摘要
通过对国内外微波热活化高岭土、微波研制纳米级硅酸盐产物和以SiC为基座包裹A12O3使A12O3直接吸收微波能等相关研究工作的分析,以及根据本课题组前期对微波活化高岭质煤矸石-硅酸盐水泥复合胶凝材料其强度、细度、凝结时间、体积安定性测试和对微波活化高岭质煤矸石火山灰活性指数的测定,在硅酸盐水泥中掺加一定量的微波活化高岭质煤矸石可获得符合国家相关规范及技术标准要求的煤矸石-硅酸盐水泥,并由此提出了可利用微波技术热活化不同种类的高岭质矿物,使其成为优良的水泥辅助性胶凝组分,实现在生产水泥辅助性胶凝组份高效、节能、减排的目的。
Through the analysis of microwave thermal activation of kaolin, microwave preparation ot nano-smcate products and the direct absorption of microwave energy taking SiC as base pachage, as well as the test of strength, fineness, setting time and volume stability of composite cementitious materials of portland cement and the determina- tion of the activation indexes of activating kaolin minerals by microwave irradiation, the gangue-portland cement meeting the requirements of the relevant national standards and the technical standards was obtained when a certain amount of microwave activation of kaolin gangue was added. Therefore, it was put forward to that different kinds of kaolin minerals could be activated by using microwave technology, making it act as supplementary cementing compo- nents, reaching the aim of high-efficiency, energy-saving and emission reduction.
