Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%. | ||||||

Le mélange de mortier sec, à base d'un liant inorganique et le cas échéant d'agrégats naturels, d'agrégats artificiels, de fibres et d'autres adjuvants usuels pour le béton, est proposé spécialement pour la prévention et/ou l'élimination de dommages des surfaces des ouvrages en béton. Le mélange de mortier sec contient en plus un adjuvant granuleux pour le liant inorganique augmentant l'alcalinité et ayant une vitesse de réaction sensiblement plus faible que ce liant. Cette "réserve d'alcalinité" empêche une diffusion de CO2 et de SO2 de l'air dans le béton, ce qui s'oppose à la détérioration du béton. | ||||||
