Solid-waste-containing light-weight, heat-preservation and high-strength geopolymer and preparation method thereof
The invention discloses a solid waste-containing light-weight, heat-preservation and high-strength geopolymer and a preparation method thereof. The geopolymer is prepared from the following components in parts by weight: 0.01-0.5 part of silicon dioxide aerogel, 0.1-0.6 part of silica fume, 5-15 parts of fly ash hollow microspheres, 0.5-1.5 parts of sodium hydroxide, 3-9 parts of water glass and 1-4 parts of water. Wherein the silicon dioxide aerogel is injected into cavities of the fly ash hollow microspheres. According to the light-weight, heat-preservation and high-strength geopolymer containing the solid waste and the preparation method of the geopolymer, the solid waste of the fly ash hollow microspheres is adopted as a raw material, the utilization rate of the solid waste is effectively increased, low carbon and environment friendliness are achieved, the silicon dioxide aerogel is injected into cavities of the hollow microspheres through a vacuum method, and through the coupling effect of the silicon dioxide aerogel and the hollow microspheres, the light-weight, heat-preservation and high-strength geopolymer containing the solid waste is obtained. And the concrete density can be effectively reduced by doping into concrete, and light thermal insulation concrete can be prepared.
本发明公开了一种含固废的轻质‑保温‑高强地质聚合物及其制备方法，地质聚合物按照重量份数包括二氧化硅气凝胶0.01‑0.5份、硅灰0.1‑0.6份、粉煤灰空心微珠5‑15份、氢氧化钠0.5‑1.5份、水玻璃3‑9份和水1‑4份，其中二氧化硅气凝胶注入到粉煤灰空心微珠的空腔内。本发明采用上述结构的一种含固废的轻质‑保温‑高强地质聚合物及其制备方法，不仅采用粉煤灰空心微珠的固废作为原料，有效提高固废的利用率，低碳环保，而且采用真空法将二氧化硅气凝胶注入到空心微珠空腔内，二者耦合作用，掺入到混凝土中可以有效降低混凝土密度，制备轻质保温混凝土。
