摘要
粉刷石膏是一种优良的内墙装饰材料,但在使用过程中要注意原材料的质量控制和周围环境的温度湿度控制。本文针对某大学生公寓粉刷石膏的开裂进行了系统分析,主要包括石膏中含量超标的无机盐重结晶和未水化石膏颗粒的延迟水化等原因。
Rendering plaster is one of the excellent indoor decorative materials.However,it is very important for plaster application to control the quality of the raw material and the humidity and temperature of construction ambiance.In this paper,the plaster crack is particularly studied based on a university student hostel project.It is found that the main reasons caused plaster crack include the soluble salt crystallization,the delayed hydration of relict hemihydrate and the dehydration of gypsum.
