Abstract

The invention relates to mortar thickening powder and a preparation method and application thereof. The mortar thickening powder comprises the following components in part by weight: 92 to 96 parts of metallic magnesium slag powder, 2.0 to 3.0 parts of anhydrite powder, 1.0 to 2.5 parts of re-dispersible latex powder and 1.0 to 2.5 parts of hydroxypropyl methyl cellulose. The mortar thickening powder belongs to an organic-inorganic composite ecological powder preparation, and has the advantages of simplicity in production, non-toxicity and innocuousness; and the mortar prepared by adopting the mortar thickening powder has good workability and adhesive aggregation performance, and overcomes the defects of sand formation, hollowing, cracking, loosening and the like of the conventional mortar.

Description

technical field [0001] The invention relates to a mortar thickening powder, in particular to a dry powder plastering mortar for construction and a mortar thickening powder used in masonry mortar, which belongs to the field of building mortar. Background technique [0002] Mixed mortars have been used in construction projects for a long time. Due to a series of factors such as defects in raw materials and inaccurate measurement of this traditional construction lime mortar, the quality of construction mortar is poor, resulting in many engineering quality problems, and it also pollutes the environment and affects civilized construction. With the development of construction technology, the construction industry has also begun to use mortar admixtures in recent years, which has played a certain role in improving the workability of construction mortar. However, through investigation and research, it is found that the effect of the construction mortar admixture is not ideal after ...
