| 摘 要： | 粗集料作为混凝土的重要组成材料,其品质直接关系到混凝土的各项性能.通过试验对比研究了碱性矿料石灰岩(ω(SiO_2)为1.01%)和中基性矿料玄武岩(ω(SiO_2)为53.5%)混凝土的抗冻性能,分析了两类试件的质量损失率和相对动弹性模量.结果表明:碱性矿料能够提高混凝土的抗冻性能,这对解决混凝土抗冻性能具有重要意义.

| Abstract: | Coarse aggregate as the important composition of concrete material,its quality is directly related to the various performance of concrete. This paper carried out the alkaline mineral aggregate in limestone (ω( SiO2 ) content of 1. 01%) and basic basalt mineral aggregate (ω( SiO2 ) content of 53. 5%) concrete antifreeze performance contrast test, the quality of the two types of specimen data loss rate and relative dynamic elastic modulus were analyzed, and the results showed that the alkaline mineral aggregate can improve the antifreeze performance of concrete,which is of great significance to solve the concrete frost resistance performance. |
