Role of Concrete in Construction | SISTec Ratibad |
Concrete is the most necessary material used abundantly in
the construction Industry almost in all fields like Buildings, Nuclear Power
Plants, Highways, Dams, Bridges, and many more.
Due to industrialization and exorbitant
infrastructure development, concrete ranks next to need in the world after food
and water. Concrete mainly constitutes of cement, coarse aggregate (CA) and
fine aggregate (FA), in which cement is the major component which acts as a
binding material.
Cement industry produces carbon dioxide (CO2) significantly up to 5% of manmade emissions because of
chemical reaction and fossil fuel during manufacturing. Cement Corporation
India Ltd. in its 53rd annual report
2016-17 mentioned cement production of nearly 7.91 Lac MT in India. Research
articles mentioned each tone of cement production emits nearly 1 ton of CO2.
In order to reduce CO2 emission extensive research is going on in can be
done by;
1) Altering the components of cement
during manufacturing
2)
Reducing cement percentage in concrete.
3)
Partial or full replacement of cement by fly ash, glass waste, red mud, burnt
clay, geo-polymers etc.
Recently geo-polymer increased attention
of researchers and engineers as a sustainable alternative of cement. Geo-polymer
is a composite, synthesized using aluminosilicate material in an alkaline
medium, having 80% less production of greenhouse gases. Although engineering
and fire resistant property of geo-polymer is quite good with sustainable
durability. Geo-polymer also doesn’t need water curing, in all above respect
geo-polymer composite have possibilities to take place of cement, as
alternative eco-friendly material.
Sagar Institute of Science & Technology (SISTec) Ratibad working in this field with aim to reduce the
negative effect of concrete in the environment. With state of the art
literature and lab experiments, students under
the mentorship of faculties Department of Civil Engineering working on various live projects additionally
accomplishing internships to attain industry exposure.
