  • How to Make Lightweight Concrete Using Styrofoam | Hunker

    Lightweight concrete, also known as EPScrete (expanded polystyrene concrete), is a material widely used in the building of environmentally "green" homes. The substance is often made using small Styrofoam balls as a lightweight aggregate instead of the crushed stone that is used in regular concrete.
