The main ingredient in the construction field is water, but generally doesn’t take care of.
The water PPM should be less than 100, as per the coder of the building industry. All Engineers know it, very well. Even the government and PWD buildings are not able to follow this, as therein no extra money paid for softening water.
If the water from bore well of Coimbatore is sent for testing in king institute or water analysis department, then it and comes with a clear certificate that “this water is not suitable for construction.”
Because all waters in Coimbatore are with minimum 300 to 400 PPM in Marudhamalai Road and goes up to 2000 to 3000 PPM in Saravanampatti Area
But almost all constructions are going on with these waters, it will lead to weaken the strength of the materials and concrete, hence corrode easily affects the rods inside. Ultimately, the life of the buildings drops dramatically.
In below to up keep the strength of the building the water should be tested and if needed, it is to be softened before sending for construction.
Water used for mixing and curing shall be clean and free from injurious quantities of alkalis, acids, oils, salts, sugar, organic materials, vegetable growth or other substance that may be deleterious to bricks, stone, concrete or steel. Potable water is generally considered satisfactory for mixing.
(i) Water found satisfactory for mixing is also suitable for curing. However, the water used for curing shall not produce any objectionable stain or unsightly deposit on the surface.
(ii) Sea water shall not be used for mixing or curing.
(iii) Water from each source shall be tested before the commencement of the work and thereafter once in every three months till the completion of the work. In case of ground water, testing shall also be done for different point of drawdown. Water from each source shall be getting tested during the dry season before the monsoon and again after monsoon.
Below 100 ppm (At Coimbatore minimum 300 to 400 PPM in Marudhamalai Road and goes up to 2000 to 3000 PPM on Saravanampati Area .almost all constructions are going on with these waters)
