Abstract:A theoretical model is presented to predict the width and spacing of cracks in ferrocement elements in tension. A parametric study was also conducted to study the influence of parameters such as bond stress, volume of reinforcement, size of reinforcement, properties of mortar and reinforcement on the width and spacing of cracks. The theoretical results indicate that the spacing and width of cracks are significantly affected by bond stress, diameter and volume of reinforcement. An experimental investigation was conducted on ferrocement specimens in tension with varying steel content and the results obtained are shown to be in agreement with theoretically predicted values. Practical guidelines are suggested for the control of tensile cracks in ferrocement elements.
