Idea and principle of water resistant concrete
Waterproof cement is a cement with a particular waterproofing agent added. Its major feature is to improve the thickness and impermeability of cement by changing the microstructure of cement and minimizing the number and size of capillary pores. Generally, water-proof cement will certainly add waterproof products such as sodium silicate and potassium silicate during the production process. These materials will certainly form a water-insoluble crystal in the hydration reaction, loading the pores in the concrete and making it water-proof.
Benefits and drawbacks of water-proof cement
Advantages
Convenient construction: Making use of water-proof cement resembles that of normal cement, and no extra professional skills are called for.
Inexpensive: Compared to other premium water-proof products, the price of waterproof concrete is more cost effective and appropriate for large water resistant tasks.
Good sturdiness: The waterproof concrete layer, after proper building, can maintain its waterproofness for a long period of time and is challenging to age.
Commonly used: Ideal for basements, roofing systems, commodes, swimming pools and various other scenes.
Negative aspects
Limitations: Water resistant cement is primarily utilized for mild to moderate water infiltration problems. For severe water stress and lasting immersion atmospheres, the impact may not be as good as expert water-proof coatings.
High construction needs: Construction should be carried out strictly according to the instructions otherwise the predicted effect might not be achieved.
High maintenance demands: Once the water resistant layer is damaged, repair work is more difficult.
