煅烧高铝煤矸石-矿渣-水玻璃系地聚合物材料的研究

根据地聚合物合成原理，采用煅烧高铝煤矸石-磨细矿渣-水玻璃系合成地聚合物类材料。深入研究了高铝煤矸石-矿渣-水玻璃系统材料的制备、性能的测试评价、水化硬化机理和最优制备工艺参数选择。材料中矿渣对早期强度起主要作用，煅烧高铝煤矸石对后期强度贡献较大。在矿渣和高铝煤矸石质量比处于合理状态时，材料各龄期强度均较优。高铝煤矸石类地聚合物材料的抗压强度随水玻璃模数的减小而增大，随水玻璃掺量的增大而增大，随液胶比的减小而增大。水玻璃模数为1．049，矿渣与煅烧高铝煤矸石的配比为4：6，激发剂掺量为22％，液胶比为0．35时，复合材料28d抗压强度达到了41．7MPa。

Study on geoploymerisation materials composed of sintered coal gangue with high Al2O3 content-GGBS-water glass system

The geopolymeric materials was composed by sintered high alumina coal gangue-slag-soluble glass system according to geopolymer theory including preparation,test and estimate of performance,mechanism of hydration and hardening and optimal parameter of technics.The slag in the system played a main role on the materials early strength and the high alumina coal gangue affected the later strength.The materials strength at each age was good when the mass proportion of two elements was proper.The compressive strength of materials increased as the modulus of soluble glass and water-binder ratio decreased and content of the soluble glass increase.The compressive strength of materials was 41.7MPa when the modulus of soluble glass was 1.049,the mass proportion of slag and high alumina coal gangue was 4:6,the mass proportion of blazing agent was 22% and the proportion of liquid and glue was 0.35.
