Preparation method of light high-strength building brick
The invention discloses a preparation method of a light high-strength building brick. The preparation method comprises the following steps: drying foundation sludge for 1-2 hours at the drying temperature of 80-100 DEG C, adding light corundum, light calcined magnesia and calcined alumina micro powder, uniformly mixing, and then uniformly grinding at the pressure of 15-25 kPa to obtain a sludge compound; adding carboxymethyl cellulose and sodium tripolyphosphate into water, uniformly mixing, adding the sludge compound, uniformly stirring, adding a foaming agent in a stirring state, and uniformly stirring to obtain a castable; and uniformly casting the castable, drying and sintering to obtain the light high-strength building brick. The sintering method comprises the following specific operation steps: heating a green body obtained by baking from normal temperature to 300-400 DEG C, preserving heat for t1 hour, cooling to 200-250 DEG C, and preserving heat for t2 hours; then heating to 1200-1300 DEG C, performing heat preservation for t3 h, cooling to 900-1000 DEG C, and performing heat preservation for t4 h; and continously heating to 1400-1450 DEG C, and performing heat preservation for t5 h.
本发明公开了一种轻质高强度建筑用砖的制备方法，包括如下步骤：将地基淤泥干燥1‑2h，干燥温度为80‑100℃，加入轻质刚玉、轻烧氧化镁、煅烧氧化铝微粉混合均匀，然后15‑25kPa研磨均匀得到淤泥复合物；向水中加入羧甲基纤维素、三聚磷酸钠混合均匀，加入淤泥复合物搅拌均匀，搅拌状态下加入发泡剂搅拌均匀得到浇注料；将浇注料浇铸均匀，干燥，烧结得到轻质高强度建筑用砖。烧结的具体操作如下：将烘烤所得坯体从常温升温至300‑400℃，保温t1h，降温至200‑250℃，保温t2h；再升温至1200‑1300℃，保温t3h，降温至900‑1000℃，保温t4h；继续升温至1400‑1450℃，保温t5h。
