Problems solved by technology

At present, the quality of brickwork projects generally has the following main problems: 1. The strength of sand is unstable and the variety is mixed. Mortar is one of the components of masonry in masonry. The strength of mortar is unstable, which has a great relationship with the bearing capacity of masonry. , does not guarantee the overall performance of the wall, compressive strength, and stiffness
2. The workability of mortar is poor, and the bottom sinks hard, which is mainly manifested in the inconsistent consistency and water retention of the mortar, which is prone to sedimentation and bleeding on the site, and it is difficult to spread and squeeze, which affects the quality of masonry.
3. The bonding strength of the mortar is not enough, because the mortar forms a whole with the base, such as the plastering mortar and the wall material bonded together to form a wall, and the ground mortar and the floor are bonded together to form a floor. The mortar is directly used for bonding, such as masonry mortar is to bond various bricks, blocks, etc. into a whole, etc., so the bond strength is a very important performance of mortar
Insufficient bonding strength will lead to hollowing, cracking and falling off of masonry

Abstract

The invention relates to building block ready-mixed mortar and a production method thereof. The building block ready-mixed 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 grade II coal fly ash, 0.5-1 part of cold soluble polyvinyl alcohol powder and 0.1-0.5 part of additive. The building block ready-mixed mortar provided by the invention can significantly improve adhesion, tensile adhesive strength, compressive strength, impermeability, anti-crack property, shrinkage reduction, water retention rate and other performances of building blocks and simultaneously has excellent working performances and other excellent construction performances and is easy for pumping and compacting.

Description

technical field [0001] The invention belongs to the processing field of ready-mixed mortar, in particular to a kind of ready-mixed mortar which can be widely used in building blocks 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 degree of civilized construction, and environmental pollution. T...
