Application of limestone ultrafine powder in gypsum-based self-leveling mortar and gypsum-based self-leveling mortar
The invention discloses application of limestone ultrafine powder in gypsum-based self-leveling mortar and the gypsum-based self-leveling mortar. The gypsum-based self-leveling mortar is prepared from the following raw materials in parts by weight: 700 parts of gypsum, 10 parts of sulphoaluminate cement, 150 parts of limestone ultrafine powder, 140 parts of quartz sand, 5 parts of a suspension stabilizer, 3 parts of a polycarboxylate superplasticizer, 1.5 parts of a defoaming agent, 2 parts of cellulose and 1.5 parts of a gypsum retarder. The ground constructed by gypsum-based self-leveling is accurate in size, extremely high in levelness and free of hollowing and cracking; operation is easy and convenient, and efficiency is high; the phenomena of cracking, bulging and the like caused by thermal expansion and cold contraction like a cement mortar layer are avoided; the gypsum-based self-leveling hardened floor has certain elasticity, feet feel warm and comfortable, and the gypsum-based self-leveling hardened floor has a certain sound insulation effect. The self-leveling gypsum popularized and applied in the building material market in China is small in resistance and wide in prospect.
本发明公开了石灰石超细粉在石膏基自流平砂浆的应用及石膏基自流平砂浆。该石膏基自流平砂浆，由以下重量份数的原料制备而成：石膏700份、硫铝酸盐水泥10份、石灰石超细粉150份、石英砂140份、悬浮稳定剂5份、聚羧酸减水剂3份、消泡剂1.5份、纤维素2份、石膏缓凝剂1.5份。本发明采用石膏基自流平施工的地面，尺寸准确，水平度极高，不空鼓、不开裂；作业时轻松方便，效率高；不会像水泥砂浆层那样，因热胀冷缩产生开裂、起鼓等现象；石膏基自流平硬化后的地板有一定弹性，脚感温暖舒适：并且具有一定的隔音效果。在我国建材市场推广应用自流平石膏的阻力小，前景大。
