Waterproof Powder W970​​​​​​​

The real reason of porosity is lack of fillers in concrete which may cause some empty spaces among the sands. This may weak the permeability and reduce the quality of concrete. A permeable concrete is so much weak against penetration of water and destructive ions and then may find a lower durability. In order to fill any empty spaces among sands, waterproof powder is a suitable option. Waterproof Powder is a product based upon fatty acids including fillers and would be moved among the holes and cavities after interaction with resulted compositions out of cement hydration. It plays the role of water/ moisture remover. Impermeability of concrete is one of the important factors for estimation of durability and resistance of concrete. In case of correct combination of concrete with water and cement and excellent stone materials, there will be a reduction in its permeability. Therefore adding controlled amount of waterproof powder may cause a better and denser concrete with considerable reduction in its permeability.​​​​​​​

Consumption method:​​​​​​​

The calculated waterproof powder should be diluted with 2 times of water volume and according to the concrete grade. Diluted ingredient should be added little by little to mixing concrete.
 
It is possible to add the above-mentioned product to the ready concrete and perform concreting after complete mixing. It is suggested to mix the same for totally 2 or 3 minutes.
It is necessary to consume waterproof powder accompanied with water reducers (Concrete lubricants). The best method for adding of waterproof powder is adding the same after mixing of lubricants with concrete.
Then the equal weight of waterproof powder should be deducted from mixing water amount.
It is suggested to continue mixing operations at least for 1 minute for one cubic meter of concrete.

Consumption rate​​​​​​​

Waterproof powder consumption rate depends upon the thickness of concrete. It is usual to use 1-3 percent of consuming cement for the concrete with a thickness of 15cm and 1.5-2 percent of the same for the concrete with a thickness more than 15cm.
 
Note: Any applying more than 3 times of above-mentioned rates without using a lubricant may reduce the concrete resistance as well.
