Ferrocement′s attribute as a thin reinforced concrete and laminated cement based composite enables numerous applications where strong and tough protective shell is needed. It is used in the construction of cylindrical and spherical shells as liquid retaining structures. The stress condition at a point in such shell structures is biaxial state of tension-tension. A study on the behaviour of ferrocement in biaxial state is important for establishing a rational design. The authors carried out a full-fledged investigation on ferrocement under different biaxial stress conditions. The present investigation deals with the study of ferrocement in biaxial tension-tension based on hollow cylindrical specimens. An interaction curve is proposed to estimate the strength of ferrocement in biaxial tension-tension. The relationship between octahedral normal and shear stress is also presented.
