Understanding the Process of Internally Cured Concrete using Prewetted Aggregate
Internally cured concrete utilizes a unique process in which 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, delivering a sustained source of hydration for the cement over an extended period. This extended curing phase strengthens the development of higher compressive strength concrete structure.
The science behind internally ACI 336.1-01: Specification for the Construction of Drilled Piers cured concrete with prewetted aggregate revolves around the interplay of diverse factors, such as the type and amount of additives, the porosity of the aggregate, and the characteristics of the cement used.
