摘要:
The present invention concerns a hydraulic binder comprising a ground blast furnace slag in an amount comprised between 30% and 95% by mass on the binder, Portland cement clinker in an amount equal to or greater than 5% by mass on the binder, and at least one sulphate as activator, characterised in that said slag has the following properties and composition by mass: grinding fineness greater than 4000 cm2/g Blaine glass content greater than 80% SiO2: 30-40% Al2O3: 9-13% CaO: 34-42% with a (CaO+MgO)/(Al2O3+SiO2) ratio greater than 1; and in that said sulphate is contained in a total amount, expressed as SO3, comprised between 0.6% and 4.5% by mass on the binder.
摘要(中):
本发明涉及一种水硬性粘合剂,其包含在粘合剂上为30质量%至95质量%之间的粉碎高炉渣,在粘合剂上为等于或大于5质量%的波特兰水泥熟料,以及 至少一种硫酸盐作为活化剂,其特征在于所述炉渣具有以下特性和质量组成:研磨细度大于4000cm2 / g Blaine玻璃含量大于80%SiO 2:30-40%Al 2 O 3:9-13%CaO:34 -42%,(CaO + MgO)/(Al2O3 + SiO2)比大于1; 并且所述硫酸盐的含量以SO 3表示,在粘合剂上的含量为0.6〜4.5质量%。
