GREEN CONCRETE

                                                                  

Green Concrete

Green concrete is environementel friendly concrete. Concrete that use less energy in its production and produces less carbon dioxide than normal concrete is green concrete . 

Most of carbon dioxide in concrete form the cement manufacturing process . A typical cubic metre of concrete contains about 10% cement by weight . Use of Virgin aggregate contributes about 1% of all carbon dioxide emissions from a typical cubic of concrete . Therefore , the use of alternate aggregate is desirable . The use of local & recycled aggregate is desirable as it can reduce transportation and fuel cost  & support sustainable development

Material for Green concrete

 

Green Construction Material are composed of renewable , rather than non renewable resources . Green material are environmentally responsible because impacts are considered over the life of the product

        Depending upon project-specific goals , green material may involve an evaluation of one or more of the following criteria.

1.  Locally available

2. Salvaged , re furnished , or re-manufactured 

3. Reusable or recyclable   

Advantages of Green Concrete

1. optimized mix design mean easier                   handling , better consistency & easier              finishing

2. Reduction in shrinkage & creep 

3. Green concrete uses local & recycled materials in concrete

4. The heat of hydration of green concrete is significantly lower than traditional concrete

5. This result in a lower temperature rise in large concrete pours which is distinct advantage for green concrete
