Description d\u00e9taill\u00e9e (contexte, objectifs, etc.)<\/strong>\u00a0:<\/p>

Le b\u00e9ton est compos\u00e9 de ciment, de granulats, d\u2019eau et d\u2019adjuvants. L\u2019impact carbone du b\u00e9ton traditionnel CEM I (ou ciment Portland) est principalement d\u00fb \u00e0 celui du ciment. Les \u00e9missions du ciments sont dues \u00e0 celles du clinker (80% de calcaire et 20% d\u2019argile) :<\/p>

-La cuisson \u00e0 1450\u00b0C du Clinker (35% des \u00e9missions du clinker)<\/p>

-La d\u00e9carbonation du calcaire lors de la cuisson (65% des \u00e9missions du clinker).<\/p>

Pour r\u00e9duire ces \u00e9missions, il faut substituer une partie du calcaire pr\u00e9sent dans le clinker par des additions min\u00e9rales. Ainsi, les ciments \u00e0 forte teneur en clinker (CEM I et CEM II\/A > 80% de clinker) sont plus \u00e9metteurs que les ciments avec des additions min\u00e9rales venant substituer une partie du clinker.<\/p>

Nous cherchons donc \u00e0 privil\u00e9gier l\u2019usage du b\u00e9ton bas carbone (c\u2019est-\u00e0-dire avec une substitution du clinker par des additions min\u00e9rales).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Pour calculer le pourcentage de r\u00e9duction, il faut utiliser le facteur d\u2019\u00e9mission du b\u00e9ton \u00e9valu\u00e9 dans l\u2019EPD r\u00e9alis\u00e9 par votre fournisseur pour le type de b\u00e9ton qu\u2019il vous vend.<\/p>

    B\u00e9ton C35 45 CEM I D20 S4 XF1 remplac\u00e9 par du b\u00e9ton C35 45 CEM IIIB D20 S4 XA2 :<\/p>

    Empreinte carbone b\u00e9ton C35 45 CEM I D20 S4 XF1 = 270.4kgCO2e\/m3<\/p>

    Empreinte carbone b\u00e9ton C35 45 CEM IIIB D20 S4 XA2 = 113.86 kgCO2e\/m3<\/p>

    \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Gain = 156.54kgCO2e\/m3 soit une r\u00e9duction de 58%<\/p>
