Measure of maturity of the concrete structure
Abstract
n this paper we determine the degree of maturity in situ concrete structure. To do this, temperatures are measured in the concrete foundations of a structure, from the first hours of hydration, to 28 days, with a device developed at the Faculty. Simultaneously testing compressive strength are performed establishing the relationship with temperature, with expressions Nurse-Saul and Arrhenius. The results allowed to determine the maturity curve of the studied concrete and establish the degree of maturity in each of the different parts of the structure. The use of this methodology allows to control the entire concrete received, its homogeneity and to monitor resistance in real time.
Keywords: maturity; concrete; temperature; resistance.
