Despite its popularity and profitability, the cement industry faces many challenges due to environmental concerns and sustainability issues [3]. In 2011, we used approximately 3.6 million tonnes of the stuff within the construction industry the problem being that for every tonne of cement produced, one tonne of CO2 is also produced. Apart from fly ash, green cement also uses blast furnace slag which can produce harmful environmental effects if it is simply discarded. Moreover, in the medium term, establishments that could no longer manage to break even would be forced to close down and this would discourage private investors. Presently, due to effective pollution management, emissions from cement plants are reduced. The use of cement in structural applications can be decreased by using by product cementitious or pozzolanic material as a cement replacement. Excluding consolidation effects, cement and clinker sales volumes decreased by 3.8%. (Lisa J. Hanle, n.d.) This shows that despite all the positive effects cement has on society, it still poses a significant threat to the environment and production should be controlled in order to prevent climate change from worsening even further.
