Cement foamed concrete and preparation process thereof
The invention belongs to the technical field of foamed concrete, and particularly relates to cement foamed concrete and a preparation process thereof. The foaming ball is of a cavity type sphere structure, wherein hydrogen peroxide is contained in the foaming ball, the foaming ball body comprises sodium stearate and n-hexadecanol, and uniformly distributed micropores are formed in the surfaces of the foaming ball. According to the invention, a foaming agent and a foam stabilizer are made into a sphere structure, in a stirring and mixing process of cement concrete, the foaming ball is placed in cement paste, heat of the cement is dissipated in the water adding and stirring process, then the temperature in the cement paste is increased, an aqueous solution enters the foaming ball along micropores in the surface of the foaming ball to be mixed with hydrogen peroxide, the hydrogen peroxide is decomposed to generate gas by utilizing water temperature while the inner wall of the foaming ball is dissolved by utilizing the temperature to be mixed with water to form a foam stabilizer, and the gas rushes out of the foam stabilizer and impacts outwards through the micropores, so that the volume of bubbles is reduced by utilizing the micropores.
本发明属于发泡混凝土技术领域，具体的说是一种水泥发泡混凝土及其制备工艺，所述发泡球为空腔式球体结构；所述发泡球内部承装有双氧水；所述发泡球球体包含硬脂酸钠和正十六醇；所述发泡球表面开设有均匀分布的微孔，本发明通过将发泡剂以及稳泡剂制成球体结构，在进行水泥混凝土的搅拌混合过程中，通过将发泡球置于水泥泥浆中，水泥在加水搅拌的过程中自身进行热量的散发，进而使水泥泥浆中的温度升高，水溶液顺着发泡球表面的微孔进入发泡球的内部与双氧水混合，并利用水温使双氧水进行分解生成气体，同时温度使发泡球内壁溶解与水混合形成稳泡剂，气体从稳泡剂中冲出，并经过微孔向外冲击，进而使利用微孔使气泡的体积缩小。
