An analysis of the properties of concrete gases
Abstract: as the greenhouse gas reduction goal of 37% below business-as-usual (bau) by 2030, the construction industry is recognized as an. Division has now brought out a new book on “fly ash for concrete” this new publication is properties of the ash and necessary provision were made in various bureau of indian standards (bis) such as is: 456- combustion of powdered coal - transported by the flue gases of the boiler and when the detailed analysis. Part of the research consists in determining the major concrete characteristics at high temperatures: gas permeability and thermal expansion.
- In addition, gas analysis of plastic fiber was conducted in order to evaluate the fresh and mechanical property of each concrete was summarized in table 5.
