Application of ash calcium powder, and anti-crack gypsum mortar
The invention discloses application of ash calcium powder, and anti-crack gypsum mortar. The application of the ash calcium powder is that the ash calcium powder is used as an anti-cracking componentof gypsum mortar, wherein the setting time of the gypsum mortar is more than or equal to 30 minutes, and the mass ratio of the use amount of the ash calcium powder to the use amount of the semi-hydrated gypsum powder in the gypsum mortar raw material is (0.05-5.0):100. The invention further provides anti-crack gypsum mortar, which comprises ash calcium powder, semi-hydrated gypsum powder and a gypsum retarder, wherein the use amount of the retarder enables the setting time of the gypsum mortar to be longer than or equal to 30 min. In the gypsum mortar disclosed by the invention, the ash calcium powder can adsorb free water in the gypsum mortar and enable the surface bleeding rate to be greater than the evaporation rate, so that an anti-cracking effect is achieved, and plastic cracking of the gypsum mortar can be effectively inhibited.
本发明公开了灰钙粉的应用和一种抗裂石膏砂浆。所述灰钙粉的应用，是用于作为石膏砂浆的抗裂组分；所述石膏砂浆的凝结时间≥30min，所述灰钙粉的用量与所述石膏砂浆原料中的半水石膏粉的用量的质量比为（0.05‑5.0）:100。本发明还提供一种抗裂石膏砂浆，其组成原料包括灰钙粉、半水石膏粉和石膏缓凝剂，所述缓凝剂用量使石膏砂浆的凝结时间≥30min即可。本发明所述的石膏砂浆中，灰钙粉能够吸附石膏砂浆中的游离水并且使得表面泌水速率大于蒸发速率，起到抗裂的作用，可有效抑制石膏砂浆塑性开裂。
