Method for producing high-strength lightweight autoclaved aerated concrete from manganese smelting slag micropowder
The invention discloses a method for producing autoclaved aerated concrete with high strength and light weight from manganese smelting slag micro powder. The method comprises the following steps: step 1, mixing activated manganese smelting slag micro powder, cement, sand, gravel and a water reducing agent to obtain a mixture; 2, mixing the mixture with water to obtain concrete; thirdly, concrete is injected into the formwork, demolding and cutting are conducted after preset strength is achieved, then pre-curing is conducted, and a concrete slab is obtained; 4, the concrete slab is subjected to steam curing, and the autoclaved aerated concrete slab is obtained. The activated manganese smelting slag micro powder is used as a main gel material to manufacture the concrete, so that the utilization rate of solid wastes is increased, and the concrete manufacturing cost is saved.
本发明公开了一种锰冶炼渣微粉生产的高强轻质生产蒸压加气混凝土的方法，包括如下步骤：步骤一、将活化的锰冶炼渣微粉、水泥、沙、碎石和减水剂混合得到混合料；步骤二、将混合料与水混合得到混凝土；步骤三、将混凝土注入模板，达到预设强度后进行脱模、切割，然后进行预养护得到混凝土板；步骤四、将混凝土板进行蒸养，得到蒸压加气混凝土板。本发明以活化的锰冶炼渣微粉作为主要的凝胶材料制作混凝体，提高了固体废弃物利用率，节省了混凝土制作的成本。
