water-cement ratio

A study on the influence of polycarboxylate-type superplasticizers on the physical and technical properties of fine-grained concrete was conducted. The proposed concept involves creating high-quality, high-strength concretes based on modified cementing systems characterized by improved construction and technical properties.

A new competitive class of grouting materials has been created. These lightweight grouting materials (LGM) with a density of 1370–1650 kg/m3 consist of oil-well Portland cement PCTI-100, fine powder of PE grade (a by-product of fireclay production from kaolin), acidic fly ash from state district power plants, and lime dust (a by-product of lime production). The composition of the products formed during LGM hydration was clarified by X-ray phase and differential thermal analysis.
