摘要
通过正交试验设计对无砂混凝土抗冻性的影响因素进行分析,采用比较先进的快冻法评价无砂混凝土的抗冻性,实验结果表明:集灰比影响非常显著,集料粒级次之。
This paper adopts orthogonal experiment design and relatively advanced Fast Freezing Method to test no-fines concrete. Resuits show that aggregate-cement ratio is the most significant factor to influence the frost resistance of no-fines concrete, while aggregate gradation is the second important.
