In laboratory, the curing of test specimens is carried out prior to the testing of specimens at 7th day and 28h day. Briefly explain the importance of this procedure. Discuss the possible ceffecet on concrete if no curing is provided. 1.

Solution

Curing is the maintaining of an adequate moisture content and temperature in concrete at early ages so that it can develop properties the mixture was designed to achieve. Curing begins immediately after placement and finishing so that the concrete may develop the desired strength and durability.

If not cured, the concrete would not develop the strength required because of incomplete/partial hydration reaction.
