The intensity of the alkali-silica reaction (ASR), a destructive interaction between alkalis and reactive SiO2 in materials containing Portland cement and aggregates, is usually assessed by the deformations of samples in an alkaline solution. With gravel aggregates cont...
The effectiveness of using ground granulated blast furnace slag (GGBS) to replace 40 % cement in the composition of pavement concrete is shown, together with a polymer chemical additive and a mineral additive activated by polycarboxylate polymers. The proper...

The history of the department of binder technology, established in 1920 in Petrograd, as well as theoretical and applied scientific research of its specialists.
In Q1 2020 1,636.0 kt of cement and 1,214.6 kt of clinker were produced by enterprizes — members of Ukrcement Association, which is 5.1 % more and 0.4 % less than in Q1 2019, respectively.
In Q1 2020 the country exported 25.5 kt of clinker worth about US$ 1,125 ...
The manufacture of cements bearing a high percentage of active additions is a trend that has been spurred by the benefits accruing from the reduction of clinker content. The availability of traditional natural pozzolans is ebbing, however, due to a decline in quarrying ...
