Construction and Design of Multistorey Building-04

BINDING MATERIALS

Chicken wire mesh between brick masonry and concrete

Connection of pipes with concrete

Chicken wire mesh in conduits through concrete

WATER PROOFING

Water proofing has remained as an unsolved complex problem

Use of plasticizers, super plasticizers, air-entraining agents helps in reducing the permeability of concrete by reducing the requirement of mixing water, hence can be also be regarded as waterproof material.

Some of approved water-proofing compound by the company

are:- pidilite, cico, fosroe, baushimine, unitile.

Water-proofing cement paint:- super snoweem

WATER PROOFING IN GARDEN AREA

For water proofing in garden area the soil is first leveled and then rammed to achieve the maximum density

The PCC is then laid down mixed with tape Crete (a water proofing compound)

After PCC the plaster of fibrous material is done. the bituminous sheets are laid by heating it with the welder. On

those sheets the drainage pipes are laid down with suitable slope and these pipes are covered with geo-fabric sheets.

Again the plaster is done. On the plaster the 40 mm aggregates are laid.

On the aggregate the geo-fabric sheets are laid down on which the sand is placed & on the sand the soil ,along with fertilizers, is placed on which the gardening is done for the non tower area.

INTRODUCTION/BENEFITS

Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons

allows longer clear spans, thinner slabs

lower overall building height for the same floor-to-floor height.

allows a high degree of flexibility in the column layout, span lengths and ramp configurations
