HYDRAULIC COMPOSITION WITH LOW CLINKER CONTENT |
| 摘要 |
A hydraulic binder including in parts by mass:
(a) 40 to 70 parts of a Portland clinker;(b) 30 to 60 parts of fly ash;(c) optionally up to 30 parts of an inorganic material other than clinker or than fly ash;(d) 2.5 to 15 parts of an alkali metal salt expressed in parts of equivalent-Na2O relative to 100 parts of fly ash; and(e) 2 to 14 parts of sulphate expressed in parts of SO3 relative to 100 parts of clinker;the fly ash having a Dv97 less than or equal to 40 μm, and the sum of (a), (b) and (c) being equal to 100. |

1. A hydraulic binder comprising in parts by mass:
(a) 40 to 70 parts of a Portland clinker; (b) 30 to 60 parts of fly ash; (c) optionally up to 30 parts of an inorganic material other than clinker or than fly ash; (d) 2.5 to 15 parts of an alkali metal salt expressed in parts of equivalent-Na2O relative to 100 parts of fly ash; and (e) 2 to 14 parts of sulphate expressed in parts of SO3 relative to 100 parts of clinker; the fly ash having a Dv97 less than or equal to 40 μm, and the sum of (a), (b) and (c) being equal to 100. |
