  98. 98. Advantages of R.C.B. Method.  Economy : As steel, cement, formwork, concrete & Labor required is almost half & due to simplicity of construction & speed, minimum saving is Rs. 300/- per sq. ft. Also by optimum planning for R.C.B. get up to 10% more carpet Area.  Speed: No heavy equipment needed on site, less formwork, less steel so construction is simple, speedier & hence economical.  Fire Resistant : Due to concrete block & 3.5" cover to steel, rusting is minimized & such buildings are fire resistant too.
  99. 99. Durable: Concrete blocks are attractive, durable and have excellent thermal, acoustic properties. No repair like R.C.C. is needed in every fifteen years.  Earthquake: Load bearing concrete blocks can be designed to be wind, earthquake resistant too. Up to 22 Storied.  Warranty: R.C.B. Method assured warrantee against heavy rain, flood, fire, storm, earth quake & all other natural calamities for at least 50 years.  Architecture: Ancient type of architectural elevation is also possible by R.C.B type of construction. Also R.C.B. is Environmental friendly too.
  100. 100. R.C.B. is also Useful For 1) Retaining Wall 2) Bridge Abutment 3) Bridge Pier 4) Highway Culverts
  101. 101. REMARKS 1) ForAffordabilityArchitects/Engineers/Clients need to take a lot of efforts in Planning, Design, Detailing & technology. 2) Client must learn to pay for the Planning, Design and Technology in advance. 3) Affordable structure is always green. 4)Affordable does not mean cheap construction. 5) By Optimum Planning we get 10% more CarpetArea.(Bonus to the Builders)
  102. 102. CONCLUSIONConsidering Durability, Speed, Simplicity, 30% Saving & 10% more Carpet Area. This Eco Friendly R.C.B. Construction is Particularly Suited For, Housing, Slum Project, Transit Camp, Schools & Hospital, Hotel & Bungalow, Industrial Projects, Retaining Wall, Culverts etc.
