Foamed gypsum block and preparation method thereof
The invention relates to a foamed gypsum block and a preparation method thereof. The preparation method comprises the following steps of (1) mixing mixed-phase gypsum powder with cement and an additive to prepare mixed gypsum powder; (2) mixing a surfactant and a stabilizer into a composite foaming agent; (3) uniformly stirring and mixing the mixed gypsum powder and water to prepare gypsum slurry,and adding water into the foaming agent to be stirred to form foam; (4) mixing the gypsum slurry and the foam to prepare foaming slurry; (5) pouring the foaming slurry into a building block mold, conducting initial curing on a pouring body in the mold until the compressive strength is not smaller than 2 MPa, and conducting demolding; (6) cutting the demolded casting body into the building block by using a band saw; and (7) conducting natural curing. According to the gypsum solid building block, the indexes such as the block size, strength and single block quality are basically the same as those of traditionally used aerated concrete, the gypsum solid building block can be constructed by adopting a construction method of a traditional aerated concrete building block, no special requirements for skills of workers exist, and the gypsum solid building block has a wide market prospect.
本发明涉及一种发泡石膏砌块及其制备方法。所述制备方法为：(1)将混合相石膏粉与水泥、外加剂混合制成混合石膏粉；(2)将表面活性剂、稳定剂混合成复合发泡剂；(3)将混合石膏粉与水搅拌混合均匀，制得石膏浆料；将发泡剂加水搅拌形成泡沫；(4)将石膏浆料、泡沫混合制成发泡浆料；(5)将发泡浆料浇筑进砌块模具中，浇筑体在模具中初期养护至抗压强度不小于2MPa进行脱模；(6)脱模后的浇筑体用带锯进行切割成砌块；(7)自然养护。本发明提供的石膏实心砌块，块型尺寸、强度、单块质量等指标与传统使用的加气混凝土基本相同，可采用传统加气混凝土砌块的施工方法来施工，对工人技能没有特别要求，具有广泛的市场情景。
