What Are The Main Ingredient In Green Cement? Is Green Cement Eco Friendly?
The industries across the globe
are continuously engaging themselves in enhancing environmental sustainability
and maintain a pollution free zone in the vicinity. The cement industry is one
of the major industries in CO2 emission, accounting for more than 5% of global
CO2 emission. The key reason behind the emission is the decarbonation of
limestone as well as the enormous amount of energy needed to heat the raw
materials.
Green Cement
Various initiatives have been
undertaken by the developed nations and developing economies across the globe in
order to manufacture high-class cement with improved energy and reduced CO2
emissions. Several organizations and cement manufacturers are continuously
focusing on the development of energy efficient concrete material and lower the
CO2 emission percentage. As the demand for commercial, residential and
industrial infrastructure is rapidly increasing across the globe, the demand
for energy efficient, low carbon content cement is also growing simultaneously.
Attributing to these two factors, the fly ash cement, slag cement, limestone
calcined clay cement, and recycled aggregates cement among others are gaining
substantial prominence in the current scenario.
The leading companies operating in
the field of green cement across the globe include LafargeHolcim, Heidelberg
Cement AG, Anhui Conch Cement Company Limited, Cemex S.A.B DE C.V, Votorantim
Group, China Resources (Holdings) Co. Ltd., Taiwan Cement Corporation, China
National Building Material Co., Ltd., Taiheiyo Cement
Corporation, and Ecocem among others.
