With the continuous development of science and technology, the construction industry has become easier and simpler. Various building materials full of scientific and technological content are increasingly used in engineering. Mortar admixture is one of them.
Mortar admixtures have created huge value for buildings in all walks of life. So what types of mortar admixtures are there? Improve the building effect during the construction process. Create huge value for buildings in all walks of life.
Mortar admixtures are a series. There are many types of them. Different types of mortar admixtures have different functional focuses. The scope of use is also different.
For example, wet-mixed mortar admixtures are an admixture with super plastic preservation effects. It can ensure that the construction time of wet-mixed mortar is adjusted within 1 to 2 days. It can meet the storage for a long time on the construction site. It effectively ensures that there will be no stratification and water seepage during mortar construction. It can solve common quality problems such as hollowing and cracking in construction.

Construction method:

Mortar admixtures are mixed with cement and aggregates, and the general dosage is 0.05%-0.2% of the cement dosage. Mortar mixing is generally based on mechanical mixing.
If a vertical mixer or horizontal mixer is used, it is necessary to first add some sand, agent, and water to mix thoroughly before adding all the cement and sand for mixing.
For a drum mixer, add the agent to cement and sand and mix them dry for 1 minute. Then add enough water and mix for 3-5 minutes. If mixed manually, the amount of admixture should be doubled during the first mixing.

Precautions:

1. Mortar admixtures should be stored in a dry and ventilated place, and moisture-proof should be paid attention to during storage and transportation.
2. When building walls, water and electricity pre-embedding work needs to be done well.
3. During construction in cold winter and rainy seasons, due to the high water retention of mortar, brickwork is not easy to absorb moisture. During masonry, bricks should be wet with appropriate amount of water.
4. Plastering should be cured twice when priming. The second plastering can only be carried out after the first plastering mortar solidifies.
