At the same time ferrocement is better earthquake resistant and wind resistant and resistant to all disasters. Ferrocement requires much less quantity of cement and steel giving better performance thus environment friendly.

Is ferrocement stronger than concrete? In the technical sense the important difference is that the specific surface of reinforcement is much higher in ferro-cement than in conventional reinforced concrete. This results in very high tensile strengths for ferro-cement, under favorable conditions almost equal to compressive strengths.
