矿渣基无机矿物聚合材料力学性能的研究

目的研究各种原材料的掺量对于矿渣基无机矿物聚合材料抗压强度的影响.方法利用矿渣,高岭土,氢氧化钾,水玻璃等原料制备矿渣基无机矿物聚合材料,并通过对比实验,在单独改变某一因素的情况下,研究矿渣基无机矿物聚合材料抗压强度的变化规律.结果随着固液比、高岭土含量、水玻璃含量和氢氧化钾含量的增加,矿渣基无机矿物聚合材料的抗压强度均呈现出先升高再降低的变化规律.结论固液比的大小在一定的范围内不会对抗压强度产生显著的影响.高岭土占固相的质量分数为20%,水玻璃占液相的质量分数为50%,氢氧化钾占固相的质量分数为18%时,材料获得了最佳的力学性能.

Research on Mechanical Propertity of Slag Based Geopolymer

The effect of the content of raw materical such as kaolin,alkali,water-glass and water on the compressive strengthen of slag based geopolymer is discussed in the paper.The slag based geopolymer is prepared using slag,kaolin,KOH and water-glass.Under the changing single effect,the changing law of the compressive strength of slag based geopolymer is researched by contrast test.The compressive strength of geopolymer increases first and decreases at last with the increasement of the ratio of solid and water,the content of kaolin,water-glass and KOH.The effect of the ratio of solid and water on the compressive strength is not obvious.The mechanical property of geopolymer is perfect when the percentage of kaolin is 20%,the percentage of water-glass is 50% and the percentage of KOH is 18%.
