ABSTRACT:
Concrete is most widely and commonly used in construction. The raw material production of concrete has
certain harmfull effects on environmental. The aggregate element in concrete occupy 60-70% of the total volume. So
that the production of fine and coarse aggregate demand is increased now days. The aim of our project is to
overcome the demand of the raw materials. This is an urgent need to find alternative or green materials of concrete
to preserve and protect our natural resources for future, by replacing them partially or fully to achieve sustainable
development in concrete industry. This paper is mainly discusses the naturally available river pebbles, quarry dust
as partial replacement of coarse and fine aggregates. The study evaluates the strength of hardened concrete by
partially replacing coarse and fine aggregates by various percentages for M30 grade of concrete. Concrete mixes
with 0%, 10%, 20%, 30% replacement of river pebbles and quarry dust in our study. The mix proportion is done as
per IS: 10262-2009 and IS 456-2000. The properties of fresh and hardened concrete were studied on the mixes
considered. The results showed that strength properties and hence the use of river pebbles could be considered for
future concrete.
Keywords: River pebbles, Quarry dust, coarse aggregate, fine aggregate.
INTRODUCTION:
Concrete is one of the major construction
material being utilized worldwide. Concrete
is made usually by proper proportioned
mixer of cement, fine and coarse aggregate.
Continuous extraction of sand from river
causes environmental issues, along this
email issues the cost of the sand is
increased. To overcome these problems the
usage of an alternative material has required.
The place where the pebbles are largely
found must be identified and can be used to
replace the river sand since they give much
positive results when compared to other
alternative material. The reuse of the
pebbles will help to save cost conserve
limited resources and ultimately protect the
environment. Due to heavy increase in
construction activities, the crushed granite
stone which are the conventional coarse
aggregate is under depletion thus causing
shortage. The sand activities have resulted in
large number of environmental and social
problems. To meet the global demand of
concrete in the future, it is becoming a
challenging task to find suitable alternative
construction materials which can fully or
partially replace the natural aggregate
without affecting the property of concrete
make green concrete for sustainable future.
In India almost civil engineering
construction are carried out using coarse
aggregate. Due to heavy increase in the
construction activities, the crushed granite
stone which are the conventional coarse
aggregate is under depletion and also, now-
a-days on acute shortage of this material is
experienced. The strength of the concrete is
determined by replacing the main concrete
