摘要
运用干湿循环的实验方法研究了LC30基准轻骨料混凝土及损伤度为0~0.1、0.1~0.2、0.2~0.3的受损轻骨料混凝土的抗硫酸盐侵蚀的性能,以相对动弹性模量为评价指标,分析了损伤度对基准轻骨料混凝土、掺粉煤灰轻骨料混凝土及掺聚丙烯纤维轻骨料混凝土的抗硫酸盐侵蚀性能,并建立了以粉煤灰掺量、聚丙烯纤维掺量为指标的轻骨料衰变损伤模型。
The sulfate erosion resistance of LC30 lightweight aggregate concrete and concrete with different damage degrees of 0-0. 1,0. 1-0. 2,0. 2-0. 3 was investigated by dry-wet cycles. The influence of damage degree on the sulfate resistance of concrete、lightweight aggregate concrete with fly ash and lightweight aggregate concrete with polypropylene fiber via the dynamic elastic modulus. The damage model of lightweight aggregate concrete based on the index of fly ash volume and polypropylene fiber volume is established.
