R concrete for concrete products and precast concrete elements
R concretes with a proportion of recycled aggregates are standardized normal concretes which are allowed for use in Germany up to strength class C30/37. Because of the good technical properties and the ecological advantages, the article presents possible applications in the field of concrete products and precast concrete elements. Read part 1 of the paper.
R concrete with a proportion of recycled aggregates made from crushed concrete and crushed masonry in compliance with standards are standardized normal concretes which are allowed for use in Germany up to strength class C30/37. Unfortunately, they are only occasionally used in concrete construction and almost exclusively as ready-mixed concrete owing to the low degree of awareness and rather regional availability. Because of the equivalent technical properties and the ecological advantages with regard to conserving resources and saving of landfill volume, the article presents so-called R...
