EXPERIMENTAL ANALYSIS OF SCRAP TYRE RUBBER AGGREGATES AND STEEL SCRAPS INFILLED BEAMS BY METHOD OF INITIAL FUNCTIONS

Abstract

Concrete is one the most extensively used construction material all over the world. Many scientists and researchers are in quest for developing alternate construction material that are environment friendly and contribute towards sustainable development. Huge amount of rubber tyre waste is generating day by day which creates the disposal problem and has many environmental issues. As this scrap rubber waste is an elastic material having less specific gravity, energy absorbent material can be used as a replacement material for obtaining light weight concrete. In reinforced concrete beams, concrete is in compression on one side and in tension on another side of neutral axis. In conventional design of RCC structures the concrete on tension side is not considered in the analysis. It is wastage of concrete in tension zone. Hence, concrete in this zone can be replaced by some modified concrete in which the aggregates are replaced by some waste material. Due to this the aggregates can be saved and waste material can be recycle. The aim of this study is to replace the aggregates in less stress concrete zone below the neutral axis by waste material like scrap tyre rubber aggregates (STRA) and steel scrap (SS). Total twenty one beams of size 150 x 250 x 700 mm are casted by replacing 0%, 20%, 40% and 60% of coarse aggregates with scrap tyre rubber aggregates for one set and fine aggregates with steel scraps for another concrete specimens.
