Water proofing liquid admixtures are usually water reducing agents or plasticisers which help the cement mortar or concrete to be pliable and dense.
Why use?
When the quantity of water is reduced, the resulting cured cement mixture is less porous and hence dense after the water has been absorbed by the cement or has evaporated. This greatly reduces capillary formation in the mixture which is the main cause of water absorbtion leading to leakage.
Dense concrete also does not allow atmospheric gases such as sulhpur-dioxide, carbon-dioxide and chlorides to be absorbed by the structure thus preventing carbonation and corrosion of steel rebars. Corroded rebars not only lose strength, but also increase in volume (rust takes up almost 10 times more volume than steel) and lead to cracks in concrete and eventually spalling. (See this article for repairs of spalled concrete)
Admixtures also improve workability of the mixture. Concrete can be cast easily, without leaving voids, due to better fluidity. Plaster shows lower rebound loss, when it is thrown onto walls and ceilings due to better adhesion. Increased cohesive property of concrete / mortars eliminates segregation and bleeding.
They also reduce shrinkage cracks in concrete and plasters
A small quantity of inexpensive admixtures go a long way in improving the performance of your cement mixtures. An investment worth every rupee.
Instructions
. Add the recommended dosage of admixture to the water for the mixture and mix thoroughly. Excess dosage can lead to reduction in strength of cement mixture.
. Ideally water must not exceed 28ltr per 50kg bag of cement.
. Add the water to the cement mixture. Mix thoroughly.
