In this article on the basis of analysis of the influence of different technological-environmental parameters, such as the type of cement, water/cement ratio, initial curing temperature, time of conservation work, content of cement, additions, additives and consistency in the evolution of the concrete compressive strength, obtained a calculation equations and some graphs to estimate the resistance evolution of the concrete HA-25/B/20/IIa and HA-30/B/20/ IIa from 3 to 28 days for each initial temperature curing interval specified and for the sample of concrete. So are based on 67782 data of different compressive strength of prepared concrete in the province of Valencia during the years 1996 to 2011, that has allowed to compare the equations obtained from regression with a significant database.
