1) The document discusses reinforced concrete block (RCB) construction as an affordable and sustainable building method. 2) RCB uses hollow concrete blocks with steel reinforcement that allows 20% savings in construction costs compared to RCC. It is a proven American technology used worldwide for over 90 years. 3) RCB construction is described as economical, speedy, simple, durable, earthquake resistant, and suitable for housing, schools, hotels, and other projects. Over 300 buildings in India have used this method.

2. Innovation In Construction Technology For Affordable Housing

3. While Designing The Building it is More Appropriate To Work Out Which isThe Most Suitable Construction Method i.e., R.C.C., STEEL, PRECAST, BRICK / R.C.B.

4. Construction Method MUST Be Attractive Economical Eco Friendly Proven Simple Speedy Sturdy Sustainable

5. 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.

6. 3) Our Forts, Old buildings, V. T. Station, Municipal Bldg., Palaces, Towers are generally constructed by Stone Masonry load bearing method & have stood since hundreds of years without any major repair work. 4) The same load bearing technology has been further developed in U.S.A. which is Speedy, Sturdy, Simple, Durable, Eco-Friendly which also saves 20% in construction cost & is called R.C.B./ Reinforced Masonry/ C.M.U.

7. As Air is freely available and Hollow Concrete Block is 50% hollow, if a structure is built by R.C.B. the cost of construction is slashed down.

74. Economy (Save up to Rs. 200 / SF of slab area) Need to optimize your approved plan. Finishing items are not included Only RCC, masonry and plaster are included. Note:

75. SAVE Up to Rs. 200 Per Sq. Ft. Home 269 Sq. Ft. For Rs. 2 Lacs Only. 3 Star Hotel Room For Rs. 3 Lacs Only. Transit Camp Room For Rs. 1 Lac Only. School Class-Room For Rs. 3 Lacs Only.

76. Advantages Of R.C.B. Method. Economy: As steel, cement, formwork, concrete & Labour required is almost half & due to simplicity of construction & speed, minimum saving is Rs. 200/- per sq. ft. Fire Proof: Due to concrete block & 3" cover to steel, rusting is minimized & such buildings are fire & bomblast proof. Durable:Concrete blocks are attractive, durable and have excellent thermal, acoustic properties. No repair like R.C.C. is needed in every ten years.

77. Earthquake: Load bearing concrete blocks can be designed to be wind, earthquake resistant too. Speed: No heavy equipment needed on site, less formwork, less steel so construction is simple, speedier & hence economical. Architecture: Ancient type of architectural elevation is also possible by R.C.B type of construction.

78. R.C.B. is Useful For Retaining Wall Bridge Abutment Bridge Pier Highway Culverts

79. CONCLUSION Considering Durability, Speed, Simplicity & Saving, 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.
