Abstract

The effect of the ratio of EPS bead radius to the specimen size (r/a) on the compressive strength is investigated by theoretical deduction. The results show that r/a, as well as volume fraction, plays an important role in affecting the compressive strength. The volume fraction of EPS beads determines the minimum compressive strength of EPS concrete specimen, the higher volume fraction, the lower the minimum compressive strength. The maximum compressive strength is relied on r/a. When r/a is smaller than 0.05, the effect of r/a can be neglected. As the EPS volume fraction increases, the maximum and the minimum compressive strength will be affected by changing r/a. Therefore, reducing the density and enhancing the compressive strength of EPS concrete can be accomplished by adjusting r/a value to a certain value under a certain volume fraction.
