Lightweight concrete is a very useful building material used in the construction sector for providing better
insulation and lower energy consumption. Properties of lightweight aggregate, water-cement ratio, and other additives
strongly affect the concrete strength, thermal properties, and workability. This paper investigates the behavior of lightweight
concrete using rubber particles as fine aggregate, replaced by the expanded glass lightweight aggregate in the
concrete mixture. In the concrete mixture expanded glass aggregate is replaced by rubber particles by 5%, 10%, 20%,
30%, 40%, and 50% by mass. Concrete workability, density, compressive strength, flexural strength, water absorption
tests were examined. Workability and density were increasing by increasing rubber particles replacement percentages
in the concrete mixture. On the other hand, compressive strength and flexural strength were decreasing by higher percentages
of rubber particles replacement. Strength properties of rubberized concrete can be balanced by the proper
utilization of binding materials in the concrete. Rubberized concrete can be used in the construction sector efficiently as
partial replacement of lightweight aggregate in the concrete mixture.
