I would like to include the following topic in maintenance of greenery:
Environment friendly concrete
Every 1000 kilograms of cement results in 900 kilograms of CO2.
By substituting some of the cement in the concrete mix with the waste product fly ash , recycled glass and more will reduce carbon footprint upto 25%.This is called environment friendly concrete.
This type of concrete has high durability, the cost of production is quite low and has less consumption of energy as compared to regular cement.
