The properties of sulfur rubber concrete (SRC)

Abstract

The mix designs and specimen preparation for the dry process and wet process of sulfur rubber concrete (SRC) were investigated. The compressive strength, corrosion-resistance and toughness were studied and discussed. The results show that SRC is corrosionresistanct. Although the compressive strength of SRC decreases with increasing rubber content, the toughness increases instead. Adding micro-filler will improve the compressive strength of SRC. There is a threshold value for the sulfur content, at which the compressive strength and the workability of SRC reach an optimum balance. The bond between rubber particles and surrounding sulfur is strong due to the vulcanization process that generates cross-links through S-C bonds.
