Geopolymer concrete and preparation method thereof
The invention relates to the technical field of constructional engineering, and discloses geopolymer concrete and a preparation method thereof. The geopolymer concrete is prepared from the following raw material components in parts by mass: 120 to 140 parts of mineral powder, 40 to 50 parts of fly ash, 20 to 30 parts of silica fume, 210 to 230 parts of fine aggregate, 80 to 90 parts of alkali activator and 90 to 170 parts of composite shrinkage reducing agent, wherein the alkali activator contains strong alkali, silicate, carbonate and water. The method for preparing the geopolymer concrete comprises the following steps of: (1) performing mixing I on strong base, silicate, carbonate and water to obtain an alkali activator; (2) performing mixing II on mineral powder, fly ash, silica fume, a composite shrinkage reducing agent and fine aggregate II to obtain a mixture; and (3) performing mixing III ON the alkali activator obtained in the step (1) with the mixture obtained in the step (2) to obtain a mixture III. The geopolymer concrete provided by the invention has excellent mechanical and durability, and is low in production cost and simple in preparation process.
本发明涉及建筑工程技术领域，公开了一种地聚物混凝土及其制备方法。地聚物混凝土含有以下原料组分，按质量份计为：矿粉120‑140份、粉煤灰40‑50份、硅灰20‑30份、细骨料210‑230份、碱激发剂80‑90份、复合减缩剂90‑170份；其中，所述碱激发剂含有强碱、硅酸盐、碳酸盐和水。制备地聚物混凝土的方法包括以下步骤：(1)将强碱、硅酸盐、碳酸盐和水进行混合I得到碱激发剂；(2)将矿粉、粉煤灰、硅灰、复合减缩剂和细骨料进行混合II得到混合料；(3)将步骤(1)得到的所述碱激发剂和步骤(2)得到的所述混合料进行混合III。本发明提供的地聚物混凝土具有优良的力学和耐久性能，且生产成本低、制备过程简单。
