Insufficient frost resistance of road concrete is one of the main reasons for the low average service life of highway bridges and the rapid deterioration of paving slabs, curbs, etc. The well-known criteria for producing highly frost-resistant concrete - a water-ceme...
The rheological properties of concrete mixtures are crucial for additive construction technologies. Methods for ensuring the required properties vary depending on the method of material preparation and feeding to the extruder: ready-to-use or dry concrete mix may be ...

The article examines the potential use of plant-based waste in cement concrete. It is shown that these wastes are used in cement concrete in several ways: as a dispersion-reinforcing additive, an energy-efficient filler, an additive that regulates the rate and heat o...
This article examines the potential use of fatty acids as grinding aids for Portland cement clinker. The data are presented on the influence of certain fatty acids, butyric, stearic, and oleic, on the clinker grinding kinetics, the grinding fineness of the resulting ...
