| Title of the article | The environmental rating of «carbonate» cements is low water demand and concrete based on them |
| Abstract. | Problem statement. To evaluate «carbonate» cements of low water demand and concretes based on them according to environmental indicators, calculated by the clinker capacity of binders. Results. Developed by the authors «carbonate» cements of low water demand with a clinker content of 20 to 70 % surpass standard cements in all technical parameters and can replace them in the production of concrete, while having the lowest «carbon footprint», assessed by the environmental rating proposed by L. Evans and M. Mutter. It is proposed to consider the environmental rating not only for cement, but also for cement concrete and structures made of it, covering their entire life cycle up to the stage of disposal of the dismantled object. The ecological index КцСО2 of «carbonate» cements of low water demand was calculated and it was shown that in comparison with European cements, also containing limestone additives, it is 2 times lower. Conclusions. The significance of the results obtained for the construction industry is to substantiate the use of «carbonate» cements of low water demand, as having the lowest content of cement clinker, which meets the most stringent environmental requirements for carbon dioxide emissions into the atmosphere. |
