Abstract
The proposed invention relates to the building materials industry and may be used for production of pre-fabricated ferro-concrete items and making of monolithic constructions.At the base of the invention is placed the problem of making concrete mixture with higher durability during the pressure and exclusion of cement expenses.The proposed concrete mixture includes binding material, lime filler and silicic component.The invention contains the following new elements: - as binding material is used the pounded product of burnt granulated mixture of lime waste with dimensions of 0,1 - 1,25 mm and flying ashes or ashes-slag waste ]n ratio 0,5-0,6 under the following components correlation (mass %):the mentioned binding material - 10-15flying ashes or ashes-slag waste - 10-25.
Quick-setting and quick-hardening hydraulic binders and mixtures of binders containing them, preparation thereof and utilization for the preparation of mortars and concretes
