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.

Timber Buildings !?

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 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 Timber which …
