Preparation method of high-strength impermeable aerated brick
The invention discloses a preparation method of a high-strength impermeable aerated brick. The preparation method comprises the following operation steps: S1, grinding fly ash; S2, crushing the lime and the ardealite; S3, adding the aluminum powder into a stirrer to form an aluminum powder suspension; S4, preparing an adhesive; S5, adding the treated fly ash, cement, lime and ardealite into a pouring stirrer according to the proportion for slurry stirring, and then adding the treated materials such as the adhesive; and S6, after pouring, conveying the mixture to a culture room for gas forming and initial setting, and at the moment, completing preparation of the aerated brick. According to the preparation method of the high-strength impermeable aerated brick, the overall compressive strength, breaking strength and freezing resistance of the aerated brick can be improved by adding the adhesive, the shrinkage limit rate and water absorption rate of the aerated brick can be reduced to a certain extent, and by adding the water reducing agent, and under the condition that the workability of the aerated brick is kept unchanged, the strength of the aerated brick can be improved without increasing the cement consumption.
本发明公开了一种高强度防渗透加气砖的制备方法，包括以下操作步骤：S1：将粉煤灰磨细；S2：将石灰和磷石膏破碎；S3：铝粉添加至搅拌机中，使其成为铝粉悬浮液；S4：制作出黏结剂；S5：按份额将处理好的粉煤灰、水泥、石灰、磷石膏加入浇注搅拌机内进行料浆搅拌，再加入处理好的黏结剂等材料；S6：浇注后将其输送至培养室进行发气初凝，此时完成加气砖的制备。本发明的一种高强度防渗透加气砖的制备方法，通过添加的黏结剂，可提高加气砖整体的抗压强度，抗折强度和耐冻强度，且能一定程度上减少加气砖的限缩率和吸水率，通过添加的减水剂，可保持加气砖工作性不变的条件下，且不增加水泥用量，就可提高加气砖的强度。
