Modified autoclaved aerated concrete double-hole self-insulation building block and preparation method thereof
The invention relates to the field of insulating bricks, in particular to a modified autoclaved aerated concrete double-hole self-insulating building block and a preparation method thereof. The building block comprises the following raw materials in parts by weight: 67-72 parts of a siliceous material; 24 to 29 parts of a calcium material; 0.08 part of aluminum powder; 3-5 parts of gypsum; and 0.92 part of an additive. The preparation method of the building block comprises the following steps: uniformly mixing the siliceous material, the gypsum and the additive according to the weight ratio to prepare a mixture; water is added into the mixture, so that the diffusivity of the mixture reaches 25 cm to 30 cm; pouring the mixture into a stirrer, keeping the temperature at 38-40 DEG C, adding the calcium material, stirring for 1 minute, adding the aluminum powder, and continuously stirring for 15 minutes; the finally stirred mixture is injected into a mold for gas generation, and the mixture is hardened into a green body; and demolding, and segmenting the green body. The modified autoclaved aerated concrete double-hole self-heat-preservation building block disclosed by the invention is high in strength, low in heat conductivity coefficient and good in heat preservation effect.
本发明涉及保温砖领域，具体是一种改性蒸压加气混凝土双孔自保温砌块及其制备方法。该砌块包括以下重量份的原料：硅质材料67‑72份；钙质材料24‑29份；铝粉0.08份；石膏3‑5份；添加剂0.92份。该砌块的制备方法如下：按照重量比例将硅质材料、石膏和添加剂混合均匀，制成混合料；向混合料中加入水，使混合料的扩散度达到25cm‑30cm；将混合料倒进搅拌机中，温度保持在38℃‑40℃，加入钙质材料，搅拌一分钟后加入铝粉继续搅拌15分钟；将最终搅拌好的混合料注入模具中进行发气，使混合料硬化成坯体；脱模，对坯体进行分割。本发明公开的改性蒸压加气混凝土双孔自保温砌块，强度高，导热系数低，保温效果好。
