Curing (concrete)

Curing is the care concrete gets after it's placed and finished — holding moisture in and temperature steady so the cement can keep hydrating and building strength. Concrete doesn't just dry; it reacts, and that reaction needs water and time. Cut the curing short and the surface loses moisture too fast, so the concrete ends up weaker, dustier and more prone to cracking than the mix on paper. Curing is a step, not an afterthought — wet burlap, curing compound, plastic or ponding, kept up for a set period.

Why it matters

The strength on the mix design assumes the concrete was cured; skip it and the slab or wall never reaches that number, no matter what the ticket said. Poor curing shows up later as crazing, scaling and low surface strength that a coating or topping won't fix.

What an inspector looks at

The check is that a curing method actually went on and stayed on for the required time — compound applied evenly, cover kept wet, edges not left to dry out — and that hot or cold weather got the extra protection it needs. It's verified in the days after the pour, not just at placement.

RTI is photo-gated, so curing is documented as it happens — the wet cover, compound or protection shown on the concrete with a timestamp, the proof that the slab was cured and not just poured and walked away from.

Standards it's verified against

Knowing the term is step one. Proving it is the job.

RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
