Color ready-mixed mortar and production method thereof

Abstract

The invention relates to colored premixed mortar and a production method of the colored premixed mortar. The colored premixed mortar is characterized by comprising the following raw materials in parts by weight: 60-70 parts of artificial sand, 12-13 parts of cement, 10-12 parts of class II pulverized fuel ash, 1-5 parts of an inorganic pigment and 0.1-0.5 part of additives. The colored premixed mortar disclosed by the invention has excellent stain resistance, stability, mechanical performance and anti-aging performance, and can not cause saltpetering and chromatic aberration phenomena; meanwhile, the colored premixed mortar has good tensile adhesive strength, compressive strength, anti-permeability, crack resistance, shrinkage-reducing performance, water-retention rate and other properties, and also has excellent working performance and construction properties such as easiness in pumping, easiness in compacting and the like.

Description

technical field

[0001] The invention belongs to the processing field of ready-mixed mortar, and in particular relates to a colored ready-mixed mortar which has no efflorescence and color difference during use and has excellent stain resistance and a production method thereof. Background technique

[0002] 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 mortar used in masonry and plastering construction is still mainly cement mortar or mixed mortar.

[0003] With the technological progress of the construction industry and the improvement of civilized construction requirements, the on-site mixed mortar has increasingly shown its inherent defects, such as unstable mortar quality, large waste of materials, single type of mortar, low deg...
