What is ferrocement ? List the properties of ferrocement.
Ferrocement is a comparatively new material. It consists wire meshes and cement mortar. It consists of closely spaced wire meshes also which are impregnated with rich cement mortar mix. The wire mesh is usually of 0.5 to 1 mm dia wire at 5 mm to 10 mm spacing and cement mortar is of cement sand ratio of 1 2 or 1 3 with water/cement ratio of 0.4 to 0.45. These elements are usually of the order of 2 or 3m in thickness with 2 to 3 mm external cover to the reinforcement.
Behind this material the basic ‘idea is that concrete can undergo large strains in the neighbourhood of the reinforcement and magnitude of strains depends on the distribution and subdivision of reinforcement throughout of the mass of concrete.
Advantages
(1) Less crack width
(2) Simplicity in construction
(3) Easier moundability
(4) Lesser dead weight
(5) Non-correcsive nature
(6) High tensile, strength
(7) Easy repairability
