Concept and principle of waterproof cement
Water resistant cement is a cement with a particular waterproofing agent included. Its primary function is to enhance the thickness and impermeability of concrete by altering the microstructure of concrete and reducing the number and size of capillary pores. Usually, waterproof cement will add water-proof products such as sodium silicate and potassium silicate throughout the manufacturing process. These materials will certainly develop a water-insoluble crystal in the hydration response, loading the pores in the cement and making it waterproof.

Advantages and disadvantages of water-proof concrete
Advantages
Practical building and construction: Using water resistant concrete resembles that of ordinary concrete, and no additional expert abilities are called for.
Affordable: Compared with various other premium waterproof products, the price of water-proof cement is more economical and ideal for massive waterproof jobs.
Great resilience: The water-proof cement layer, after proper construction, can maintain its waterproofness for a long period of time and is difficult to age.
Extensively utilized: Ideal for basements, roofings, bathrooms, swimming pools and other scenes.
Drawbacks
Limitations: Waterproof cement is mostly made use of for moderate to moderate water seepage problems. For serious water pressure and long-term immersion environments, the impact might not be just as good as expert waterproof coatings.
High construction demands: Building and construction has to be accomplished strictly in accordance with the guidelines otherwise the expected effect may not be accomplished.
High maintenance demands: Once the water-proof layer is damaged, fixing is extra challenging.
