Title
(EN) DUSTING-INHIBITED CEMENT COMPOSITION IMPROVED IN STRENGTH
(FR) COMPOSITION DE CIMENT ANTI-POUSSIERE PRESENTANT UNE ROBUSTESSE ACCRUE
Abstract
(EN)
A cement composition which comprises 100 parts by weight of a cement, 0.01 to 0.1 part by weight of fibrillar polytetrafluoroethylene, and 0.001 to 1.0 part by weight of an alcoholic antifoamer and/or silicone antifoamer, is less apt to dust, and gives concrete or hardened mortar having improved strength.
(FR)
Cette invention concerne une composition de ciment renfermant, en poids, 100 parties de ciment, de 0,01 à 0,1 partie de polytétrafluoroéthylène fibrillaire et de 0,001 à 1,0 d'antimousse à base d'alcool et/ou d'antimousse à base de silicone. Ce ciment produit moins de poussière et donne un béton ou un mortier durci présentant une robustesse accrue.
