19 CURING OF CONCRETE • The process of keeping concrete wet to enable it to attain full strength is known as curing • The objective of curing is to prevent loss of moisture from concrete due to evaporation or because of any other reasons • Curing should be done for a period of three weeks but not less then 10 days

Air voids reduce the strength of the concrete For every 1% of entrapped air the strength falls by somewhere between 5 and 7% This means that concrete containing a mere 5% air voids due to incomplete compaction can lose as much as one third of its strength Air voids increase concrete s permeability That in turn reduces its durability
