Ferrocement is a highly versatile form of reinforced concrete made of wire mesh, sand, water, and cement, which possesses unique qualities of strength and serviceability. It can be constructed with a minimum of skilled labour and utilizes readily available materials.
Ferrocement has a very high tensile strength-toweight ratio and superior cracking behavior in comparison to conventional reinforced concrete. This means that thin ferrocement structures can be made relatively light and watertight. Hence, ferrocement is an attractive material for the construction of prefabricated housing units, boats, barges, and other portable structures.Figure 1. show all the component of ferrocement wall.
Admixture: Chemical admixtures used in ferrocement serve one of the following four purposes: water reduction, which increases strength and reduces permeability; air entrainment, which increases resistance to freezing and thawing; and suppression of reaction between galvanized reinforcement and cement.
 Mortar Mix:The reaction of port land cement and water results in formation of hardened cement paste. The ranges of mix proportions recommended for common ferrocement applications are sand-cement ratio by weight, 1.5 to 2.5, and water-cement ratio by weight, 0.35 to 0.5. Fineness modulus of sand, water-cement ratio and sand-cement ratio should be determined from trial batches to insure amix that can infiltrate (encapsulate) the mesh and develop a strong and dense matrix. Water reducing admixtures may be used to enhance mix plasticity and retard initial set, as with conventional concretes. The behaviour of mortar is similar to that of plain concrete. The major distinction is the size of the aggregate used. In general a good quality mortar is stronger and more durable than good quality concrete; however, their basic response to the environment is essentially the same. 
Ferrocement products are an ideal substitute for wood and they can be extensively used in various components of a housing like door, Roofing etc.Indian Experiences have shown that construction cost could be reduced by about 20to 40% if ferrocement products are used in place of conventional wood or R.C.C.Components. Developing countries where mass social housing projects are being taken up the use of ferrocement components would go a long way in helping them to build houses at economical cost and also at a faster rate.

Factors Affecting Selection of Foundation for Buildings?

Image
Factors which affect selection of foundation for a building can be many from the soil conditions to the type of structure and loads from the building. All the factors are considered during selection of foundation for durable building construction. Factors Affecting Selection of Foundation Following are the factors which affect the selection of suitable foundations for building construction: Loads from building Type of soil Type of structures in neighborhood Type of foundations 1. Loads from Building The first factor considered is loads from building on the foundation. This load is a combination of dead load and imposed loads on the buildings. Other loads such as wind loads, earthquake loads, snow loads etc. are also considered based on location. The quantity of loads depends on the type of structure, number of floors and material of construction. As the number of floors increases, the dead load and imposed loads also increase. Choice of material for construction su...

HOW TO DETERMINE DEPTH OF FOUNDATION

Image
Many factors affects the determination of depth of foundation. Calculation for foundation depth is done based on type of soil, ground water table, loads from structure, bearing capacity of soil and other factors. General factors to be considered for determining depth of foundation are: 1. Load applied from structure to the foundation 2. Bearing capacity of soil 3. Depth of water level below the ground surface 4. Types of soil and depth of layers in case of layered soil 5. Depth of adjacent foundation The minimum depth of foundation should be considered to ensure that the soil is having the required safe bearing capacity as assumed in the design. However, it is advised to carry out soil investigation before deciding on depth of foundation. Soil investigation report will suggest the foundation depth based on the type of structure, soil properties, depth of water table, and all other variable that should be considered. Soil investigation report provides bearing capacity of ...

WHAT IS VOLUME BATCHING OF CONCRETE AND HOW IT IS DONE IN FIELD?

Image
WHAT IS VOLUME BATCHING OF CONCRETE? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it  Volume Batching . Below are mentioned some of important points to remember before adopting volume batching method in field. Volume batching is not a good method for measuring concrete materials. It is not applicable in case of reinforced concrete structure. This method of concrete batching may not be economical. It can be only used for unimportant concrete or for small concrete works. HOW VOLUME BATCHING IS DONE IN FIELD? Before batching concrete ingredients in terms of volume, we need to know two things. What is the relative proportion of concrete ingredients in terms of volume? What is the water-cement ratio? After knowing these two things you can proceed to batch concrete ingredients in field. The table shown below ca...
