The invention discloses a waterproof high-strength autoclaved fly-ash brick and a preparation method thereof, and belongs to the technical field of autoclaved fly-ash bricks. The waterproof high-strength autoclaved fly-ash brick comprises the following raw materials in parts by weight: 30-50 parts of fly ash, 10-20 parts of aeolian sand, 3.6-5.8 parts of stone chips, 2.3-4.3 parts of calcium oxide, 4.5-6.5 parts of mica powder, 3.8-6.0 parts of lignin, and 6.8-9.0 parts of a waterproof agent. The waterproof high-strength autoclaved fly ash-lime brick is prepared by the steps of preparing modified mica powder, mixing and aging, ball-milling, reversing a mold, making the brick and the like. A waterproof agent is prepared, has a hydrophobic side chain and carboxyl, and can be tightly combined with mica powder, so that the prepared brick has good strength and waterproof performance.
本发明公开了一种防水高强度蒸压粉煤灰砖及其制备方法，属于蒸压粉煤灰砖技术领域，该防水高强度蒸压粉煤灰砖，包括如下重量份原料：粉煤灰30‑50份、风积沙10‑20份、石屑3.6‑5.8份、氧化钙2.3‑4.3份、云母粉4.5‑6.5份、木质素3.8‑6.0份、防水剂6.8‑9.0份，该防水高强度蒸压粉煤灰砖由制备改性云母粉、混合陈化、球磨、倒模、制砖等步骤制成；其中制备了一种防水剂，带有疏水侧链和羧基，可以与云母粉紧密结合，使制得砖具有良好的强度与防水性能。
