Contribution of fibres to the properties of EPS lightweight concrete Available to Purchase

The effect of different fibres on the workability, mechanical properties, drying shrinkage and water adsorption was investigated on expanded polystyrene (EPS) lightweight concrete of high strength and workability. The results showed that the addition of fibres to the EPS lightweight concrete mixture during mixing substantially reduced the sedimentation of EPS beads and improved the uniformity of the mix as well. Compared with normal EPS concrete, fibres were demonstrated to have greatly increased strength, especially splitting tensile strength. It was also demonstrated that fibres restrained the long-term drying shrinkage. However, no significant effect was found of fibres on the water adsorption of EPS concrete.
