Method for preparing foam concrete by using carbon dioxide foam
The invention relates to the technical field of concrete, in particular to a method for preparing foam concrete by using carbon dioxide foam, which comprises the following steps: preparing super-stable carbon dioxide foam: uniformly dispersing nano-particles in water to prepare nano-particle turbid liquid; adding a surfactant into the nanoparticle suspension and uniformly stirring to obtain a nanoparticle foaming agent; the foaming machine sucks a nanoparticle foaming agent, and carbon dioxide is introduced to prepare stable carbon dioxide foam; the preparation method comprises the following steps: adding water and a water reducing agent into cement, uniformly stirring to obtain cement paste, and introducing carbon dioxide gas into the cement paste to obtain carbonized cement paste; and adding a foam stabilizer and the prepared carbon dioxide foam into the carbonized cement paste, and continuously stirring until the carbon dioxide foam completely enters the cement paste. Under the condition that the strength of the prepared foam concrete is not changed, the density is at least one third lower than that of an existing mode, and the application scenarios of the foam concrete are increased.
本发明涉及混凝土技术领域，具体涉及一种使用二氧化碳泡沫制备泡沫混凝土的方法，包括：制定超稳定二氧化碳泡沫：将纳米颗粒均匀分散在水中，制成纳米颗粒悬浊液；在纳米颗粒悬浊液中加入表面活性剂并搅拌均匀，制得纳米颗粒发泡剂；发泡机吸入纳米颗粒发泡剂，通入二氧化碳制备稳定的二氧化碳泡沫；向水泥中加入水和减水剂搅拌均匀得到水泥浆体，向水泥浆体中通入二氧化碳气体，得到碳化水泥浆；向碳化水泥浆中加入稳泡剂与制得的二氧化碳泡沫并持续搅拌，直至二氧化碳泡沫全部进入水泥浆中。本发明制备的泡沫混凝土在强度不变的情况下，密度比现有方式低至少三分之一，使得泡沫混凝土的应用场景得以增加。
