Abstract


This study presents the results of a series of concrete test pieces of three different mixtures: I/45A cement; Portland cement with additions; Portland with fly ash. All were subjected to six different types of curing, with the aim of studying the evolution of their compressive strengths in terms of the grade of "maturity" reached at early ages.
The study makes some practical recomendations on the interrelationship between curing processes and compressive strength and is included in the context of the research program on "Tecnologies for Housing of Social Interest".

Keywords
