| 摘 要： | 在高强混凝土中掺入适量的硅灰,对提高混凝土的劈裂抗拉强度有非常明显的效果,也可在一定程度上增强混凝土的抗压强度和抗折强度.掺量低于或高于适量范围,对提高混凝土的强度作用很小.在实际工程混凝土中合理掺用硅灰,不仅可以提高混凝土的强度,而且变废为宝,改善环境,技术、经济和社会效益显著.

| Abstract: | It has obvious effect of mixing appropriate quantity of silica fume in high-strength concrete to enhance its splitting tensile strength,and could increase its compressive strength and flexural strength to a certain extent.However,it could be useless for strength enhancing if the mixing quantity is lower or higher than the appropriate quantity.Reasonable mixing silica fume in engineering concrete not only increase the strength but also recycle waste material and improve environment and technique which has re... |
