Delving into the Mechanics of Internally Cured Concrete with Prewetted Aggregate
Internally cured concrete leverages a innovative process in which aggregate is pre-wetted before inclusion in the concrete mixture. This procedure results in the formation of a self-contained curing environment within the structure. The pre-wetted aggregate holds moisture, providing a sustained source of hydration for cementitious material over an extended period. This prolonged curing phase strengthens 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, including the type and amount of additives, the porosity of the aggregate, and the attributes of the cement used.
