Hydration and Expansion Properties of Novel Concrete Expansive Agent

Abstract:

Article Preview

The hydration and expansive characterization of a novel concrete expansive agent were investigated in this paper. The results showed that the hydration activities of the novel agent depended on the calcining temperature, particle size and curing temperature. When the expansive agent was mixed in concrete, the early shrinkage of concrete was reduced. If the content and distribution of the expansive agent in concrete is appropriate and uniform, the expansion rate of concrete may be controlled, and the shrinkage of concrete could be compensated effectively by the gentle volume expansion.
