Abstract :
In present construction industry sand is a
common building material used as a fine aggregate. The
availability of natural sand is being exhausted due to
rapid growth in construction activities. Also good quality
sand may have to be transported from long distances
adds to the cost of construction and energy consumption.
Hence it becomes inevitable to use alternative materials
for fine aggregate. Nowadays large quantity of stone dust
is produced as a by-product of crushing activities in the
stone crusher units. Also, stone dust produced from such
crushing zones appears as a problem for effective
disposal. It has limited application in construction
activities and a large amount of it is being dumped into
low-lying areas. In this study, the main concern is to
utilize the stone dust as a constituent for a mortar mix
and to carry out embodied energy measurements. For
this purpose, different mortar mixes are produced by
replacing natural and manufactured sand with stone
dust content. Stone dust passing by 150 microns is used
for sand replacement. Mortar specimens are cast and
investigated for compressive strength. To determine
embodied energy of mortar energy measurement studies
are carried out in a stone crusher unit located at
Jaysingpur, Maharashtra. The energy required for the
production and transportation of manufactured sand
and stone dust is calculated. This paper reports the
experimental study which investigated the influence of
the replacement of sand with stone dust and thereby its
effect on compressive strength and embodied energy. For
this purpose cement mortar cube was studied with
various proportions of stone dust as 0%, 5%, 10%, 15%,
20% and 25% by weight of sand. A comparison of
energy in different types of mortar mix has been made.
The experimental results showed that the replacement of
stone dust for sand was found to enhance the
compressive properties of mortar specimen. Use of stone
dust with manufactured sand for mortar preparation
can led to 8-10% energy savings. It has been Moreover
the substitution of sand by stone dust will serve the solid
waste minimization and waste recovery and beneficiating
the environment.
