In 2021, the holding's plants offer customers a number of new types of cement: Topkinsky Cement and Iskitimcement - CEM I 42.5N DP for the manufacture of concrete for road and airfield pavements, Angarsk Cement and Mining Plant - CEM II / A-G 32.5B, which replaced CEM II / A-Z 32.5B due to the transition to a new type of additive.
“Due to the COVID-19 pandemic, the construction season of 2020 was unstable: in July, when cement consumption in Siberia traditionally reaches its maximum, the market capacity of the macroregion immediately decreased by 10%, then gradually recovers. We hope that this will not happen in 2021. And we are always ready for an increase in demand - if there are more orders, plants of the holding will increase the production of high-quality building materials in short time,” emphasized Gennady Rasskazov, First Vice President of Sibcem.
