Building mortar admixture
The invention discloses a building mortar admixture which includes following components, by weight, 80-100 parts of a naphthalene sulfonic acid/formaldehyde, 140-180 parts of molasses calcium, 25-30 parts of methyl cellulose ether, 20-32 parts of sodium dodecyl benzene sulfonate, 80-100 parts of mineral powder and 40-80 parts of bentonite. The raw materials are added successively into a reactor in order and then are subjected to mechanical stirring and mixing to obtain the admixture. The admixture is used for masonry mortar, plastering mortar and decorative mortar, can reduce usage amount of water and cement in the mortar, can improve strength and durability, can reduce the use quantity of cement, can reduce shrinkage rate and cracking damage.
