AN EXPERIMENTAL LABORATORY STUDY ON UTILIZATION OF CERAMIC WASTE AS A PARTIAL REPLACEMENT OF COARSE AGGREGATE IN CONCRETE

Abstract

Reuse and recycled plastic materials in concrete mix as an environmentally friendly construction material has drawn attention of researchers in recent times, and a large number of studies reporting the behavior of concrete containing waste and recycled plastic materials have been published. In present study trash bags plastics are used as polymer wastes HDPE for preparation of Recycled Plastic Aggregates (RPA). The ambition of this work is to study the properties and behaviour of RPA in the concrete as a replacement to Natural Coarse Aggregate (NCA). The RPA are produced under a controlled temperature 160°C to 190°C and crushed to 20 mm downsize aggregates. Develop the M25 grade concrete as per IS 10262- 2019. Then partially replace the NCA by RPA by its weight (0,15%,20%, 25%, 30%, 35%, & 40%). The wide range parametric study was carried out to find the effects of RPA on the workability and strength of the concrete. The results shows that up to 15% of RPA is suitable for structural concrete and remaining is best for non-structural usage.
