ABSTRACT
This paper aims to study the possibility of obtaining lightweight concrete by using Expanded Polystyrene (EPS) beads instead of the natural aggregates (NA) in concrete mixes. Different replacement percentages of both coarse and fine aggregates were considered in three trials. Trial one consisted of seven replacement percentages: (1) 25% of coarse aggregates; (2) 50% of coarse aggregates; (3) 25% of fine aggregates; (4) 50% of fine aggregates; (5) 12.5% of both coarse and fine aggregates; (6) 25% of both coarse and fine aggregates; and (7) 50% of both coarse and fine aggregates. Trial two consisted of three replacement percentages: (1) 25% of coarse aggregates; (2) 50% of fine aggregates; and (3) 12.5% coarse + 25% fine aggregates. For trial three, seven concrete mixes were considered as follows: (1) Control mix; (2) 5% Silica Fume; (3) 10% Silica Fume; (4) 12.5% Coarse +25% Fine; (5) 12.5% Coarse +25% Fine + 5% Silica Fume; (6) 12.5% Coarse +25% Fine + 10% Silica Fume; and (7) 12.5% Coarse +25% Fine + 250ml Master Glenium 51 superplasticizer. A control mix for each trial was prepared for comparison purposes. Standard cubes and cylinders were tested at 7- and 28-days of casting to obtain the density and compressive strength of the concrete mixes. The results showed that the density and compressive strength of the concrete decreased when the EPS replacement levels increased, and the higher replacement levels of coarse aggregate had a very negative effect on the compressive strength. Thus, the certain levels of replacements of fine aggregate with coarse aggregate obtained better results. The optimum results were obtained for 12.5% Coarse +25% Fine + 250ml Master Glenium 51 superplasticizer mix where the density and compressive strength were reduced by 11.3% and 7.8%, respectively. The experimental results showed clearly that using EPS in concrete mixes is a promising approach to reduce the weight of concrete and provide compressive strength of concrete almost the same as NA concrete mixes.
