Abstract

A type of concrete expansion agent was developed by utilizing an industrial waste residue-soda residue and an industrial waste liquor. Adding 3%-6% of the agent into Portland cement enables a shrinkage-compensating concrete to be prepared. Mortar and concrete containing this expansion agent have better shrinkage-compensating and mechanical properties. The raw materials component, production process, technical properties, micro-analysis of mortar made with this expansion agent, mechanism of expansion and research results were described. The experimental results show that this type of concrete expansion agent accords with the standard and its main mineral component is xCaO-ySO3-zAl2O3.
