Published: — with international search report (Art. 21(3)) (54) Title: CONCRETE, A DRY MIXTURE FOR THE PREPARATION OF THIS CONCRETE, AND A METHOD FOR THE PREPARATION OF THIS CONCRETE (57) : The invention relates to fresh concrete which contains in 1 m3 135 to 250 kg of water, 135 to 400 kg of cement or 135 rl to 455 kg of a mixture of cement and substituents of cement in a ratio of cement to substituents of cement from 30:70 to 70:30, 28 to 52 kg of microsilica and 1000 to 2000 kg of aggregate with upper fraction of up to 16 mm, or up to 8 mm, whereby 70 to 100 % of this N aggregate is formed by brick or ceramic or mixed recyclate made from inert construction and demolition waste with a fraction of 0 to 7 r 16 mm, or 0 to 8 mm and/or concrete recyclate with a fraction of 0 to 16 mm, or 1 to 16 mm, or 0 to 8 mm, or 1 to 8 mm. A possible 71' remaining part of the aggregate - up to a maximum of 30 % by weight, is formed by natural aggregate with upper fraction of up to 16 mm or up to 8 mm. Another 0 to 30 % by weight of the aggregate may be made up of at least one known improving component which enhances thermal and/or acoustic and/or fire resistance properties of concrete and which is commonly used in standard concretes. The 00 invention also relates to a dry mixture for the preparation of this concrete, as well as a concrete product or a prefabricated element made from this concrete. In addition, the invention relates to a method for the preparation of this fresh concrete.
