| 摘 要： | 通过试验测试研究珍珠岩矿物掺合料及其对混凝土主要性能的影响，在混凝土中珍珠岩掺合料替代水泥10％～20％可不同程度地改善工作性能，提高后期强度。该掺合料替代水泥20％制备C60混凝土铁道Ⅲ型轨枕的试验及其检测结果显示其主要性能指标均有所提高。

| Abstract: | The experimental data about concrete mixed with perlite admixture showed that perlite admixture in 10%-20% amount of replacing cement enhanced effectively the workability, late-age mechanical strength and durability for concrete. The railway sleepers made of C60-Grade concrete with perlite admixture in 20% amount of replacing cement were probingly produced in producing-line of factory. The summary was concluded that the railway sleepers made of concrete with 20% perlite admixture not only satisfied standards of product quality, but also prior to railway sleepers made of concrete without admixture on major properties. |
