Steam pressurized concrete block and production method thereof
The invention discloses a steam pressurized concrete block and a production method thereof, and relates to the technical field of concrete blocks, the steam pressurized concrete block comprises the following raw materials by mass: 30%-40% of fly ash, 15%-20% of quick lime, 10%-20% of cement, 10%-15% of gypsum, 5%-10% of slag, 5%-10% of silica sand and auxiliary ingredients, the auxiliary ingredients comprise the following raw materials in percentage by mass: 2-5% of a fixing agent, 1-3% of a foaming agent, 2-5% of a regulator, 1-3% of a stabilizer and 2-5% of a strength improver. The strength improver is mainly water calcium silicate crystal grains, the water calcium silicate crystal grains can react to generate hydrated calcium silicate gel in a humid and hot environment, and along with the increase of the hydrated calcium silicate gel, the strength of the lime-sand brick is improved, and the situation that the steam pressurized concrete block is broken can be avoided.
本发明公开了一种蒸汽加压混凝土砌块及其生产方法，涉及混凝土砌块技术领域，包括以下质量百分比的原料组成：粉煤灰30％‑40％、生石灰15％‑20％、水泥10％‑20％、石膏10％‑15％、矿渣5％‑10％、硅砂5％‑10％和辅助配料，所述辅助配料由以下质量百分比的原料组成：固定剂2％‑5％、发气剂1％‑3％、调节剂2％‑5％、稳定剂1％‑3％和强度改善剂2％‑5％。本发明强度改善剂主要为水硅酸钙晶粒，在湿热的环境下，水硅酸钙晶粒会发生反应生成水化硅酸钙凝胶，随着水化硅酸钙凝胶的增多，从而提高了灰砂砖的强度，可避免蒸汽加压混凝土砌块碎裂的情况发生。
