IMPACT ON CONCRETE BY PARTIAL REPLACEMENT OF COARSE AGGREGATE WITH RECYCLED PLASTIC GRANULES

Abstract

How Low Density Polyethylene (LDPE) can be used as a replacement for coarse aggregate in order to produce concrete cubes and cylinders is being researched and thus reported in this paper. The concrete material prepared by this process was manually experimented and treated by the process of compression and split tension. It is found that the strength of the plastic replaced by concrete because of compression and split tension can be compared to the conventional concrete. In this paper the study is aimed at how LDPE (in some certain amount) can increase the tensile strength to the concrete produced in order to reduce the fragility of the material previously used. This mixture of cubes and cylinders was subjected to compression and split tension in order to ascertain the parameter of strength. Hence the use of treated plastic wastes in concrete is not only beneficial but also helpful in disposal of plastic wastes, thus reducing the environmental pollution to a large extent. The concrete thus developed, can increase the strength of structures and hence reducing the various environmental hazards.
