M . Tech. THESIS SYNOPSIS

INVESTIGATION OF SHEAR STRENGTH OF

CONCRETE BY REPLACE ENT OF COARSE

AGGREGATES AND FINE AGGREGATES BY

RECYCLED COARSE AGGREGATES AND

BOTTO ASH

CONCRETE WASTE

Concrete is the world’s second most

consumed material after water. About

48 million tonnes per annum solidwaste is produced in india ,which has

14.5 million tones from construction

waste. Only 3 used in emban!ments.

BOTTO ASH

ar*e amount of ash is bein*

produced in industry and specifically

in #ower #lants . #resently ,only partof it in form of 'ly ash is bein* used

in cement production and rest of ash

in of no use and hence disposed offhere and there causin* a maor threat

to the en6ironment.

BOTTO ASH AS

PART

IAL REPLACE ENT

TO FINE AGGREGATES

esearch wor! is *oin* on

worldwide for the udicial use of

bottom ash. One alternati6e bein*

wor!ed is its use as partial

replacement to fine a**re*ates in

concrete production

Pai!e K A " e#a$ %&'11(

Use of Recycled andSecondary aggregates inconcrete: Engineering

and environmentalconsiderations

Determination of consistency ofquality of recycled aggregatesgenerated from washing plants, show

that water quality aects of using RSAin construction are within the limitsset for natural aggregates !he eectsof RSA on the strength anddeformation characteristics ofconcrete and develop performancerelated approaches towards the

appropriate standardi"ation andspeci#cations of RSA in concrete

Assessment of RecycledAggregate $oncrete

$oncrete made with this type ofcoarse aggregates can havemechanical properties similar to thoseof conventional concretes and even
