CONSTRUCTION TECHNIQUES MUD BLOCK STRUCTURES • • • • • • •
Unburnt sun-dried bricks for walls. Economical One side of wall is terracotta tile to make exterior wall water resistant Fly ash bricks for columns and bars Bamboo paneled doors and window shutters IPS flooring with colored oxide Foundation- un-coursed rubble masonry with boulder murrum filling is laid to prepare a flat ground. • Mud block wall is rain proof and rodent proof. No need for any other binding material • No steel and wood is used for roofing. The roof consists of a series of arches to be placed as a formwork from the conical tiles made out of burnt clay inserted into one another
WATTLE AND DAUB UNIT • • • • • • • •
Cement is used as stabilizer. Foundation based on stilts and random rubble masonry. Flooring of verandah made from locally available wood. Columns constructed using stabilized rammed earth block technique employing ‘ram rod’ technique. Walls made of bamboo mats plastered with mud or lime mortar. CGI sheet roofing over space frame truss instead of wood. Bamboo CGS can be used. Roof water harvesting shows syntax water tank connected to a cost effective sanitation model. The structure is totally earthquake resistant as vertical and horizontal bands are provided. TO HAVE VERTICAL REINFORCEMENTS, PVC PIPES ARE PLACED AROUND THEM AND CONCRETE IS POURED.
BRICK PANEL HOUSE • Use of brick panels for roofing. • Prefabricated brick panel and partially pre-cast joists require burnt clay bricks, cement, sand, coarse aggregate and reinforcing steel as major raw materials. • No major plant, equipment and machinery is required. • The brick panels are durable, leak-proof, fire-resistant, thermal-resistant, less noisy in rains and provide vertical expansion. • They are very cost-effective and generate employment opportunities in rural areas for masons/labor. ½ brick walling and brick column – Cost effective as it is used in between columns. Filler slab – Reduce the cost of RCC. Exposed brick work – Save plastering costs. Pre-fab panel roofing – saves on shuttering costs. Hollow wall construction – provide thermal insulation. Brick Jaali – saves on cost of window. Exposed brick parapet.
RAT TRAP BOND CONSTRUCTION • • • • • • • •
Random rubble arch foundation. Rat trap bond wall that saves 25% bricks and cement. Brick window jaalies. Filler slab roof. Non-erodable mud plaster up to sill level. Use fair face of the bricks in patterns to avoid plastering. Mud and brick bats flooring in different rooms. Kadapa slabs for shelves.
BAMBOO HOUSE • Bamboo is a versatile construction material which is affordable, durable and very suitable for earthquake prone regions. It is a light weight, long lasting and renewable building material • In case of earthquakes, bamboo house won’t cause any death if it collapses and is easy to mend and repair. • The use of these boards and other bamboo products makes the house construction not only cost effective but also offers exotic designs. • • • • • • • • • •
Eco-friendly structure. Light in weight. Wooden stilts and bamboo mat flooring. Self sustaining bamboo plantations – livelihood initiative for rural areas. Use of bamboo – columns, walling, roof framework and corrugated roofing material. User friendly in earthquake prone areas of Northeast and Andaman & Nicobar Islands. Exotic interior décor. Water resistant walls with cement plastering. Fire resistant with CuSO4 chemical treatment.
STONE PATTI CONSTRUCTION Climate control only influenced the design adopted-a central courtyard surrounded by construction of high walls with a balcony and small wind apertures to allow air circulation as well as preventing dust blow-ins during sandstorms. Main features • Stone Patti flat and sloping roof-no steel and centering and shuttering. • Reconstituted cement concrete blocks masonry used for walling. • Spacious courtyard and roof water harvesting facility. • Solar lighting facility. • Climate control due to providing of thick walls. Material required • Sand • Cement • Boulder stones • 6 to 12 mm aggregate • 15 to 20 mm aggregate • Water
