A STUDY ON PROPERTIES OF CRUMB RUBBER CONCRETE BY DESTRUCTIVE AND NON-DESTRUCTIVE TESTING

Utilization of industrial waste products in concrete is gaining importance all around the world due to the rise of environmental consciousness. Rubber from worn out tyres is one such waste material thought of by the researchers. Recycled rubber aggregates produce more elastic concrete, which has higher resistance to specific loads (impact loads, vibration and cyclic loads) compared to conventional concrete. Therefore, in this paper, the effect of crumb rubber on properties of Ordinary Portland Cement (OPC) Concrete and Ternary Blended Cement (TBC) Concrete of M40 grade are investigated with fly ash and silica fume as powders along with cement. TBC concrete has shown high energy absorption and higher strengths compared to OPC concrete.
