CREEP AND FATIGUE CHARACTERISTICS OF FERROCEMENT SLABS.

The paper presents the study of flexural creep characteristics of ferrocement which was taken up with particular reference to twenty rectangular slabs (300 mm multiplied by 600 mm) subjected to sustained central line load for a period up to ninety days. Based on the observations, the time-deflection curves were plotted and a model to estimate the time dependent flexural deflection is suggested. The tests for fatigue life and fatigue creep of ferrocement slabs were carried out on thirty-six similar slabs as for the creep and central line loading only. The effect of repeated loads on the flexural rigidities of slabs has been discussed and the load deflection hysteresis loops have been plotted.
