Is waterproof cement really waterproof? nano metal powder
Idea and principle of water resistant concrete
Waterproof cement is a cement with a certain waterproofing representative included. Its primary feature is to improve the thickness and impermeability of concrete by changing the microstructure of concrete and reducing the number and size of capillary pores. Typically, water resistant cement will add waterproof products such as sodium silicate and potassium silicate during the manufacturing process. These materials will certainly develop a water-insoluble crystal in the hydration response, filling the pores in the concrete and making it water-proof.

Advantages and disadvantages of water resistant cement
Benefits
Practical building and construction: Using water resistant cement is similar to that of regular concrete, and no extra professional abilities are called for.
Affordable: Compared with other high-end waterproof materials, the price of water resistant cement is more economical and ideal for massive water-proof tasks.
Excellent toughness: The water-proof cement layer, after appropriate building and construction, can maintain its waterproofness for a long period of time and is challenging to age.
Commonly used: Ideal for cellars, roof coverings, toilets, pool and other scenes.
Downsides
Limitations: Waterproof cement is generally made use of for moderate to modest water seepage troubles. For extreme water stress and long-term immersion environments, the impact might not be as good as specialist water resistant coatings.
High building and construction demands: Construction needs to be performed strictly based on the instructions otherwise the predicted effect may not be achieved.
High maintenance needs: Once the water resistant layer is damaged, repair is much more complicated.
