What are the differences between cement mortar and mixed mortar?

Probably many people are interested in The difference between life is not very clear. It’s okay not to know the difference between cement mortar and mixed mortar because in the editor below we will introduce some details to tell you the difference between cement mortar and mixed mortar so that You can learn the difference between cement mortar and mixed mortar connections.

The difference between cement mortar and mixed mortar:

1. Mixed mortar is usually made of cement and lime mortar, and is usually used for masonry on the ground. Adding lime mortar to the mixed mortar improves the strength of the mortar. Workability, more convenient operation, which is beneficial to improving the density and work efficiency of masonry. Cement mortar is composed of cement, medium sand and water, and the price is related to the material ratio.

2. Cement mortar is easy to crack, which is one of the reasons why mixed mortar is used instead of cement mortar for interior wall plastering. In addition, from the appearance point of view, pay attention to the water retention of the mortar during transportation. The water retention performance of cement mortar is not as good as that of mixed mortar. During the bumpy transportation process, there is a layer of water on the surface of the cement mortar (serious cases can also be seen in low grades). mixed sand), and the workability and water retention of mixed mortar are worse than cement mortar.

3. Mixed mortar: After adding lime mortar, the masonry mortar has better workability and water retention than cement mortar. It is easy to construct and saves cement, but the strength is reduced and the waterproof and moisture-proof performance is poor. It is usually used for moisture-proofing above +-0.000 part.

4. Cement mortar: mainly used in basements, foundations, water conservancy projects and other wet parts. Same grade The strength of cement mortar is higher than that of mixed mortar, so it is stipulated that cement mortar should be used as the corner protection of door and window openings.

5. In construction projects, cement mortar is first used as foundation and wall masonry, and also Used as a binder for masonry materials before being used for indoor and outdoor painting. The proportions of cement mortar used for different purposes will be different. Usually, this is to ensure the sand diameter, moisture content and actual strength of the cement mortar.

6. Mixed cement mortar is made by adding lime, clay and other additives on the basis of cement mortar. Mixed cement mortar has strong plasticity and is easy to operate. Cement mortar has one less ash than mixed mortar and has lower strength. high.

7. In other words, the workability of mixed mortar is the best, and the durability of cement mortar is the best. Lime mortar is often used for decoration, mixed mortar is also mixed with other materials such as lime mortar that have good masonry properties and is often used in brickwork above the “damp proof course” of a wall. Cement mortar has good masonry properties Damp proof properties, typically used for plastering walls below the “damp proof course” of masonry and wall foundations. </p
