EXPERIMENTAL INVESTIGATION ON LWC WITH COMPLETE REPLACEMENT OF COURSE AGGREGATE BY EPS BEADS

In this paper, expanded polystyrene (EPS) lightweight concrete (LWC) was investigated. The main aim was to design EPS LWC with the specified density of 1200 kg/m3 according to standard concrete mix proportion. Mix roportion included total replacement of the conventional coarse aggregate by maximum possible amount of EPS beads, which ensures concrete workability and prescribed density. The results emonstrated that exactly defined mixture-proportioning and casting procedure are required to achieve designed density. For designed EPS LWC mixture properties of freshlymixed concrete and hardened concrete were analyzed. Based on test results it is concluded that designed EPS LWC can be used for structural-insulating purpose such as floors and roofs.
