The scope of +his investigation was to better understand ferrocement as an engineering material and to predict its design properties. In spite of growing popularity of this material basic design information is scant. The influence of types, sizes, and volumes of wire meshes on elastic, cracking, and ultimate behavior of ferrocement in uniaxial tension was studied. If was observed +hat the ultimate strength of ferrocement is the same as that .of mesh alone while its modulus of elasticity can be predicted from those of mortar and mesh. The specific surface of the reinforcement strongly influenced the cracking behavior of ferrocement. An analytic relation between crack spacing and +he specific surface of the reinforcement was developed. The relatively large specific surface for ferrocement may account for the combination of very small width of cracks and high tensile strength.
