Masonry mortar production process

Abstract

The invention discloses a masonry mortar production process, and relates to the field of masonry mortar preparation; raw materials and auxiliary materials comprise dried fine sand, cement, talcum powder, hydroxypropyl methyl cellulose, dispersible latex powder, hydroxypropyl starch and a bonding auxiliary agent; the dried fine sand is river sand with the particle size of 70-120 meshes and has the mass of 480 kg-500 kg; the cement is Portland cement 42R5 and the mass of 270 kg-300 kg; the talcum powder is heavy calcium carbonate and has the mass of 190 kg-200 kg; the hydroxypropyl methyl cellulose has the viscosity of 190,000-200,000 and the mass of 2.2 kg-2.5 kg; the dispersible latex powder has the mass of 3.8 kg-4 kg; the hydroxypropyl starch has the mass of 0.4 kg-0.5 kg; and the bonding auxiliary agent has the mass of 1.9 kg-2 kg. The mortar has high water-retaining property and good construction workability, can effectively meet the thin-layer construction requirement of the mortar, has high tensile strength with an ALC plate and good wall structure stability, improves the mechanical construction performance of the mortar, and solves the problems of difficulty in sizing, cracking and hollowing in the construction of the ALC plate; and slurry on a masonry surface is uniformly coated, the masonry quality is ensured, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of masonry mortar preparation, in particular to a production process of masonry mortar. Background technique [0002] Masonry mortar refers to the mortar that bricks, stones, blocks and other blocks are built into masonry. It plays the role of bonding, lining and force transmission, and is an important part of masonry. Therefore, in the masonry construction process, the strength of the masonry mortar determines the quality of the masonry. The masonry mortar prepared by the existing masonry mortar preparation method has poor workability and poor water retention, and cannot meet the quality requirements of masonry construction. Contents of the invention [0003] The purpose of the present invention is to provide a kind of masonry mortar production process, this mortar has higher water retention property and better construction workability, can effectively meet the construction requirement of mortar thin layer, and th...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of masonry mortar production process, this mortar has higher water retention property and better construction workability, can effectively meet the construction requirement of mortar thin layer, and the tensile strength of ALC sheet material is relatively high. High, the stability of the wall structure is good, the mechanical construction performance of the mortar is improved, and the problems of difficulty in sizing, cracking and hollowing in the construction of ALC panels are solved, and the slurry on the masonry surface is evenly applied, which ensures the quality of the masonry and greatly improves the construction efficiency.
