NON-EFFLORESCING CEMENTITIOUS BODIES |
摘要 |
A non-efflorescing cementitious body is formed from sources of calcium aluminate, calcium silicate, calcium sulphate and reactive silica, these ingredients being present in such relative proportions that, upon hydration, both monosulphate (C<SUB>3</SUB>A.CS.12H) and hydrated alumina (AH<SUB>3</SUB>) are formed. Also disclosed is a hydraulic binder and a paste from which such bodies can be formed and a method for forming such bodies. In addition to exhibiting low efflorescence, these bodies retain satisfactory physical properties, especially good durability to natural weathering conditions. |
