| titleOfInvention | A kind of non-evaporating pressure PHC tubular pile concrete containing the strongest complex mineral material and preparation method thereof |
| abstract | The present invention relates to a kind of non-evaporating pressure PHC pile tube concrete, it is characterised in that described concrete material is as follows: Binder Materials；Described Binder Materials is made up of cement, rich calcareous material, Silicon-rich material, and in described Binder Materials in mass ratio, rich calcareous material accounts for 3.0%～8.0%；Silicon-rich material accounts for 25%～40%；Remaining part is cement；Water reducer, described water reducer is the 0.4%～0.8% of Binder Materials quality；Water, coarse aggregate, and fine aggregate；The ratio of mud of described concrete is 29%～31%, and sand coarse aggregate ratio is 33%～35%, and unit weight is 2480～2500kg/m 3 .Richness calcareous material is formed according to 1:4 or 1:6 is compounding by the present invention with Silicon-rich material, excited cement secondary hydration, improve its early strength, by atmospheric steam curing 6 hours, C80 strength grade requirement can be met, the performances such as PHC tubular pile concrete volume stability, anti-carbonation, steel bar corrosion, chloride-penetration resistance, freeze thawing resistance, acid corrosion-resistant, resistance to salt corrosion are improved and improve, improves later concrete endurance quality. |
