Abstract
A new type of concrete expansion agent has been successfully developed for the first time in the world by utilizing an industrial waste residue-soda residue and an industrial wasteliquor. 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 are described in this article. The experimental results show that the new type of concrete expansion agent accords with the standard and its main mineral component is xCaO−ySO3−zAl2O3.
