Understanding the Process of Internally Cured Concrete using Prewetted Aggregate
Internally cured concrete leverages a specialized process whereby aggregate is pre-wetted before inclusion in the concrete mixture. This procedure results in the formation of an independent curing environment within the structure. The pre-wetted aggregate traps moisture, providing a sustained source of hydration for cement paste over an extended period. This extended curing phase strengthens the development of higher compressive strength concrete structure.
The science behind internally cured concrete with prewetted aggregate lies in the interplay of diverse factors, comprising the type and amount of pre-wetting agent, the porosity of the aggregate, and the properties of the cement used.
