摘要
针对长白山天然浮石轻骨料混凝土,对强度等级在LC30以上的不同引气剂掺量的混凝土试件进行系列冻融循环试验,主要考察和研究该浮石混凝土在冻融循环后混凝土的质量和强度损失率的变化。通过试验对比和理论分析研究了该浮石轻骨料混凝土在引气作用下的抗冻耐久性能。
As to the natural pumice lightweight aggregate concrete in Changbai mountains in China,the strength grade above LC30 concrete specimens of different dosage of air-entraining admixtures have been carried series of freeze-thaw cycling tests to mainly investigate and research on the concrete quality and the strength loss rate changes of pumice concrete after freeze-thaw cycle tests.Through the contrast tests and theoretical analysis,the antifreeze durable performance of this pumice lightweight aggregate concrete under the action of air-entraining has been studied.
