Abstract

Lightweight concrete that can be casted using lightweight cement, ultra-light aggregates, hollow sealed spheres made of ceramic and glass, clay bubbles entrapping air, foam material like polystyrene and recycled materials concrete has extreme importance in the construction industry. The weight of the cubes has reduced approximately 22, 26, and 27% using 5, 10, and 15% adding polystyrene foam, respectively. For the 5 % added polystyrene foam, the compressive strengths of the 7, 14, and 28 days increased with 22, 7, and 6%, respectively. While for the 10 % of polystyrene enhanced the compressive strength value of the 28 days with 2.6%. Finally, the compressive strengths of the 15 % of polystyrene cubes were degraded with 29, 28, and 4 %, at 7, 14, and 28 days, respectively. Regarding the flexural tensile strength, the more the added polystyrene foam, the lower is the related tensile. the flexural tensile strengths, at 7, 14, and 28 days, reduced with 16, 17, and 6 %, respectively adding 5 % of polystyrene foam, reduced with 26, 28, and 16 %, respectively adding 10 %, and reduced with 41, 39, and 33 %, respectively when 15 % of polystyrene foam was used.
