| titleOfInvention | A kind of surface modified superfine Stainless-steel fibre high impedance ultra-high performance concrete and preparation method thereof |
| abstract | A kind of surface modified superfine Stainless-steel fibre high impedance ultra-high performance concrete and preparation method thereof, belongs to building material technical field.The ultra-high performance concrete includes 50 ~ 300 parts of surface modified superfine steel fibre, 500 ~ 1500 parts of cement, 50 ~ 500 parts of mineral admixture, 1000 ~ 1800 parts of fine aggregate, 5 ~ 40 parts and 150 ~ 650 parts of water of chemical admixture according to mass fraction.The method are as follows: nano-silicon dioxide modified dose of preparation；The surface of ultra-fine steel fibre is modified；Concrete stirring and maintenance.The present invention carries out surface to ultra-fine steel fibre and grows SiO 2 Modification, increase surface roughness in terms of morphology, increase the coefficient of friction between fiber and matrix, Nano-meter SiO_2 is utilized in chemical aspect 2 High pozzolanic activity, the hydrolysis product of cement Ca (OH) with interface area 2 Secondary hydration occurs, generating hydrated calcium silicate gel C-S-H improves interface weakness zone.Its flexural strength reaches 25MPa or more, and resistivity reaches 20000 ohmcms or more. |
