What is ferro cement PPT?

TYPICAL CROSS SECTION OF FERROCEMENT. TECHNIQUES OF MANUFACTURES  Hand plastering  semi-mechanised process  Centrifuging and Guniting MATERIALS USED IN FERRO CEMENT  Cement mortar mix  Skeleton steel  Steel mesh reinforcement or Fibre-reinforced polymeric meshes.

What is ferro cement in concrete technology?

Ferrocement can be considered as a type of thin walled reinforced concrete construction in which small-diameter wire meshes are used uniformly throughout the cross section instead of discretely placed reinforcing bars and in which Portland cement mortar is used instead of concrete.

What is the ratio of cement in ferro cement?

The metal commonly used is iron or some type of steel, and the mesh is made with wire with a diameter between 0.5 mm and 1 mm. The cement is typically a very rich mix of sand and cement in a 3:1 ratio; when used for making boards, no gravel is used, so that the material is not concrete.

Why ferro cement is used?

Uses of Ferrocement It saves cement and steel in the construction of structures, so it is used in residential buildings. Ferrocement is utilized for making overhead water tanks for domestic purposes. The tank is lightweight and can be transported easily.

What is ferrocement slab?

Ferrocement slab panels (FSPs) are thin-walled elements constructed from cement, sand, water and various types of mesh [1], [2], [3]. Their appropriate strength, hardness, durability and lightness made them distinguished from other thin construction materials [3], [4], [5], [6].

What are the properties of ferrocement?

Properties of Ferrocement

  • Ferrocement members are durable and versatile material.
  • Ferrocement has low w/c ratio and produces impermeable structures.
  • It has less shrinkage and weight.
  • Ferrocement structures have high tensile strength, stiffness and rigidity.
  • They have a better impact and punching shear resistance.

What are the materials used in ferrocement structures?

What is the minimum slab thickness possible in ferrocement construction?

Ferrocement is a thin construction element with thickness in the order of 10-25 mm (3/8–1 in.)

Which are the properties of ferrocement?

What are the properties of ferro cement?

What is the difference between ferro-cement and 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.
