摘要
本文提出高强硅粉抗磨蚀混凝土开裂的成因有 :容易发生塑性收缩、早期干缩偏大、特别是自身体积收缩偏大三个主要原因。其防治措施为加强早期潮湿养护和加入补偿早期收缩的材料。文章的最后还介绍了工程实际应用情况。
? This paper indicates the three main reasons of the crack of high strength concrete combined silica fume used for abrasion and csvitaion resistance,they are higher mould shrinkage,early stage shrinkage and autogenous volume shrinkage The prevention methods of crack are strengthoning early stage curing curing and using and using expanding admixture,Finally,appllcations of this concrete in several projecis were introduced. 〔
