Delving into the Mechanics of Internally Cured Concrete with 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 enclosed curing environment within the concrete mass. The pre-wetted aggregate holds moisture, offering a sustained source of hydration for the cement over an extended period. This prolonged curing phase strengthens the development of a more robust concrete structure.
The science behind internally cured concrete with prewetted aggregate is based on the interplay of multiple factors, comprising the type and amount of moisture retention agents, the porosity of the aggregate, and the attributes of the cement used.
