High-strength autoclaved sand-lime brick and production and processing method thereof
The invention discloses a high-strength autoclaved sand-lime brick. The concrete is prepared from the following raw materials in parts by weight: 30-45 parts of fly ash, 8-24 parts of Portland cement, 2-5 parts of quick lime, 50-80 parts of sand, 4-12 parts of aggregate, 0.2-0.8 part of retarder, 2-4 parts of modifier A, 2-4 parts of modifier B, 5-13 parts of desulfurized fly ash, 1-3 parts of defoaming agent, 4-12 parts of polymer latex powder, 3-6 parts of basalt fiber, 0.1-0.8 part of polypropylene fiber, and 30-45 parts of water. By adding the fly ash, the sand and the aggregate, resource recovery is facilitated, and land occupation and environmental pollution caused by accumulation of a large amount of construction waste and coarse slag ash are reduced; and the bonding force between the basalt fibers and the polypropylene fibers and mortar is enhanced, the crack resistance of the lime-sand brick is improved, when the lime-sand brick is impacted, the fibers have good elasticity, impact stress is borne by longitudinal bending of the fibers, the compressive strength is improved, and therefore the mechanical strength of the lime-sand brick is enhanced.
本发明公开了一种高强度蒸压灰砂砖，其原料按重量份重量计如下：粉煤灰为30‑45份、硅酸盐水泥为8‑24份、生石灰为2‑5份、砂子为50‑80份、骨料为4‑12份、缓凝剂为0.2‑0.8份、改性剂A为2‑4份、改性剂B为2‑4份、脱硫灰为5‑13份、消泡剂为1‑3份、聚合物乳胶粉为4‑12份、玄武岩纤维为3‑6份、聚丙烯纤维为0.1‑0.8份、水为30‑45份。本发明通过粉煤灰、砂子和骨料的加入，便于资源回收，降低了大量建筑垃圾和粗渣灰堆积造成的土地占有和环境污染；玄武岩纤维和聚丙烯纤维与砂浆的结合力增强，提高灰砂砖的抗裂性，在灰砂砖受到冲击作用时，纤维具有很好的弹性，冲击应力被纤维的纵向弯曲承受，提高了抗压强度，从而使灰砂砖机械强度得到增强。
