FIELD: construction industry.
SUBSTANCE: invention relates to the field of construction, namely to the method for production of reinforced concrete. The technical task is to develop a method for obtaining high-strength concrete with a low cement content, reinforced concrete based on it with delayed corrosion of reinforcement. A method for preparing a concrete mix for reinforced concrete structures, including mixing cement, granite crushed stone of 5-10 mm fraction, quartz sand, superplasticizer additives, slag and water, characterized in that the slag is pre-ground together with calcium nitrate to a specific surface area of at least 4200 cm2/g, quartz sand is used with a size modulus of Msm: 2.3, and the superplasticizer is used on the basis of polycarboxylates with a reduced cement consumption: 2.1-4.2, wt.%.
EFFECT: expansion of the range of solutions for concrete mixes.
