Foam concrete and production process thereof
The invention discloses foam concrete and a production process thereof. The foam concrete comprises the following components: water; cement; a foaming agent; stone powder; coal ash; a binder; gravel; an anti-crack fiber; light foam; and an antioxidant. According to the foam concrete, the mode of adding the light foam particles is adopted, the light foam particles in the molten state are fused into the concrete, at the moment, light foam is the maximum heat which can be absorbed by the light foam particles and is also the deformation which can be generated by the light foam particles to the maximum extent, and therefore, when the foam concrete is used in the later period, the problem that the concrete is extruded due to expansion is avoided, the volume of the light foam condensed at low temperature is reduced due to rapid cooling, the number of cavities in the concrete is increased, the mass of the foam concrete is reduced again, later use and transportation are facilitated, and space difference is formed between the condensed light foam and the cavities, and a gap is formed between the light foam particles and the inner wall of the cavity, so a certain deformation space can be provided in a high-temperature exposure environment.
本发明公开了一种泡沫混凝土及其生产工艺，包括以下成分：水；水泥；发泡剂；石粉；粉煤灰；粘合剂；砂石；抗裂纤维；轻质泡沫；抗氧化物，该泡沫混凝土，采用添加轻质泡沫颗粒的方式，在熔融状态的轻质泡沫颗粒融入混凝土中，此时轻质泡沫是其所能吸收的最大热量，也是其最大程度所能产生的形变，这样在后期使用的泡沫混凝土的时候，避免发生膨胀挤压混凝土的问题，低温冷凝过后的轻质泡沫由于快速冷却收缩体积，增加了混凝土中的空洞数量，再一次降低了泡沫混凝土的质量，方便后期使用和运输，冷凝后的轻质泡沫还会与空洞之间形成空间差，即轻质泡沫颗粒与空洞内壁之间有间隙，这样在高温暴晒的环境中可以提供一定的形变空间。
