Green concrete means consuming waste material in concrete and reducing the emission of CO2 gas.

Concrete becomes green when we add products like flyash and reduce the consumption of cement (which become national saving). flyash reacts with CO2 produce during hydration for secondary hydration process which reduces the CO2 which is released.

Any product which reduces CO2 emission is Green product.

This is done in the interest to reduce the global warming and keep planet healthy.
 
But during slab concrete and after doing for curing only 7 days taken, it changes it colour to green.why?
And also don't immersed slab for 10 to 14 days while curing. Can it also leakage the slab?
In study period we done curing 28 days for cube with no steel.but in concrete steel also present.should it rust?
