Preparation method of building foamed concrete
The invention is suitable for the technical field of foamed concrete preparation, and provides a building foamed concrete preparation method which comprises the following specific operation steps: S1, preparing a foaming agent, S2, preparing a dry-mixed raw material, S3, preparing a liquid raw material, and S4, after the dry-mixed raw material in the step S2 is stirred, rapidly adding a certain weight part of the liquid raw material prepared in the step S2 into a mortar pot, and uniformly stirring. Continuously and mechanically stirring for 5 minutes to obtain cement paste; s5, adding the foaming agent obtained in the step S1 into the cement paste obtained in the step S4, and continuously stirring for 10-15 minutes until floating foam does not exist; s6, under the air pressure of 1.5 MPa, the slurry in the step S5 is infiltrated into a basalt fiber felt of 150 kg/m < 3 >, foaming is conducted, and the foamed concrete is obtained, the foam concrete is high in strength and stable in foam effect, the conditions of insufficient expansion rate and uneven foam cannot be generated in the machining process, and the use and yield of products are guaranteed.
本发明适用于发泡混凝土制备技术领域，提供了一种建筑发泡混凝土制备方法，具体操作步骤如下：S1、发泡剂制备，S2、干拌原料制备，S3、液体原料制备，S4、当S2步骤中干粉原料搅拌完成后，迅速向砂浆锅中加入一定重量份的加入S2步骤所制备的液体原料，持续机械搅拌5min，得到水泥浆体；S5、向上述S4步骤中得到的水泥浆体中加入S1步骤所得到的发泡剂，持续搅拌10‑15min，搅拌至没有漂浮泡沫即可；S6、将S5步骤中的浆体在1.5MPa的空气压力下，将浸润至150kg/m3的玄武岩纤维毡中，发泡，即得发泡混凝土，该泡沫混凝土强度高，同时泡沫效果稳定，加工过程中不会产生膨化率不足和泡沫不均的情况，保障了产品的使用和成品率。
