Ferrocrete: Properties, Advantages & Disadvantages

Ferrocrete is derived from the words i.e. ferrous and concrete, ferrous means anything made from iron and concrete, which is made from cement, fine aggregate (i.s. sand), coarse aggregate (i.s. trap metal or broken pieces of stones), and water. It is applied over an "armature" of metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebars.

Concrete Thinking (ASU Research Magazine)

Concrete is a composite material made of multiple other materials. Mobasher''s idea is to make concrete even better by reinforcing it with fabric. Cement is a powder of limestone and clay. Concrete is a mixture of cement and sand, gravel, pebbles, broken stone or slag. Adding fabric to concrete strengthens it and makes it energy absorbent.

Reinforced Cement Concrete: Types, Advantages & Disadvantages

 · Disadvantages of reinforced cement concrete: The tensile strength of this concrete is 1/10 of its compressive strength. The price of this concrete used for casting is comparatively excessive. The RCC column section is larger than the metal section for multi-story construction. Due to the shrinkage, the crack increases and the strength decreases.
