Green mix concrete
is blend of recycled aggregate, sand, fly ash and portland cement, containing 50% recycled material.
Concrete's environmentally friendly features make it the building material of choice for sustainability....meeting present needs without compromising the ability of future generations to meet their own needs.
Green mix concrete is environmentally friendly or recyclable concrete. The main idea of green mix concrete comes from the anti-environmental production methods used to produce the main ingredients of concrete.
Concrete is a compound material or mixture. It consists of cement, aggregates or chips and water.
- Cement production involves: Calcium Oxide, burning of Coal that produce a lot of Co2, CO, SO2, and generation of heat.
- Aggregates production involves: Mostly bricks and burning coal or tree, Stone that produce huge amount of heat, Co2 and destroy the forest.
- Concrete produce heat during the hydration reaction.
- Concrete production need fresh or clean water that is not even available for drinking in many places in the world, let alone for making concrete!
As concrete is one of the primary building materials and millions of tons of concrete is used for building various kinds of structures all over the word each year, Scientists are constantly searching for better and environmentally friendly ways for producing concrete considering the above matters. Green mix concrete is one of the primary outcomes of such research that targeting the mix design of concrete to produce less heat during its hydration reaction and using through-away materials (plastic chips that are not bio degradable) in certain percentage as aggregate.
Green Concrete is a sustainable concrete product that use to develop sustainable structures which has minimum impact on environment (without compromising future generation) considering followings:
1. Minimizing Environmental effects.
2. Environmental Friendly Concrete (Optimized mix by using supplementary cementatious material and especial additives)
3. Minimizing Co2 emission to the environment.
4. Optimization of energy performance.
5. cost / competitiveness of cost effective.
6. And right way to use technology.
