Abstract

The curing process is one of the most important steps in the concrete execution, providing the complete hydration of the Portland cement compounds, avoiding the shrinkage phenomenon and ensuring the strength of the structure. This paper intends to understand the influence of immersed in water and lime curing, chemical curing, with the use of plastic film, and open air curing on concretes with axial compressive strength fck 30 Mpa. The specimens were analyzed for 63 days, at 4 ages of rupture. The concretes, when submitted to immersed curing in water and lime, had a significant difference when compared to the other methods. The concretes that were submitted to the other cures had a lower mechanical resistance, sometimes significative, sometimes not significant when compared among themselves.
