Lightweight high-strength ceramsite concrete mixture and preparation method thereof
The invention relates to a light high-strength concrete mixture and a preparation method thereof. The mixture is prepared from the following raw materials in parts by weight: 354.32 to 477.9 parts of cement, 79.7 to 121.28 parts of fly ash, 79.7 to 121.28 parts of silica fume, 79.7 to 161.7 parts of mineral powder, 36.6 to 54.9 parts of fly ash floating beads, 36.6 to 54.9 parts of glass beads, 78.08 to 107.36 parts of shale ceramsite, 87.84 to 117.12 parts of clay ceramsite, 6.45 to 9.675 parts of a water reducing agent and 107.6 to 143.4 parts of water. The preparation method comprises the following steps: S1, adding the dry materials into a stirrer for stirring, so that all the dry materials are fully mixed; s2, dissolving a water reducing agent in water, adding the dry material mixed in the step S1, and uniformly mixing by using a stirrer to obtain the lightweight high-strength ceramsite concrete, the fly ash floating beads are matched with the glass beads, the shale ceramsite and the clay ceramsite, so that the volume density of the concrete is reduced, the lightweight property of the concrete is realized, and meanwhile, the concrete also has the strength required by an engineering structure.
一种轻质高强混凝土拌合料及其制备方法，拌合料包括如下重量份的原料：水泥354.32～477.9份、粉煤灰79.7～121.28份、硅灰79.7～121.28份、矿粉79.7～161.7份、粉煤灰漂珠36.6～54.9份、玻化微珠36.6～54.9份、页岩陶粒78.08～107.36份、粘土陶粒87.84～117.12份、减水剂6.45～9.675份、水107.6～143.4份；制备方法是：S1、将干料加入搅拌机中搅拌，使得所有干料充分混合；S2、将减水剂溶于水后加入步骤S1中混合好的干料并使用搅拌机均匀混合，得到轻质高强陶粒混凝土；本发明通过粉煤灰漂珠与玻化微珠、页岩陶粒与粘土陶粒的配合，降低混凝土的体积密度，实现混凝土的轻质性，同时混凝土也具有工程结构所需的强度。
