Abstract


This study attempts to show the differences found between average resistance, after 28 days, obtained in the laboratory and that predicted when the C/A relationship has been calculated using the general De la Peña formula. This difference is considered to be sufficient to justify modifying the content of the formula, though not that of its structure. It is suggested that the difference may be due to the use of PA cement, when the formula originates from the tests with pure Portland cement. If this is the case, it would simply be a question of generalizing the formula to another type of cement.
