Les fibres mono-filament sint\u00e8tiques i de cel\u00b7lulosa treballen per evitar la retracci\u00f3 pl\u00e0stica durant les seves primeres 12 hores de vida. A partir de llavors, el m\u00f2dul el\u00e0stic del formig\u00f3 \u00e9s m\u00e9s gran que el de les fibres sint\u00e8tiques i de cel\u00b7lulosa per la qual cosa deixen de ser efectives. A m\u00e9s, absorbeixen aigua i, per tant, varia la relaci\u00f3 aigua-ciment en la barreja de formig\u00f3.<\/p>\n

En canvi, la fibra de vidre Anti-Crak HD 12<\/a> t\u00e9 una major cohesi\u00f3 i resist\u00e8ncia mec\u00e0nica<\/strong>, de manera que constitueix un refor\u00e7 m\u00e9s efica\u00e7 per a la retracci\u00f3 pl\u00e0stica. Aquesta fibra no absorbeix aigua i, per tant, no varia la relaci\u00f3 aigua-ciment en la massa de formig\u00f3.<\/p>\n

Algunes de les caracter\u00edstiques<\/a> m\u00e9s destacades de la fibra de vidre Anti-Crak HD 12<\/strong>, a part de la seva funci\u00f3 principal de prevenir i controlar la fissuraci\u00f3 del formig\u00f3, \u00e9s que proporciona una r\u00e0pida dispersi\u00f3 en mono-filaments de refor\u00e7, s\u00f3n filaments completament invisibles a la superf\u00edcie i millora la vida en servei del formig\u00f3 a causa d'una major homogene\u00eftat de la matriu.<\/p>\n

Tamb\u00e9 mitiga el risc de fissuraci\u00f3 per retracci\u00f3 pl\u00e0stica i evita que es formin les primeres microfisures en el formig\u00f3.<\/p>\n

A m\u00e9s, permet una f\u00e0cil aplicaci\u00f3 i \u00e9s bombejable des de qualsevol al\u00e7ada.<\/p>\n","protected":false},"excerpt":{"rendered":"
