Reinforcement Checks

Reinforcement Cover:
It is essential that the steel reinforcement bars are surrounded sufficient impermeableconcrete to protect them from corrosion, and to allow the combined strength of the reinforcement and concrete to be effective.

Pre-Concrete Checks for Reinforcement:
The pre-concrete check for reinforcement essentially comes in two parts. The first part is a visual inspection by the clerk of works or equivalent.

COAGULATION - Definition and Measurement of Colloids

Many of the contaminants in water and wastewater contain matter in the colloidal form. These colloids result in a stable “suspension”. In general the suspension is stable enough so that gravity forces will not cause precipitation of these colloidal particles. So they need special treatment to remove them from the aqueous phase. This destabilization of colloids is called “coagulation”.
