Abstract

The invention discloses a masonry mortar and a preparation method thereof. The masonry mortar comprises following components in parts by weight: 1 to 5 parts of modified waste paper fiber-titanium dioxide composite material with a nano hollow structure, 15 to 55 parts of cement, 30 to 80 parts of graded sand, 0 to 8 parts of mineral admixture, 0.5 to 5 parts of a water-retaining thickening material and 1 to 3 parts of a water reducing agent. The invention also discloses a preparation method of the masonry mortar. Through the crack bridging effect of modified waste paper fibers, early shrinkageis slowed down, and the volume stability is improved. The masonry mortar also has the advantages of light self-weight, excellent impermeability and increased compression-bending ratio, and the toughness of the mortar is improved. Water in the modified waste paper fibers is released, so that hydration of cement in the later period is promoted. In addition, the anti-seepage performance is good, andthe masonry motor also has a soundproof effect.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a masonry mortar with excellent volume stability and a preparation method thereof. Background technique [0002] Building materials not only have a structural role, but also functionality has gradually been recognized by everyone. With the improvement of people's living standards, people's requirements for living places are getting higher and higher. When traditional masonry mortar is used for masonry, people often hear the sound from a distance in the building, especially the sound transmission through the solid building is particularly obvious. It can be seen that the sound insulation effect of traditional buildings is poor, and people are often in intermittent In a noisy environment, the user experience effect is not good. Traditional masonry mortar has large shrinkage and poor volume stability. Studies have found that in addition to absorbing airborn...
