DESCRIPTION
Green Buildings-Reinforced Masonry Construction Method Sir, I would like to introduce one such building construction system which may change the total scenario of construction business in near future. This building system can put a great role in making Green Buildings, Eco-friendly homes, Hotel, Slum Re-development, Transit Camp. It’s called Reinforced Masonry or C.M.U.,or Reinforced Concrete Block Masonry.(R.C.B.) Hope you must have heard about this or else to know more please visit our web site. www.AffordableConstruction.in 1)R. C.C.type of construction was taught by British & we are following Beam & Column type of construction for the last hundred years or so in India. 2) R. C. C. building needs repairs within 15 years of construction. Not that anything is wrong with R. C. C. but there is more scope to use inferior material & workmanship in R.C.C.& hence need for early repair. 3)Our Forts, Old buildings V. T. Station. Municipal Bldg., Palaces, Towers are generally constructed by Stone Masonry load bearing method & have stood for hundreds of years without any major repair work. 4)The same load bearing technology has been further developed in U.S.A.& is called R.C.B. which is Speedy, Sturdy, Simple, Durable, Eco-Friendly also saves 20%in construction cost. Called R.C.B./Reinforced Masonry. 5)R. C.B. is a proven method of construction with millions of buildings being built by this way in the world. 6) 300 buildings are built by R. C.B.design in India & U.S.A. by us. 7)Eco-friendly as it SAVES 100%bricks,50%steel+shuttering,40%concrete,25%utility bill. So R.C.B./C.M.U./Reinforced Masonry is Eco-friendly, Affordable,Durable,Speedy,Simple. ------------------------------------------------------------------------------ Advantages of shear wall R.C.B. method of construction ------------------------------------------------------------------------------- A)Economy : As steel, cement,shuttering, concrete & Labour required is almost half & due to simplicity of construction & speed minimum saving is Rs. 200/- per sq. ft. B)Fire Proof : Due to concrete block & 3" cover to steel, rusting is minimized & such buildings are fire & bomb last proof. C)Durable : Concrete blocks are attractive, durable and have excellent thermal, acoustic properties. No repair like R.C.C. is needed in every ten years. D)Earthquake: Load bearing concrete blocks can be designed to be wind, earthquake resistant too. E)Speed: No heavy equipment needed on site, less form-work, less steel so construction is simple, speedier & hence economical. E)Architecture: Ancient type of architectural elevation is also possible by R.C.B type of construction. --------------------------- RCB Users --------------------------- BMC Bhojwani const.
