High-performance concrete expansive agent
The invention relates to the technical field of concrete admixture, in particular to a high-performance concrete expansive agent. The high-performance concrete expansive agent is prepared from, by weight, 30-40 parts of calcium sulphoaluminate, 8-16 parts of sepiolite, 4-11 parts of teflon powder, 3-9 parts of pentaerythrite, 1-4 parts of benzenediol and 5-10 parts of glass fiber powder. Shrinkage compensating of the high-performance concrete expansive agent has long effectiveness, the high-performance concrete expansive agent can be adapted to strength development of concrete, has excellent high-cracking-resistance impermeability, avoids that because cracking-resistance impermeability of concrete is insufficient, accumulated water permeability is generated, and the concrete can not be used and has high performance, and all the properties of the concrete expansive agent are improved and include the capacity of cracking resistance and impermeability, concrete compression strength and concrete breaking strength.
