Concrete
is one of the important materials of the
construction industries. At present, due to
increase in a population, the demand for
infrastructure is increasing day by day. This
leads to increase in production of cement.
Currently, worldwide cement production is about
1.6 billion tons. This huge amount of production
leads to consumption of natural resources and it
is also harmful for environment. Large quantity
of waste by products are produced from the
manufacturing industries such as mineral slag,
fly ash, silica fumes etc. Cenosphere is a
byproduct obtained from the thermal power plants
generated by the burning of coal powder. It is
transported by the flue gases which can be
further collected by electrostatic precipitator.
This is a free flowing powder that comprises
hollow sphere, hard shelled and lightweight
which is collected from coal ash. This research
work deals with the partial replacement of the
cement with cenosphere in concrete at various
percentage, such as 0, 4, 8, 12, 16 and 20% by
mass of cement. The various experimental
investigations are carried out to determine the
compressive strength, split tensile strength and
flexural strength of concrete cube cured for the
period of 7 and 28 days. The results obtained
from the experiments with a suitable replacement
of cement with cenosphere are presented in this
study.
