Dry mixture for producing concrete, fresh concrete and method for producing fresh concrete
The invention relates to fresh concrete. The invention relates to a concrete admixture containing, in 1 m3, 50 to 300 kg of water, 135 to 400 kg of a binder or a mixture of 135 to 600 kg of a binder and at least one substitute thereof, 10 to 150 kg of a finely ground brick, ceramic, mixed or recycled concrete having a particle size of 5 to 250 microns and a specific surface area of 300 to 1500 m2/kg, or 10 to 150 kg of a finely ground brick, ceramic, mixed or recycled concrete having a particle size of 5 to 250 microns and a specific surface area of 300 to 1500 m2/kg, a mixture of mixed or concrete recycle with microsilica and/or at least one substitute thereof (wherein the content of finely ground recycle in the combination is at least 10% by weight) and 1000-2300 kg of aggregate. 45-100% of the aggregate consists of recycled materials from inert building and demolition wastes, and 0-40% of the aggregate consists of natural aggregate, and 0-40% of the aggregate consists of lightweight artificial aggregate and/or slag and/or slag and/or polystyrene and/or at least one organic filler and/or another component for improving the heat resistance and/or sound insulation and/or fire resistance of the hardened concrete. The aggregate pellets are coated and the pores of the aggregate pellets are filled with finely ground tiles, ceramics, mixed or concrete recycle or with a mixture of finely ground tiles, ceramics, mixed or concrete recycle with microsilica and/or at least one substitute thereof, and the cementing slurry is adhered to the aggregate pellets so treated. The invention further relates to a dry mixture and to a method for producing the concrete.
本发明涉及新拌混凝土，其在1 m3中含有50‑300 kg水、135‑400 kg胶结料或135‑600 kg胶结料与其至少一种替代物的混合物、10‑150 kg粒度为5‑250微米且比表面积为300‑1500 m2/kg的细磨的砖、陶瓷、混合的或混凝土再循环物或10‑150 kg粒度为5‑250微米且比表面积为300‑1500 m2/kg的细磨的砖、陶瓷、混合的或混凝土再循环物与微二氧化硅和/或其至少一种替代物的混合物(其中在该组合中细磨的再循环物的含量为至少10重量%)和1000‑2300 kg聚集料。45‑100%的所述聚集料由来自惰性建造和拆除废料的再循环物构成，0‑40%的所述聚集料由天然聚集料组成，并且0‑40%的聚集料由用于改进硬化混凝土的耐热性和/或隔音性和/或耐火性的轻质人造聚集料和/或炉渣和/或熔渣和/或聚苯乙烯和/或至少一种有机填料和/或另一种组分组成。涂布聚集料粒料且用细磨的砖、陶瓷、混合的或混凝土再循环物或用细磨的砖、陶瓷、混合的或混凝土再循环物与微二氧化硅和/或其至少一种替代物的混合物填充聚集料粒料的孔，并将胶结料浆粘附到如此处理的聚集料颗粒。此外，本发明涉及干混合物和用于制备该混凝土的方法。
