Green Concrete and its Scope in India
Recycling industries in many parts of the world convert low-value waste into secondary construction material such as aggregate grades, road materials and aggregate fines. Green Concrete may be used in concrete for bulk fills, bank protection, base/fill of drainage structures, pavements, sidewalks, kerbstones and

A method of forming a cement composition. The method comprises adding to a hydraulic cementitious material a first strength-enhancing agent and a second strength-enhancing agent, wherein the content of total alkali (Na20 equivalent) in the hydraulic cementitious material is less than or equal to 0.7% by weight of the cementitious material.

CHAPTER 5 Environmental deterioration of concrete
The total porosity of concrete is highly dependent upon the original amount of water used in its production. This is usually expressed in the form of water-to-cement ratio, w/c (or w/cm), the amount of water per unit weight of cement. The typical range of w/c used is
