How should be Water for construction
Water should be free of all contamination when used in construction. Salty water or sea water should never be used for making RCC. It is advisable to use potable/drinkable water, as far as possible.
Addition of excess water is detrimental to concrete. A low water to cement ratio makes the construction strong and durable.
It is always useful to have containers of five or ten liters of water handy while carrying out construction. One bag of cement normally requires 25 liters of water.
Test of Quantity of Water
As a general rule, after mixing the water with cement and other ingredients, a ball of concrete mix should be made. If this ball is thrown up in the air to a height of a meter, it should not break or crumble as this is an indication of excess water content. It would then be advisable to reduce water content in the mix immediately.
