Concept and principle of water resistant concrete
Water resistant cement is a concrete with a certain waterproofing representative added. Its main feature is to enhance the thickness and impermeability of cement by transforming the microstructure of cement and reducing the number and dimension of capillary pores. Usually, water-proof cement will certainly add water resistant materials such as salt silicate and potassium silicate throughout the production process. These products will certainly develop a water-insoluble crystal in the hydration reaction, filling up the pores in the concrete and making it water resistant.
Advantages and drawbacks of water resistant concrete
Benefits
Practical building and construction: Making use of waterproof cement resembles that of average concrete, and no extra professional abilities are required.
Inexpensive: Compared with other premium waterproof products, the price of water-proof concrete is much more budget friendly and suitable for large waterproof tasks.
Good longevity: The water-proof cement layer, after appropriate construction, can preserve its waterproofness for a long time and is difficult to age.
Widely used: Ideal for basements, roofs, commodes, pool and various other scenes.
Downsides
Limitations: Waterproof cement is generally made use of for light to modest water seepage issues. For extreme water stress and long-lasting immersion environments, the effect might not be just as good as specialist water resistant coatings.
High construction demands: Construction must be carried out purely based on the instructions otherwise the predicted impact might not be attained.
High maintenance needs: Once the water resistant layer is harmed, fixing is extra complicated.
