Autoclaved aerated concrete block and preparation method thereof
The invention discloses an autoclaved aerated concrete block. The autoclaved aerated concrete block comprises, by weight, 80-120 parts of lime, 40-60 parts of cement, 400-500 parts of fly ash, 150-200 parts of steel slag, 50-120 parts of iron tailings, 70-90 parts of gypsum, 10-16 parts of aluminum powder, 60-120 parts of an air entraining agent and 10-20 parts of a modified foaming agent. The invention further discloses a preparation method of the autoclaved aerated concrete block. The invention relates to the technical field of production of concrete blocks, and concretely provides the autoclaved aerated concrete block and the preparation method thereof. By adding steel slag and tailing iron ore, the problem that the autoclaved aerated concrete block is low in strength due to addition of fly ash is solved to a great extent; and the steel slag and the iron tailings are low in economic cost and suitable for comprehensive popularization.
本发明公开了一种蒸压加气混凝土砌块，包括下列重量份数的组份：石灰80‑120份、水泥40‑60份、粉煤灰400‑500份、钢渣150‑200份、尾铁矿50‑120份、石膏70‑90份、铝粉10‑16份、加气剂60‑120份和改性发泡剂10‑20份，并公开了一种蒸压加气混凝土砌块的制备方法。本发明涉及混凝土砌块生产技术领域，具体提供了一种蒸压加气混凝土砌块及制备方法，通过钢渣和尾铁矿的添加，极大程度的解决了因粉煤灰添加引起蒸压加气混凝土砌块强度低的问题；且钢渣和尾铁矿的经济成本低，适宜于全面推广。
