Problems solved by technology

However, in coastal areas, especially in northern coastal areas, due to special climate factors, large temperature differences, strong and changeable winds, and humid air (high concentration of potassium, sodium, and chloride ions in sea breeze and seawater), conventional plastering mortar is used for construction Finally, the water retention and air permeability of the surface of the wall is poor, and the wall is easy to crack and peel off, resulting in mildew on the inner surface of the wall, which not only pollutes the environment, endangers personal health, reduces the strength of the wall, but also affects the appearance of the interior, which brings great harm to people's lives. to great trouble

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a plastering mortar and a preparation method thereof. Background technique [0002] Mortar is a commonly used building material, generally used in masonry and plastering works. Mortar is made by mixing cementitious materials (cement, lime, clay, etc.) and fine aggregate (sand) with water. According to the composition materials, it can be divided into: ①Gypsum mortar: made of lime paste, sand and water according to a certain ratio, generally used for masonry and plastering layers that do not require high strength and are not subject to moisture; ②Cement mortar: made of Cement, sand and water are made according to a certain ratio, and are generally used for masonry, walls or floors in wet environments or in water; ③Mixed mortar: Add appropriate admixtures such as fly ash, It is made of diatomite to save the amount of cement or lime and improve the workability of mortar...
