Sky Bridge | Langkawi, Malaysia | Discoveries | Engineer Ji

Design & Construction:



  • The bridge is 125 meters long, and 1.8 meters wide (the middle section has a wider walkway), with two steel railings as well as steel wire mesh on either sides. It is designed as a curved walkway to maximise the viewing experience, providing shifting perspective as a visitor walks along the bridge. The walkway, formed of steel and concrete panels set on top of an inverted triangular truss, connects two hilltops at Gunung Mat Chinchang. The first 25m of the bridge is straight, following 3 curved 25m sections, then a final straight 25m section.

Plastic Roads | Plastic Pavement Pros & Cons | Buzz Mate | Engineer Ji


Plastic Roads | INDIA


  • Plastic roads are roads made either entirely of plastic or of composites of plastic with other materials. 
  • Plastic roads are different from standard roads in the respect that standard roads are made from asphalt concrete, which consists of mineral aggregates and asphalt

Introduction to Rails | Railway Engineering | Part I

Rails:     


  • The rails on the track can be considered as steel girders for the purpose of carrying axle load.
  • Rails transfer Axle load to the sub-grade through sleepers and ballast.
  • Rails convert the moving wheel load of train into point load which acts on the sleepers.
  • Rails are made up of high carbon steel, to resist wear and tear.
  • On points and crossing rails of medium carbon and high manganese steel is used.
  • In India rails are

Chemical Composition of Raw Materials | Construction Materials | Cement | Part II

Chemical Composition of Raw Materials | CEMENT

CEMENT | Civil Engineering | Engineer Ji | Er. Neeraj Gosain

  • The three basic constituents of hydraulic cements are Lime, Silica-alumina and Iron-oxide.
  • The relative proportions of these oxide compositions are responsible for influencing the various properties of cement.
  • An increase in lime content beyond a certain value makes it difficult to combine completely with other compounds.
  • Consequently, free lime will exist in the clinker and will result in the unsound cement. An increase in silica content at the expense of alumina and ferric -oxide makes the cement difficult to fuse and form clinker.
  • The approximate limits of chemical composition in cement are given in table.
