EXPERIMENTAL INVESTIGATION ON LWC WITH COMPLETE REPLACEMENT OF COURSE AGGREGATE BY EPS BEADS
<p>In this paper, expanded polystyrene (EPS) lightweight concrete (LWC) was investigated. The mainaim was to design EPS LWC with the specified density of 1200 kg/m3 according to standard concretemix proportion. Mix proportion included total replacement of the conventional coarse aggregate bymaximum possible amount of EPS beads, which ensures concrete workability and prescribeddensity. The results demonstrated that exactly defined mixture-proportioning and casting procedureare required to achieve designed density. For designed EPS LWC mixture properties of freshlymixedconcrete and hardened concrete were analyzed. Based on test results it is concluded thatdesigned EPS LWC can be used for structural-insulating purpose such as floors and roofs.</p>
