Heat-resistant Concretes for Low and High-temperature Aggregates

Accelerating scientific and technical progress is a very urgent task in the field of building materials production, in the field, which includes the introduction of new technologies and promising materials, the widespread use of local raw materials and production waste; the saving of thermal energy and material resources during the production of building materials; and the increase in the cost of products. Over the past few decades, in many countries around the world, refractory concretes have been widely used in the operation of thermal aggregates instead of existing expensive and scarce refractory materials. Heat-resistant concretes (for low and high-temperature thermal aggregates) were obtained, which are highly efficient building materials, using local raw materials (slag) and industrial waste (glass cullet, chamotte cullet). This makes it possible to save significant amounts of money on the transportation of materials. Volcanic slag was used as an admixture in concrete, which resulted in a smaller component of the material, simplification of the technology, and a reduction in the cost of the product.
