Nano Technology For Concrete :

Nano Concrete Technology and its benefits
Nano Concrete Technology
The most active topic nowadays for research in Nanotechnology and has many promises and wide applications in almost all fields and Civil Engineering is no other field which has also seen the advantages of this technology. Also Concrete is the most usable material in the construction industry and it's been required to improve its quality. The research and development in this field have shown significant improvement than conventional concrete. 

Why Nanotechnology For Concrete?

This technology improves the material's bulk properties and control or manipulates materials at the atomic scale. 
It helps to obtain a thin final product and has a faster setting time so the formwork can be removed faster and cost can be saved in formwork and becomes cost-effective.

How Is Nano Concrete Achieved :

The material used in conventional concrete is approximately greater than 100 nanometers. So the use of substances where at least one dimension is less than approximately 100 nanometers. Nanomaterial which is used in concrete are 
  • Carbon Nanotubes
  • Nano Silica
  • Polycarboxylates
Carbon Nanotubes help in achieve high flexibility and stiffest and strongest fibers. Also, carbon nanotubes are more effective than carbon fibers.
Nano Silica improves workability with reduced water/cement ratio, the use of plasticizing additives is unnecessary. Also helps in filling micro and nanopores. 
Polycarboxylates help to reduce the range of water and this helps in Underwater Antiwashout Concrete.

Advantages Of Nano Concrete :

  • Lowers Cost per Building Site
  • Concrete with less final setting time
  • Improves Workability
  • Reduces The Use Of Plasticizers

Disadvantages Of Nano Concrete :

  • There are fewer Nanomaterial sources
  • There are not many Machines to produce Nanomaterials

Projects Where Use Of Nano Concrete Technology Is Done :

  • The Gartnerplatzbrucke, across Kassel River in Germany
  • The Jubilee Church, Rome.

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
