The effect of mineral additives on the development of alkaline corrosion in Portland cement concrete with reactive gravel aggregate

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...

Paving concrete containing ground granulated blast furnace slag

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...

Foam concrete from Portland cement clinker and natural mineral raw materials of the Arctic zone of Russia

Wall materials of stable quality are required for the construction of facilities in the Arctic zone of Russia. Portland cement-based foam concretes produced by co-grinding imported clinker with local active mineral additives were developed to meet this requirement. Usin...
