Mortar waterproof emulsion LH914 is a special emulsion with excellent waterproof performance, especially suitable for JS1 and JS2 waterproof coatings. The emulsion has a good waterproof effect and can effectively prevent moisture from penetrating into the mortar, thereby protecting the building structure from moisture erosion.
1. Causes of mortar bleeding
Mortar bleeding refers to the phenomenon that moisture leaks from the inside of the mortar to the outside during the preparation of the mortar. The bleeding phenomenon is mainly caused by the following reasons:
Quality problems of the mortar itself: Factors such as the materials, mix ratio, and construction methods in the mortar may affect the performance and quality of the mortar. If the materials in the mortar are too loose or the mix ratio is unreasonable, it is easy to cause mortar bleeding.
Influence of the external environment: During the mortar construction process, the temperature, humidity, wind speed and other factors of the surrounding environment may affect the evaporation and penetration rate of the mortar. If the ambient humidity is high or the temperature is low, it is easy to cause mortar bleeding.
Improper construction method: During the mortar construction process, the technical level and construction method of the construction workers will also affect the quality of the mortar. For example, excessive mixing or adding too much water will cause excessive moisture in the mortar, which is easy to bleed.
2. Problems caused by mortar bleeding
Bleeding has an adverse effect on the performance of mortar, which is mainly reflected in the following aspects:
Reduced strength: The greater the bleeding rate, the lower the strength of the mortar.
Decrease in impermeability: Bleeding will cause the impermeability of the mortar to decrease, thereby affecting its waterproof effect.
Affecting construction quality: Bleeding may cause the mortar surface to be uneven, affecting the aesthetics and construction quality.
3.How to prevent mortar bleeding
In order to prevent mortar bleeding, the following measures can be taken:
Choose a suitable mix ratio: According to construction needs and environmental conditions, choose a suitable mortar mix ratio to avoid using mortar that is too dry or too wet.
Increase water reducer: Adding a proper amount of water reducer can effectively reduce the cement content of cement mortar, improve the fluidity of cement, and reduce the phenomenon of cement mortar bleeding.
Improve environmental humidity: During construction, the environmental humidity and temperature should be reasonably controlled, and indoor air circulation should be maintained to prevent water accumulation on the surface of cement mortar.
Use waterproofing agent: Before mortar construction, a layer of waterproofing agent (such as LH914 waterproof emulsion) can be applied on the mortar surface to prevent moisture from penetrating into the mortar.
Control construction methods: Strengthen construction management to ensure that construction workers perform construction in accordance with specifications and avoid problems such as excessive mixing or excessive water addition.
