Abstract

The invention discloses a production method of high-strength non-vibrated environmental-friendly smooth facing fabricated part mortar. Raw materials of the high-strength non-vibrated environmental-friendly smooth facing fabricated part mortar comprises limestone machine-made sand, limestone powder, early-strength sulphoaluminate cement, ordinary silicate cement, composite coupling agent, water reducing agent, dispersible emulsion powder, cellulose ether, starch ether, sodium tetraborate, lithium carbonate, antifoaming agent and high-strength fiber. According to the production method, the intrinsic defect of the crisp and hard performance of the mortar is overcome, the anti-cracking and anti-leakage performance of the mortar is improved, hollowing is reduced, the bonding force is improved,the mortar is more suitable for mechanical construction and has the advantages of low addition amount and high cost performance, and the rigidity of the mortar is improved; the problems are solved that the mortar is dry and is not easily scraped, the bonding strength is low, hollowing and falling phenomena are easily caused, the shrinkage amount is large, and the surface is easily cracked; the anti-freezing, anti-leakage and water-resistant performance of the mortar is improved, and the mortar has the advantages of being high in compressive strength, fracture resistance and leakage resistance,high in strength, non-vibrated, environmentally friendly and smooth.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production method of high-strength anti-vibration, environment-friendly and smooth veneer prefabricated mortar. Background technique [0002] Mortar, the bonding substance used in building bricks, is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) plus water, also called mortar, and also used as mortar. Mortar is made by mixing cementitious materials (cement, lime, clay, etc.) and fine aggregate (sand) with water. Commonly used are cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar. [0003] Mortar is one of the most widely used building materials in construction engineering, and it is widely used in masonry and plastering of buildings. In my country's current construction projects, more than 60% of buildings still use wall materials such as bricks and blocks, and the construction morta...
