Red mud aerated brick
The invention relates to the technical field of building materials, and particularly discloses a red mud aerated brick, which is prepared by the following steps: putting cement, phosphorus slag, quick lime, gypsum and quartz sand into a reaction kettle in parts by mass, adding water, and stirring at the speed of 1500-2500r/min for 10-15min to obtain a material A; coal cinder and red mud are subjected to high-temperature calcination for 4-5 h and then ground into powder, and a material B is obtained; adding the material B into a reaction kettle containing the material A, stirring for 5 minutes at the speed of 2000r/min, adding a bubble stabilizer and a regulator, and stirring for 25 minutes at the speed of 800-1000r/min to obtain a mixed material; pouring the mixed material into a mold for molding, standing for more than 3 hours in an environment of 45 DEG C, demolding, building blocks, and performing steam curing to obtain the red mud aerated brick. The reaction kettle comprises an inner shell and an outer shell, the inner shell is connected with the inner bottom of the outer shell, an air chamber is arranged between the inner shell and the outer shell, and a spindle is arranged in the top center of the inner shell and the outer shell. The compressive strength and freeze-thaw resistance of the aerated brick are improved, and the problem that a large number of bubbles exist in the stirring process is solved.
本申请涉及建筑材料技术领域，具体公开了一种赤泥加气砖，按照质量份将水泥、磷矿渣、生石灰、石膏、石英砂放置在反应釜中，加水后以1500‑2500r/min的速度搅拌10‑15min得到物料A；将煤渣、赤泥进行高温煅烧4‑5小时后磨成粉状得到物料B；将物料B加入含有物料A的反应釜中，以2000r/min的速度搅拌5min后，加入气泡稳定剂、调节剂以800‑1000r/min的速度搅拌25min即得到混合物料；将混合物料浇注入模具内成型，并在45℃环境下静置3h以上，脱模，砌块，蒸汽养护，即得赤泥加气砖；反应釜包括内壳和外壳，内壳与外壳的内底部连接，内壳与外壳之间设置有气室，内壳与外壳的顶部中心设置有主轴。本申请专利提升了加气砖的抗压强度、抗冻融性能，减少了搅拌过程中含有大量气泡的问题。
