Title (EN) HYDRAULIC INORGANIC COMPOSITION
(FR) COMPOSITION HYDRAULIQUE INORGANIQUE
Abstract: front page image
(EN)A hydraulic inorganic composition belonging to high-content sulfate slag cements and comprising: (a) water-granulated blast furnace slag fine dust... about 80 parts by weight (b) light-burned anhydrous gypsum or hemihydrate... about 20 parts by weight (c) a mixture of at least one compound selected from the group consisting of NaOH, KOH, Ca(OH)2, CaO, Na2CO3, K2CO3 and CaCO3 and at least one compound selected from the group consisting of Mg(OH)2, Al(OH)3, MgO, Al2O3, NaCl, KCl, CaCl2, MgCl2, AlCl3, Na2SO4, K2SO4, MgSO4, Al(SO4)3 and MgCO3 with a mixing proportion by weight of 1:1 - 1:6... 0.1 - 5.0 parts by weight. A hydrated and cured product of this composition is high-early-strength, light in weight and high in mechanical strength with suffering no weathering. Upon curing, it undergoes volume expension.
(FR)Une composition hydraulique inorganique appartenant aux ciments de laitiers a haute teneur en sulfate et comprenant: a) de la poussiere fine de laitier de haut fourneau granulee a l"eau ... environ 80 parties en poids b) gypse anhydre ou hemihydrate legerement calcine ... environ 20 parties en poids c) un melange d"au moins un compose choisi parmi le groupe constitue par NaOH, KOH, Ca(OH)2, CaO, Na2CO3, K2CO3 et CaCO3 et au moins un compose choisi parmi le groupe constitue par Mg(OH)2, Al(OH)3, MgO, Al2O3, NaCl, KCl, CaCl2, MgCl2, AlCl3, Na2SO4, K2SO4, MgSO4, Al(SO4)3 et MgCO3 avec une proportion de melange en poids de 1: 1 - 1: 6. 0,1 - 5,0 parties en poids. Un produit hydrate et durci de cette composition presente tres tot une resistance elevee, est leger et presente une resistance mecanique elevee sans souffrir des intemperies. Lors de son durcissement il subit une expansion en volume.
