Abstract
The foam bead concrete consists of foam beads (EPS particles), medium-coarse sand, macadam, cement, and water at a certain designed mix proportion through blending. All materials used in the tests are chosen and obtained nearby. The foam beads (EPS particles) are polystyrene spherical particles with a diameter of 3–5 mm and an apparent density of 5–20 kg/m3. The cement is ordinary Portland cement PO32.5. For the aggregate, the sand fineness modulus in the fine aggregate ranges from 3.0 to 2.3. The size distribution of macadam particles in the coarse aggregate ranges from 5 to 21.5 mm. The admixtures consist of common early-strength water-reducing agents, microsilica and fly ash.
