SH-W2 Anti-Bleeding and Anti-Segregation Additive for Cement Self-Leveling Mortar

Product Description

Product Description

The common reasons for the generation of bleeding in fluid mortar:
From the point of view of the formula and raw materials, the common factors that cause bleeding and settlement, mainly including the following aspects:
1, improper use of water retention agent
Water retention agent is a commonly used additive in mortar, which can effectively improve the water retention rate of mortar. However, if it is used improperly, it will lead to an increase in the water retention rate of mortar, but the amount of bleeding will also increase.

2,unreasonable water-cement ratio
When making mortar, the setting of water-cement ratio affects the performance and quality of mortar. If the water-cement ratio is set too high, the water retention rate of mortar will increase, but the amount of bleeding will also increase.

3, temperature, humidity and other factors affect
In some temperature and humidity environment, the water of the mortar will be easier to volatilize, which will lead to an increase in the amount of bleeding.

4,sand, water and other materials of poor quality
If the quality of sand and water in mortar is poor, it will also lead to high water retention but more bleeding. For example, the sand carries withered leaves, garbage and other debris, which will affect the quality of the mortar, so that the amount of bleeding of the mortar increases.
In general, the reason why the mortar water retention rate is high but more bleeding is more complicated, in addition to the above factors, the technical level of the construction personnel and the operation process, will also have an important impact on the control of mortar bleeding. In actual construction, the water retention rate and bleeding amount of mortar should be controlled scientifically and reasonably according to the specific conditions to ensure the stability and reliability of mortar construction quality.
 

SH-W2
anti-bleeding and anti-segregation agent

SH-W2 (anti-bleeding and anti-segregation agent)

SH-W2 is a product with anti-bleeding and anti-segregation performance developed to solve the problems of easy bleeding of large flow mortar and easy settlement of sand. It can ensure that the mortar has high fluidity with good uniformity and reduced bleeding and improved segregation resistance. It has good compatibility with polycarboxylic acid water reducing agent and can effectively make up for the sensitivity of polycarboxylic acid when used together.
