掺多元复合矿物外加剂高性能混凝土耐久性

The durability of high performance concrete blended with multivariate composite mineral additive

指出矿物外加剂的复合化是配置高性能混凝土的良好途径,尤其在提高混凝土耐久性方面,发挥了明显的效应,从抗渗性能、抗冻融性能、抗硫酸盐侵蚀性能、抗碳化性能和抵抗碱—集料反应能力等方面,阐述了粉煤灰、矿渣与硅灰多元复合矿物外加剂高性能混凝土的耐久性。

It pointed out that mineral additive compounding was better path to prepare high performance concrete,especially in enhancing concrete durability,which displayed obvious effect.The durability of high performance concrete blended with fly ash,slag and wollastonite multivariate composite mineral additive was illustrated from impervious performance,anti-freezing performance and sulfuric acid erosion resisting,carbonization resisting performance and resisting alkali-aggregate response performance.
