Keywords: Plastic Coarse Aggregate, Compressive Strength, Concrete Density, Structural Lightweight Concrete, Plastic pearls


Concrete is the most widely used construction material worldwide, so it faces a shortage of natural raw materials, as well as, concrete has a high-density drawback  (about 2400 kg/m³). These problems can be overcome by looking for new artificial materials to replace natural construction materials. Therefore, In the present work, the replacement of well-graded plastic pearls as coarse aggregate in concrete was investigated. The compressive strength and density of four concrete mixes were examined, before and after exchanging the coarse aggregate partially (50%) and fully (100%) by plastic pearls. Test results revealed that both concrete density and concrete strength reduce due to natural coarse aggregate replacement by plastic pearls. It is concluded that concrete of compressive strength between (23.9-42.5) MPa and density in the range of (1766-2226) kg/m³ can be produced when plastic pearls are used as coarse aggregate. It is also concluded that the plastic pearls, can successfully replace the natural coarse aggregate in concrete for solving the deficiency problem of this material.
