Abstract
This innovative study presents the manufacture of structural lightweight concrete (SLWC) with 100 % waste coarser tire rubber and sets an inaugurating move in identifying its durability properties. Two newly designed casting moulds were developed to enhance the strength and durability properties of rubberized concrete without any conventional coarse aggregates. Slump values of different fresh RuC mixes varied from 84 to 122 mm, maintaining the requirement denoted by ACI 213R. Density and compressive strength of novel SLWC were determined. The durability properties, including water absorption, sorptivity, shrinkage, sulfate attack and rapid chloride penetration, were evaluated at 28-, 56-, 90-, and 180-day.
