Optimized ratio and preparation method of recycled GFRP powder and slag-based geopolymer cementing material
The invention discloses an optimized ratio and a preparation method of a recycled GFRP powder and slag based geopolymer cementing material, the cementing material comprises the following components by weight: 5%-42% of recycled GFRP powder, 17%-53% of slag, and 40%-47% of an alkali-activated solution, the concentration of the alkali-activated solution is 75%-85%; the modulus of the alkali-activated solution is 1.3-1.5; the liquid-solid ratio is 0.7 to 0.9. The recycled GFRP powder and the slag are taken as precursors of the geopolymer, and the recycled GFRP powder and slag binary geopolymer is formed through reasonable material combination and proportioning, so that environmental pollution and resource waste caused by GFRP waste are reduced, and the flash coagulation problem of the slag geopolymer in the preparation process and the problem of high contractility during maintenance are solved. The geopolymer concrete can be prepared by replacing a cement binding material, and the geopolymer concrete can also be directly used as a binding material.
本发明公开了一种回收GFRP粉末与矿渣基地聚物胶凝材料优化配比及制备方法，该胶凝材料包括以下重量百分比的组份：回收GFRP粉末为5％～42％，矿渣为17％～53％，碱激发溶液为40％～47％，其中碱激发溶液浓度为75％～85％；碱激发溶液模数为1.3～1.5；液固比为0.7～0.9。本发明以回收GFRP粉末和矿渣为地聚物的前驱物，通过合理的材料组合与配比，形成回收GFRP粉末与矿渣二元地聚物，降低GFRP废弃物对环境的污染和资源浪费，改善矿渣地聚物在制备过程中的闪凝问题及养护时收缩性大的问题。既可用替代水泥胶凝材料制备地聚物混凝土也可直接当做粘结材料。
