Abstract

The results of analysis of heat-resistant concretes based on by-products of the metallurgical industry (blast-furnace and granulated slag) are presented. The data on the state of the matter as of 2022 and their evaluation are given. Based on the identified features of heat-resistant concretes based on slag aggregates, a new way of modifying their composition is proposed. An increase in residual strength of 75 % was achieved by introducing basalt fiber into the concrete composition. Test data of the obtained heat-resistant fiber concrete are given.

Key words:

heat-resistant concrete, fiber concrete, slag aggregate
