The common reasons for the generation of water secretion in fluid mortar:
From the point of view of the formula and raw materials, the common factors that cause water secretion 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 water secretion 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 water secretion 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 water secretion.
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 water secretion. For example, the sand carries withered leaves, garbage and other debris, which will affect the quality of the mortar, so that the amount of water secretion of the mortar increases.
In general, the reason why the mortar water retention rate is high but more water secretion 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 water secretion. In actual construction, the water retention rate and water secretion amount of mortar should be controlled scientifically and reasonably according to the specific conditions to ensure the stability and reliability of mortar construction quality.
anti-water secretion agent
 SH-W2 (anti-water secretion agent) | SH-W2 is a product with anti-water secretion performance developed to solve the problems of easy water secretion of large flow mortar and easy settlement of sand. It can ensure that the mortar has high fluidity with good uniformity and no water seepage. It has good compatibility with polycarboxylic acid water reducing agent and can effectively make up for the sensitivity of polycarboxylic acid when used together. |
| Appearance | white powder |
| Water content | ≤ 5% |
| 10% liquid pH value (20ºC) | 7±1 |
| Chloride ion content | ≤ 0.06 |
Calculated by the total mass of dry mortar, the addition amount is 0.05-0.3%, please mix well when using to avoid affecting the performance of the product.
(1) It has excellent adaptability, especially suitable for all kinds of cement-based material system.(2) Various cement mortars and high performance concrete
(3) Cement-based self-leveling materials
(4) Various cement concrete precast components and products
(5) Cement-based grouting materials, compression grouting materials, grouting materials and so on
The dosage of SH-W2 is relatively low, pay special attention to the uniformity of defoamer mixing in mortar.
In the process of use, try to avoid direct contact with eyes, skin, etc., recommended the use of protective gloves and goggles, if accidentally stained, please rinse with water.
This product should be stored in the process of moisture-proof treatment..
