锰渣水泥混凝土在港航工程中的应用研究

Application of manganese slag-cement concrete in harbor and channel engineering

通过利用0、5%、10%、15%、20%、25%、30%的锰渣废弃物矿渣代替同体积水泥配制成的混凝土进行力学性能、干缩性能、抗冲磨性能等方面的试验研究和分析,发现当锰渣废弃物矿渣代替量小于15%时,对混凝土在港航工程的水工建筑物上的应用各方面性能的影响微小,但能降低混凝土的生产成本和具有一定的社会环保价值。为锰渣废弃物矿渣在港航工程的水工建筑物上的应用提供依据。

The concrete is mixed with the manganese slag replacing the same volume of cement.The mixed volume includes 5%, 10%, 15%, 20%, 25% and 30%.Through the experimental study and analysis on the properties of mechanics, shrinkage and souring resistance of the concrete, mixing the manganese slag with a volume of less than 15% has no impact on the properties of concrete of the hydraulic construction in harbor and channel engineering,but it reduces the cost and conserves the environment.
