Understanding the Process of Internally Cured Concrete using Prewetted Aggregate
Internally cured concrete leverages a unique process that aggregate is pre-wetted before mixing with the concrete mixture. This method results in the formation of an independent curing environment within the concrete mass. The pre-wetted aggregate traps moisture, providing a sustained source of hydration for cementitious material 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 revolves around 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.
