Delving into the Mechanics of Internally Cured Concrete with Prewetted Aggregate
Internally cured concrete leverages a specialized process that aggregate is pre-wetted before inclusion in the concrete mixture. This procedure results in the formation of an independent curing environment within the matrix. The pre-wetted aggregate holds moisture, delivering a sustained source of hydration for cement paste over an extended period. This lengthened curing phase enhances the development of higher compressive strength concrete structure.
The science behind internally cured concrete with prewetted aggregate is based on the interplay of various factors, comprising the type and amount of moisture retention agents, the porosity of the aggregate, and the properties of the cement used.
