Production method for replacing cement in autoclaved aerated concrete with silicon-manganese alloy smelting slag micropowder
The invention discloses a production method for replacing cement in autoclaved aerated concrete with silicon-manganese alloy smelting slag micro-powder. The production method comprises the following steps: step 1, mixing the silicon-manganese alloy smelting slag micro-powder, a sulfate exciting agent, an alkaline exciting agent and a slow-release agent to obtain a mixture; 2, grinding the mixture in a ball mill, and carrying out mechanical pre-excitation to obtain a pre-excited mixture; and 3, heating the pre-excited mixture, rapidly cooling the pre-excited mixture, and carrying out thermal excitation to obtain the silicon-manganese alloy smelting slag micro powder for replacing cement in the autoclaved aerated concrete. The comprehensive excitation mode of chemical excitation, physical excitation and high-temperature excitation stimulates the activity of the silicon-manganese alloy smelting slag, so that the cement replacement rate of the silicon-manganese alloy smelting slag is effectively increased, the cement consumption is reduced, and the waste utilization rate is increased.
本发明公开了一种用硅锰合金冶炼渣微粉替代蒸压加气混凝土中水泥的生产方法，包括如下步骤：步骤一、将硅锰合金冶炼渣微粉、硫酸盐激发剂、碱性激发剂和缓释剂混合得到混合料；步骤二、将混合料在球磨机内研磨，进行机械预激发，得到预激发混合料；步骤三、将预激发混合料加热后急速冷却，进行热激发，得到替代蒸压加气混凝土中水泥的硅锰合金冶炼渣微粉。本发明化学激发、物理激发和高温激发的综合激发方式，激发了硅锰合金冶炼渣的活性，从而有效提高了其对于水泥的替代率，降低了水泥的用量，提高了废料的利用率。
