Abstract

The invention discloses a production method of southern inner wall cement mortar. The southern inner wall cement mortar comprises the following raw materials: sand aggregate, quick hardening sulphoaluminate cement, fly ash, a composite coupling agent, dispersible latex powder, cellulose ether, starch ether, a water reducing agent, anti-crack fiber and an air entraining agent. The production methodprovided by the invention improves a defect of inherent hard brittleness of mortar, improves crack resistance and leakage resistance of the mortar, reduces hollowing, increases adhesive force and thelike, so that the mortar is more suitable for mechanized construction, and has the advantages of small addition amount and high cost performance; the strength of the mortar is improved; the problemsof dryness, difficult batch scraping, low bonding strength, easy appearance of hollowing, falling-off, large shrinkage, easy surface cracking of the mortar are solved; and the frost resistance, the impermeability and the water resistance of the mortar are improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production method of southern interior wall cement mortar. Background technique [0002] The four seasons in southern my country (including Guangdong, Guangxi, Guizhou, Fujian, Jiangxi, Yunnan and other provinces) are not very distinct. After the beginning of spring, the temperature begins to rise, and it will be humid and humid. There will be more and more humid days in the south, and the humidity will be heavy. After the cold spring, it will basically not It's cold, summer comes early, the sun is particularly harsh, and the rainfall in summer is abundant, so floods often occur in the south in summer. [0003] "Returning to the south" is a phenomenon of weather returning to humidity, which generally occurs during February to April in spring, mainly because after the cold air leaves, the warm and humid air quickly counterattacks, causing the temperature to rise and th...
