Cement Content - GBG

The cement content of concrete is important from the aspect of durability, impermeability and strength. Too low a cement content may cause inadequate structural capability or more frequently may not provide a durable protective environment for the steel reinforcement, permitting rapid carbonation and subsequent loss of the protective alkaline environment for the steel. Too high a cement content may …
