EXISTING CONDITIONS

AND

CONSTRUCTION

PRACTICES

The zone covers hilly region as well as substantial part of Indo-gangetic plane and falls under seismic zone IV. In the hilly areas there is abundance of stone and the planes are full of alluvial soil. The houses are built with soil blocks, bricks, stone walls and roofs are CGI sheets, burnt clay tiles, reinforced brick concrete and R.C.C.

INNOVATION OF

MATERIALS,

COMPONENTS

AND

TECHNOLOGIES

·        Instead of mud blocks for walling, stabilized clay blocks with cement-lime-bitumen shall be produced mud used. Stone block masonry.

·        In areas where flyash is available, units production for producing building components utilizing flyash for clay-flyash bricks or and flyash-sand- lime bricks.

·        In place of RR masonary, solid concrete blocks of 30x20x15 cm and 30x15x15 cm with designed concrete mixes using 50 mm aggregates I stone spalls  or hollow concrete blocks of 40x20x20 cm shall be used. The partition wall blocks shall be 30x10x10 cm hollow.

·        In Hilly area solid/hollow concrete block walls with RCC bands, as per 1.5. code, shall be used which will avoid the use of timber and provide easier / faster and better construction.

Foundation

·        For the stilts, precast RCC posts shall be used, instead of timber posts. The joists shall also be of RCC either in-situ or precast.

·        Burnt clay bricks in cm1:6

Wailing

·        Rat-trap bond walling with burnt bricks which saves 25% bricks and mortar in plastering can be used as filler walls in RC framed structure.

·        19 mm thick burnt brick wall for buildings upto 2 storeys provide around 20% saving in bricks and mortar and greater floor area for the same plinth area can be used or as filler wall in case of RC framed structure.

·        Single brick thick walls laid in cement mortar 1:6 as load bearing structure.

·        Hollow, concrete blocks or solid concrete blocks for walling instead of RR masonry saves in cubic content of masonry thereby reducing weight on foundations and achieving sailings in foundation as well as masonry walling. It will provide speedier construction and greater floor area for the same plinth area.

Lintels

·        75 mm thick precast RCC lintels, with or without sunshades, can be provided in brick or block masonry walls.

·        RC plinth bands, lintel bands and roof band using cement concrete M20 concrete.

Doors and

Windows

·        Braced and battened doors of secondary species timber with pivots at top and bottom can be provided with or without any frame.

·        RCC frames and shutter for doors and windows can be provided.

·        Ferrocement shutters for doors

·        Cement bonded particle boards, with or without frame can be provided.

Roofing

·        Precast RCC joist with prefab brick panels / RC plank / funicular shell / Precast Jackarch panel and concrete panels in roofs along with prefab brick panel system can be provided.

·        RBC/RCC in-situ may also be provided

·        Precast channel units of RCC or ferrocement especially for panchayat ghar/ school building/health centres/post office / bank can be provided.

·        AC/CGI sheets with purlins of steel/ RCC /ferrocement instead of timber can be used.

·        Precast RC I panel for sloping roof can be used.

Flooring

·        PCC 1 :2:4 flooring 25 mm thick over a base course of lean concrete (1:5:10) 75 mm thick

Sanitation

·        Single stack system of plumbing.

·        G.!. I PVC pipes for water supply.

·        CII PVC soil I waste pipes
