Formwork and its types and uses
Formwork

The fresh concrete after mixing the ingredients will which is poured into the required molds in its plastic stage to attain its full strength. The molds are called Formwork. 
Types :

The types of formwork which are used are classified as :

  1. Based on Material
  2. Based on Use

Based on Material :

1. Timber Formwork :

Timber Formwork and its details
Timber Formwork

The formwork are usually made of wood and called timber formwork. They are easy to use and assemble and remove after concrete has achieve its required strength. 
Easy availability, good strength, and flexibility are key significance of timber formwork.

The modern form of this formwork is Plywood Formwork.

2. Plastic Formwork :

Plastic Formwork

This formwork is used where it is required again and again such as apartment buildings or high rise buildings where each floors are require to have same formwork. 
This formwork is easy to assemble and remove same as the timber formwork but the flexibility of the formwork is is limited as the shape and size will not be able to change as same as timber formwork.

 3. Steel Formwork :

Steel Formwork

This formwork is made of steel and is fixed with nut bolts. The steel formwork is see to be used in small bungalow and villa construction and have same function as plastic formwork. 
Easy to assemble and remove with very few labor work required and have long lifetime.

Based on Use :

  1. Formwork for Floor
  2. Formwork for Columns
  3. Formwork for Slab
  4. Formwork for Wall
  5. Formwork for Staircase
This are made from the above discussed formwork of different material.
Recently with use of technology and new techniques the formwork's are made of and made patient made and are made available in market for different use.
Slip Formwork and its details
Slip Formwork

For construction of chimneys and steam towers in the nuclear power plants where Slip formwork are used. This make the construction work double the speed compared to conventional formwork.

Great Man-Made River (GMR)

Libya's Great Man Made River: The Great Man-Made River in Libya is one of the most ambitious Civil Engineering Project in history of mankind.  In the year 1953, the Libya Government found out not only vast oil reserves but also vast quantity of fresh water locked under the strata, most of the water was trapped around 7000-30000 years ago which is divided in 4 different basins. The first basin is named Kufra basin which is neat Egypt Border which covers almost 35000 sq kilometer which is quite deep around 2000 m deep. The other basin is in Sirte Basin which cover 10000 sq kilometer, third in Murzuk Basin and the last in Jabal Fezzan Basin covering 4800 sq kilometers area.  The GMR project will be used to transfer water to North of the country to provide water for irrigation purpose for more than 6 million  people. This will be a changing point  for Libya and the Colonel Muammar Gaddafi called it the Eighth Wonder of World. The work started in 1984 of the project and estimated to be

DDSS - Roof Truss

Design Of Roof Truss: If load from purlin, false ceiling etc are applied in between the nodes, then principal rafters or main ties are designed for combined stresses from bending and axial loads. IS 800 - 2007 provides general design procedure for the angle Purlins conforming to steel grade of Fe 410 of O, S, W  and not exceeding slope more than 30 degree based on live load of 750 N/m2. Loads on Trusses: Dead Load, Live Load, Wind Load and Snow Load are types of loads on the truss. The main in Design of Truss in small truss and some Industrial Truss. Dead Load (DL): If spacing of Truss is 4 m and pitch of truss is 1:4 then self weight of the truss is taken as, w = (l/3+6) of plan area .... in kN/m2. Then add all the dead loads with this such as GI sheet, AC sheet and Purlins weight. Then multiply with the plan area to get the actual DL. Live Load(LL): If the angle is less than 10 degree, then the LL will be directly taken as 750 N/m2. If slope of truss is more than 10 degree, live load

Timber Buildings !?

 Why do we need a timber building? Yes, timber buildings. As on earth human population is on an exponential rise, many and many people are trying to get home in a city where they have easy excess for the workplace for their own living. In the near future, as the population gets more concentrated in cities more and more structures I mean Tall Structures need to be built. Loading Bearing and Comparison So now architects and builders have opted for the old Technic of using timber as a building material eliminating concrete and steel. Yes, it is very hard to find this amount of trees but not impossible. It can be grown and regrown as needed. Many projects have been in progress of this idea and it reduces about 75% of carbon emission as compared to concrete and steel structure. Using timber coming directly from the forest doesn't have the appropriate strength required for a high-rise building. So designers came up with the new idea of CLT i.e. Cross Laminate Tim
