预应力纤维增强水泥砼比起不加预应力的有着许优点。但是,由于基质的收缩,应力作用将减少。如果采用硫铝酸盐水泥,可以减少基质的收缩。文章介绍了二组关于硫铝酸盐水泥砼基本物理机械性能的实验,讨论了外加剂对砼性能的影响,并提出:外加剂的比例是制造纤维增强水泥板技术的重要参数。 Prestressed fiber reinforced cement concrete than without prestressed has the advantage. However, due to shrinkage of the matrix, the stress effect will be reduced. With sulphoaluminate cement, shrinkage of the matrix can be reduced. Two sets of experiments on the basic physical and mechanical properties of sulphoaluminate cement concrete are introduced. The effects of additives on the properties of concrete are discussed. The proportion of admixture is an important parameter for the manufacture of fiber reinforced cement board technology.
