用明矾石膨胀水泥或UEA膨胀剂来配制高强混凝土,可以在混凝土中引入一定的化学预应力,起到补偿收缩作用,减小混凝土的收缩开裂,提高混凝土的抗拉强度和抗弯强度,充分发挥高强混凝土的潜在性能,为制备高强混凝土提供了又一条可行的技术途径。
The use of alumite expansion cement or UEA expansion agent to formulate high-strength concrete can introduce certain chemical pre-stresses into concrete to compensate shrinkage, reduce shrinkage and cracking of concrete, and increase the tensile strength and flexural strength of concrete. The potential performance of high-strength concrete has been used to provide another feasible technical approach for the preparation of high-strength concrete.
