Foamed concrete and preparation method thereof
The invention relates to the technical field of foamed concrete, in particular to foamed concrete and a preparation method thereof, and the preparation method of the foamed concrete comprises the following steps: (1) taking fine aggregate and cement, and uniformly stirring and mixing to obtain a dry material; (2) taking a foam stabilizer and water, and introducing CO2 into the foam stabilizer and the water for foaming to form a foam solution; (3) adding the foam solution obtained in the step (2) into the dry material obtained in the step (1), and uniformly stirring and mixing to obtain concrete slurry; (4) taking a foaming agent according to the mass ratio, adding the concrete slurry, and uniformly stirring to obtain foamed concrete slurry; (5) pouring the foamed concrete slurry into a mold, standing and curing; after curing for one day, removing the mold, and performing autoclaved curing on the test block to prepare the foamed concrete test block. According to the method, through cooperative foaming of CO2 and the foaming agent, release of gas is controlled, uniform and stable bubble generation in the concrete is achieved, and the overall mechanical property is improved.
本发明涉及发泡混凝土技术领域，特别涉及一种发泡混凝土及其制备方法，发泡混凝土的制备方法，包括以下步骤：(1)取细骨料和水泥，并搅拌混匀，得到干物料；(2)取稳泡剂和水，向其中通入CO2进行发泡，形成泡沫溶液；(3)向步骤(1)的干物料中加入步骤(2)中得到的泡沫溶液，搅拌混匀后，得到混凝土浆料；(4)按质量比取发泡剂，加入混凝土浆料，搅拌均匀，得发泡混凝土浆料；(5)将发泡混凝土浆料倒入模具中静置固化；固化一天后，拆模，将试块进行蒸压养护，制备得到发泡混凝土试块。该方法通过CO2和发泡剂的协同发泡，控制气体的释放，实现混凝土内部均匀、稳定的气泡生成，提高了整体的力学性能。
