Self-Compacting Concrete on the Basis of Local Materials of Azerbaijan

The deformation properties of self-compacting concrete, including the modulus of elasticity and shrinkage, are determined. As part of the research work, CEM II/A-P 42.5R (Azerbaijan), granodiorite crushed stone of 5–10 mm fraction from the Shamkir district of Azerbaijan, as well as crushed stone from gravel mined in the Kubinsky district were used as a binder. As a fine aggregate, natural sand, screening with a size modulus of 3.5, as well as silica as a mineral additive and SF-20 modifier to give the concrete high fluidity to increase segregation resistance and achieve strength and other construction and technical properties of concrete are used in all concrete compositions. The research studied the technological and rheological properties of self-compacting concrete using a V-funnel, L-box and J-ring. High-strength concrete was obtained on the basis of a self-compacting mixture of the appropriate composition. The main purpose of the research is to obtain self-compacting concrete mixtures. The compressive strength of concrete obtained on the basis of Velvelichay and Shamkir granodiorite rubble, after 28 days, was 67.1 and 69.8 MPa, respectively. It is shown that the use of superplasticizer contributes to eliminate corrosion problems in the manufacture of reinforced concrete structures by reducing the water resistance of concrete.
