Abstract:
Presents an adaptation of a previous model (the generalized Feret's law with account for the Maximum Paste Thickness) for structural fly ash concrete. A kinetics term is introduced to predict the compressive strength development between seven and 365 days. On a set of data taken from the literature, the mean accuracy of the model is equal to 2.1 MPa. Moreover, the formula only incorporates a limited number of parameters, which can easily be determined from standard mortar or concrete tests. Therefore, the model appears to be suitable for a computer-aided concrete proportioning software.
