Abstract

Oppfinnelsen angår fremstilling av betong-takstein med øket tidlig styrke. Dette oppnås spesielt ved å innbefatte knust avfallsbetong i den sementholdige blandingen. Den økte styrken oppnås f.eks. hvis (i) knust avfallsbetong benyttes som en erstatning for tilslag; (ii) knust avfallsbetong benyt- tes som et kjernedannende middel; og (iii) knust avfallsbetong graderes slik at det kan benyttes for å erstatte tilslag og bevirke kjernedannelse.The invention relates to the manufacture of concrete roof tiles with increased early strength. This is particularly achieved by including crushed waste concrete in the cementitious mixture. The increased strength is achieved e.g. if (i) crushed waste concrete is used as a substitute for aggregate; (ii) crushed waste concrete is used as a nucleating agent; and (iii) crushed waste concrete is graded so that it can be used to replace aggregates and cause nucleation.
