Abstract:Purpose was to examine, under uniaxial compression, the monotonic and hysteretic stress-strain properties of normal and lightweight concrete with the addition of silica fume, and to propose a mathematical model of stress-strain curves based on experimental data. The mathematical model has been developed to predict the complete stress-strain curve of concrete in compression, in terms of the addition of silica fume to cement. The parameters of the model have been adjusted using system identification techniques to obtain the best match possible between the experimental data and the model predictions. The experimental data were obtained by testing normal and lightweight concrete cylinders; the amount of the addition of silica fume was varied, respectively, from 0 to 28 and from 0 to 24 percent by weight of cement.
