There are evenly distributed open pores and closed pores Inside sample, evenly distributed closed pores not only reduce the Wa, but also increase the resistance to freezing and thawing.
Mixture proportions, flowability, crack propagation at early ages, strength, shrinkage, carbonation and the freezing and thawing resistance of flowing concrete with high flowability were investigated.

它还具有一个抗渗性的功能,让建筑物体的冻融性能得到良好的改善。
It also has the function of anti permeability, so that the freezing and thawing properties of building objects have been improved.
