Based on an analysis of the existing regulatory framework, the requirements of which apply to cement and concrete, on the example of technology for manufacturing vibropressed products, there have been identified restrictions on the use of cements with slag for their production. It has been determined that the level of standardization development in the subject area under consideration does not correspond to modern scientific achievements and the results of accumulated practical experience. As a result of investigation of vibropressed paving slabs made on the basis of cements containing slag in an amount of 15 %, it has been found out that all quality indicators correspond to the standardized level. This confirms the need to amend the regulatory framework for vibropressed products regarding the use of cements containing slag (at least 15 %).
