铁路轨枕用蒸养混凝土抗渗性试验研究

采用ASTMC1202试验方法研究了矿物掺合料对蒸养混凝土抗氯离子渗透性能的影响，试验结果表明：单掺粉煤灰可明显降低180d时混凝土6h库仑电量，以10％粉煤灰与20％矿渣组合等量取代水泥时，28d和180d抗氯离子渗透性最佳。

Experimental research on anti-permeability of steaming curing concrete used in railway sleeper

Applying ASTM C1202 experimental method, this paper studies the impacts of mineral admixture on steaming curing concrete anti-permeability of chloride ions. Experimental results show that single fly ash can obviously reduce 6 h coulomb of 180 d concrete, if we use 10% fly ash and 20% slag composite to replace cement, the penetration resistance of chloride ions of 28 d and 180 d is the best.
