it has an added benefit of saving the aggregates obtained naturally which are used in greater amounts for producing concrete, creating scarcity of aggregates. On this note, our study aims in usage of rubber tyres as partial aggregate replacement. This paper reviews the performance of the hollow block made by integrating the pieces of discarded rubber tyres as aggregate replacement in various proportions. A great number of projects are available on aggregate replacement by rubber in concretes, but this paper deals with the rubber replacement in hollow block. Thus, different percentage of replacement of rubber are casted and tested for its compressive strength after they are cured for 3 days,7 days and 28 days. The test results were recorded and analyzed when they are subjected to aggregate replacement by rubber. After series of examinations and discussions, their results are concluded.
