Abstract

The invention discloses an anti-cracking and anti-seepage building mortar and a preparation method and an application thereof. The anti-cracking and anti-seepage building mortar comprises the following raw materials in parts by weight: 35 to 60 parts of cement, 50 to 75 parts of waste tile powder, 13 to 17 parts of dibutyltin maleate, 8 to 15 parts of sodium metavanadate, and 5 to 11 parts of tripolyglycerol monostearates. The anti-cracking and anti-seepage building mortar of the invention has better impermeability, heat preservation, water retention and crack resistance, improves the strengthof the wall, and significantly improves the construction quality of the building. The preparation process of the anti-crack and anti-seepage building mortar of the invention is simple and easy to realize, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the field of construction, in particular to an anti-crack and anti-seepage construction mortar and its preparation method and application. Background technique [0002] Construction mortar is a mortar that bonds masonry block materials (bricks, stones, blocks) into a whole. With the development of society and the continuous progress of the construction industry, the mortar made of natural river sand is gradually replaced by artificial mortar. And artificial mortar is gradually developing towards a more environmentally friendly and energy-saving direction. However, the existing people have the following defects in the use of mortar: the joint between the mortar and the masonry block material is unevenly distributed with high stress, and because the stress is in a state of thermodynamic imbalance, it is easy to cause cracks and cracks in the wall. water seepage etc. Therefore, the present invention provides an anti-crack and a...
