Abstract

The difficult-to-reconcile requirements of high plasticity of concrete mixes and high performance of road concrete can only be met by applying scientific principles of forming a concrete matrix structure with the highest possible aggregate grain density, with continuous granulometry, and the use of a complex of additives (microfillers and chemical additives with plasticizing and air-entraining properties (to create reserve porosity)). To achieve this goal of forming a concrete matrix structure with the highest possible aggregate grain density, patented methods and computer programs developed at the Department of Production of Building Materials and Structures (PBS) TvGTU were used.
