Deformation Properties of Concrete with Rubber Waste Additives
Keywords:
Portland cement concrete, rubber waste additive, compressive strength, deformation properties, modulus of elasticity, dynamic modulus of elasticity, cyclic load, strain, stress-strain diagram.Abstract
The aim of investigation was to study the deformation properties of Portland cement concrete with rubber waste
additive. Concrete mixtures with the same compressive strength as concrete without this additive were tested. Used tires
rubber wastes were crumbed into fraction 0/1. The rubber additive was used as fine aggregate replacement in concrete
mixtures by 3.2 % of aggregates mass. The effect of rubber waste additive on technological properties, air content in
fresh concrete, density and deformation properties under the static and dynamic load of concrete was investigated.
