Abstract : This report is a continuation of the former efforts to elucidate the behavior of ferrocement concrete in static and dynamic stress fields. The influence of various reinforcements on pre and post cracking of thin sections forms the main topic of this report. The objects of the testing program were to compare the effectiveness of various steel mesh configurations in arresting crack propagation in stressed members; to provide experimental data for checking theoretical predictions of strength based on material parameters; to identify areas of future research potential. The work to date has been devoted to flexural and direct tensile tests on thin slabs. The slabs were reinforced uniformly with steel meshes of various patterns. The matrix consisted of microconcretes, and some variations in the mix design were incorporated.
