Morphology and Composite Characteristics of Lightweight Concrete with Styrofoam Filling Materials

Abstract

Abstract Concrete is made which is a material commonly used for construction and structures in buildings, concrete has many advantages compared to other building materials. However, concrete has one weakness, namely the specific gravity is high enough so that the dead load on a structure becomes large. Several methods can be used to reduce the concrete density, including using lightweight aggregates. One method to make lightweight concrete is by adding Styrofoam waste materials. However, this specific weight reduction is not followed by the addition of concrete compressive strength, so that until now lightweight concrete using Styrofoam is only used for non-structural parts. For this purpose, it is made to find out how much the influence of Styrofoam as a substitute for coarse aggregate on Concrete with the additional percentage of Styrofoam by 0%, 15%, and 35%, and 50% of the weight of the Concrete mixture.
