Tuff and geopolymer composite material and preparation method thereof
The invention discloses a tuff and geopolymer composite material. The composite material comprises tuff, cement and an alkaline activation solution, the ratio of tuff to cement is 1:1 to 3:2, the alkaline activation solution contains SiO2 and Na2O, the ratio of SiO2 to Na2O is 0.7-1.4, and the ratio of tuff to the alkaline activation solution is 0.4-0.5. Tuff and cement are mixed to obtain a mixture A; a sodium silicate solution is composed of 25-30% of SiO2, 8.5-9.5% of Na2O and 63-65% of H2O, and the sodium hydroxide solution and the sodium silicate solution are mixed to prepare the alkalineactivation solution with the molar ratio of SiO2 to Na2O being 0.7-1.4; the alkaline activation solution is mixed with the mixture A to obtain a mixture; and the mixture is poured into a test mold, and is cured to obtain the tuff and geopolymer composite material. Cement with high energy consumption and large pollution can be reduced, and the mixing amount reaches 60%.
本发明公开了凝灰岩地质聚合物复合材料，包括凝灰岩、水泥和碱性活化液，凝灰岩：水泥＝1:1～3:2，碱性活化液中含有SiO和NaO，且SiO：NaO＝0.7～1.4，凝灰岩：碱性活化液＝0.4～0.5。将凝灰岩与水泥混合，获得混合物A；硅酸钠溶液由25％～30％的SiO、8.5％～9.5％的NaO和63％～65％的HO组成，将氢氧化钠溶液和硅酸钠溶液混合配制成SiO/NaO的摩尔比为0.7～1.4的碱性活化液；将碱性活化液与混合物A混合，获得拌制物；将拌制物倒入试模中固化，即可得到凝灰岩地质聚合物复合材料。能少用高耗能污染大的水泥，其掺量达到60％。
