Presents comprehensive test data on the tensile behavior of 12.5 cm thick ferrocement plates. The main variables investigated were mesh geometry, specific surface, volume fraction, mesh yield strength and skeletal bars. The specimens were specially designed to insure failure in the gage length. The matrix was proportioned for high strength, high workability, and high durability with low water-to-binder ratio, and 50 percent fly ash replacement. Cracking and deformation were monitored throughout the loading range. The results showed that the composite properties of elastic modulus and ultimate tensile strength could be satisfactorily predicted. However, the cracking behavior for a wide range of mesh geometry could not be satisfactorily predicted by a single unique relationship. There was, however, good correlation between the composite properties of ultimate tensile strength and ultimate flexural strength. The results show that by suitable design of the matrix and the reinforcement, high-strength, ferrocement sheets with high crack resistance can be developed for a variety of structural applications.
