Abstract

The invention discloses a high-toughness waterproof mortar which is prepared from the following raw materials in parts by weight: 140-160 parts of cement, 40-50 parts of silica fume, 2-3 parts of dodecyl trimethyl ammonium chloride, 40-50 parts of bentonite, 40-45 parts of coral powder, 4-6 parts of grease scraps, 2-4 parts of caustic soda flakes, 2-4 parts of rosin, 3-4 parts of sodium pyrophosphate, 4-6 parts of monoethanolamine, a right amount of water, 20-25 parts of auxiliaries, 50-60 parts of sand, 20-25 parts of PVA fiber and 80-100 parts of fly ash. According to the invention, due to use of PVA fiber, the mortar is high in toughness, not easy to crack and high in bonding strength, and has a good bonding performance with brick masonry; due to the utilization of coral powder, bentonite, grease scraps and rosin, the waterproof performance of the mortar is excellent; and by use of auxiliaries, the compressive strength and breaking strength of the mortar are increased, and the workability, sag resistance, thixotropy and anti-settling property of the mortar are improved.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a high-toughness waterproof mortar and a preparation method thereof. Background technique [0002] Mortar is a common material for construction and is an essential material in construction. According to performance, mortar can be divided into many types, such as combined mortar, caulking mortar, thermal insulation mortar, etc.; [0003] At present, the performance and quality of mortar are different, which affects the use. Specifically, the factors that affect the performance of mortar include the workability, fluidity, water retention of freshly mixed mortar, and the strength of hardened mortar. New mortars need to be researched to have excellent construction and processability, sag resistance, thixotropy, anti-settling properties, storage stability, improved pumpability and shear thinning, and new materials need to be found , in order to improve its performance and strength...
