| description | An improved freeze-thaw durability cementitious composition is provided that uses' at least partially degradable polymeric particles that are blended directly into the cementitious composition mixture . The degradable polymeric particles provide void spaces in the cementitious material matrix, and such void spaces act to increase freeze-thaw durability of the cementitious material . Preferred polymers are polylactic PLA or polyglycolic PLG acid.
L'invention concerne une composition à base de ciment à ténacité améliorée au gel-dégel qui utilise au moins partiellement des particules polymères dégradables qui sont directement mélangées au mélange de compositions à base de ciment. Les particules polymères dégradables fournissent des espaces vides dans la matrice de matière à base de ciment, et ces espaces vides agissent de manière à augmenter la ténacité au gel-dégel de la matière à base de ciment. Parmi les polymères préférés, on note un acide PLG polyglycolicque ou un acide PLA polylactique. |
