Delving into the Mechanics of Internally Cured Concrete with Prewetted Aggregate
Internally cured ACI 104-71 (1997) – Preparation of Notation for Concrete concrete employs a innovative process whereby aggregate is pre-wetted before inclusion in the concrete mixture. This technique results in the formation of a self-contained curing environment within the structure. The pre-wetted aggregate retains moisture, offering a sustained source of hydration for the cement over an extended period. This prolonged curing phase contributes to the development of higher compressive strength 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 properties of the cement used.
