Principle and concept of water-proof cement
Water-proof cement is a cement with a details waterproofing representative added. Its major feature is to improve the thickness and impermeability of cement by changing the microstructure of concrete and decreasing the number and dimension of capillary pores. Typically, water-proof cement will certainly add water-proof products such as salt silicate and potassium silicate during the production process. These materials will create a water-insoluble crystal in the hydration reaction, filling the pores in the cement and making it waterproof.
Advantages and downsides of water resistant cement
Benefits
Hassle-free construction: Making use of waterproof concrete is similar to that of common cement, and no additional specialist skills are needed.
Low cost: Compared to other premium water resistant products, the cost of water-proof concrete is much more budget friendly and appropriate for large water resistant tasks.
Good longevity: The waterproof concrete layer, after appropriate construction, can maintain its waterproofness for a very long time and is not easy to age.
Commonly utilized: Appropriate for cellars, roofs, commodes, pool and other scenes.
Negative aspects
Limitations: Water-proof cement is generally utilized for mild to moderate water infiltration problems. For extreme water stress and lasting immersion atmospheres, the effect may not be comparable to expert waterproof layers.
High building demands: Building needs to be executed purely according to the directions otherwise the expected effect might not be achieved.
High maintenance needs: Once the water resistant layer is damaged, repair work is much more complicated.
