Abstract
This paper develops a novel rubberized ultra-lightweight cement composites (RULCC) incorporated with different amount of rubber particles and investigates the static and dynamic mechanical properties of the RULCC experimentally. This study shows that the rubber particles have significant effect on the compressive strength, stress-strain curve and failure mode of the RULCC. A volume replacement of fine aggregates with 10% and 20% rubber particles results in a reduction in static compressive strength and elastic modulu. The dynamic experiments show the RULCC is a strain-rate sensitive material and the dynamic stress-strain curves illustrate that the capcity of energy absorbtion of RULCC is better than the composites without rubber particles. The experimental and analytical studies are essential to better understand the fundamental dynamic behaviour of RULCC for its further applications.
