摘要
研究了LC45高强轻集料混凝土掺加磨细矿渣和粉煤灰后,在强度、收缩、抗冻、抗氯离子渗透性能以及弹性模量方面的影响。综合其各项性能指标的影响程度,提出了矿粉和粉煤灰复合应用于高强轻集料混凝土中的合理方法和配比范围。
The influences of the fly ash and ground slag on performances of the strength, contraction, frost-resistance, impervious of Cl- and elasticity modulus of the LC45 light-weight concrete was researched. The rational application method and proportional ratio of combined mixtures with fly ash and ground slag for light-weight concrete.was put forward.
