Abstract

Postupak za izradu betona visokih čvrstoća, n aznačen time, što obuhvata smešu cementa, kamenog agregata, superplastifikatora i vode u masenom odnosu 1:2:0,02:0,25 pri čemu je portland cement bez dodatka klase 45, a kameni agregat predstavlja drobljenu magmatsku stenu porfirske strukture sa veličinom zrna D max do 2mm; što se kameni agregat najpre suši do 2% vlažnosti i razdvaja prosejavanjem na dve frakcije od 0-1 mm i 1-2 mm koje se mešaju u masenom odnosu 1:0,7; što je superplastifikator formaldehidno-melaminski kondenzat koji se rastvara u vodi u masenom odnosu 1:12,5 i što se gornja smeša suvih i tečnih komponenata ugradjuje kao svež beton u kalupe ili oplate gde očvršćava 7 dana na temperaturi od 20В°C. Prijava sadrži još 4 zavisna zahteva.A process for the manufacture of high-strength concrete, n, comprising a mixture of cement, rock aggregate, superplasticizer and water in a 1: 2: 0.02: 0.25 weight ratio, wherein Portland cement is not added to class 45 and the stone aggregate is crushed magmatic rock of porphyry structure with grain size D max up to 2mm; the stone aggregate being first dried to 2% humidity and separated by averaging into two fractions of 0-1 mm and 1-2 mm which are mixed in a 1: 0.7 mass ratio; which is a formaldehyde-melamine condensate superplasticizer that dissolves in water in a 1: 12.5 mass ratio and that the top mixture of dry and liquid components is incorporated as fresh concrete into molds or formwork where it cures for 7 days at 20V ° C. The application contains 4 more dependent requests.
