Dry mixing material for square stock type inorganic artificial stone, inorganic artificial stone and preparation method
The invention relates to the field of inorganic artificial stones, and particularly discloses a dry mixing material for square stock type inorganic artificial stones, the inorganic artificial stones and a preparation method. The dry mixing material comprises the following components in percentage by weight: 20-30% of an inorganic composite cementing material, 10-40% of superfine active mineral powder, 30-60% of aggregate, 0.5-2% of a powder water reducing agent and 0-1% of pigment; wherein the inorganic composite cementing material comprises the following components in percentage by weight: 70-80% of Portland cement and 20-30% of high belite cement, the strength grade of the Portland cement is more than 42.5, and the content of beta-C2S in the high belite cement is more than 60%; the inorganic artificial stone is prepared by adding water into the dry mixed material. The dry mixing material releases heat gently in the hydration process, the total amount of released hydration heat is low, the thermal stress in the inorganic artificial stone is reduced, the early strength is obviously high, and the prepared inorganic artificial stone is excellent in crack resistance.
本申请涉及无机人造石领域，具体公开了一种用于方料式无机人造石的干拌料、无机人造石及制备方法。干拌料包括以下重量百分比的组分：无机复合胶凝材料20%~30%、超细活性矿粉10%~40%、骨料30%~60%、粉体减水剂0.5%~2%、颜料0~1%；其中，无机复合胶凝材料包括70%~80%重量百分比的硅酸盐水泥和20%~30%重量百分比的高贝利特水泥，硅酸盐水泥的强度等级为42.5级以上，高贝利特水泥的β‑C2S含量为60%以上；无机人造石由上述干拌料加水制成。本申请干拌料在水化过程中放热平缓且释放的水化热总量低，减轻了无机人造石内部的热应力，且早期强度明显高，制得的无机人造石的抗裂性能优异。
