Optimization of the Composition of Segregation-Resistant Self-Compaling Concrete Mixtures and their Based Concrete
Abstract: The article considers the influence of the mineral additive of the Zuevskaya TPP ash and slag mixture, the viscosity modifier SCC-10 and the superplasticizer Sika ViscoCrete 5-600 N PL on the slump, fluidity of self-compacting concrete mixtures and the strength of concrete at an early and design age. Optimization of the composition of concrete mixes was performed using a full three-factor experiment. The areas of optimal compositions of concrete mixtures were determined by the content of mineral and chemical additives, which ensure the production of concrete mixtures with a slump index for the cone flow diameter of 588 mm (class SF1), as well as concrete with a compressive strength at the design age of 38 MPa. The studied compositions of self-compacting concrete mixes are recommended to be used for non-reinforced or low-reinforced concrete structures – floor slabs, pipelines, tunnel linings, foundations, which are subject to high requirements for surface quality and do not require additional processing.
Keywords: self-compacting concrete, industrial wastes of Donbass, viscosity modifier, superplasticizer, optimization of concrete composition.
