MECHANICAL PROPERTIES OF CONCRETE WITH PARTIAL REPLACEMENT OF COARSE AGGREGATE WITH EXPANDED POLYSTYRENE (EPS) BEADS

Civil Engineering

Concrete is the most widely used construction material in civil engineering structures. It has an excellent resistant to water and can be formed into a variety of shapes and sizes. Nowadays, the concrete industry consumes enormous amount of concrete produced daily, even a small reduction in the use of raw materials in concrete mixtures will result in considerable benefit to the environment. It is with this intention, an investigation proposed to be conducted by using Expanded Polystyrene (EPS)beads of 10 mm size as replacement of natural aggregates by volume from 0% to 60% in multiple of 15% (N/EPS00, EPS15, EPS30, EPS45 and EPS60) in cement concrete. The fresh mechanical properties of concrete with and without inclusion of Expanded Polystyrene (EPS) beads were evaluated in terms of workability, unit weigh or dry density, compressive strength and splitting tensile strength. Also this properties was observed and compare with normal concrete of Expanded Polystyrene (EPS) beads grade M20. The workability of fresh concrete increases with increase in percentage of Expanded Polystyrene (EPS) beads whereas the harden properties like unit weight, compressive strength and splitting tensile strength decreases with increase in percentage Expanded Polystyrene (EPS) beads . the addition of Expanded Polystyrene (EPS) beads in concrete meets the criteria of light weight concrete
