DETERMINATION OF STRENGTH CHARACTERISTICS OF HEAT-RESISTANT CONCRETE ON ALUMINA CEMENT

The article presents the results of experimental studies of the strength of heat-resistant concrete on alumina cement. The maximum size of grains of aggregates of sand and crushed stone, the results of cement tests, as well as the strength and deformation characteristics of concrete at normal temperature are given, which made it possible to calculate the strength of prototypes with high accuracy

The Development of Deformation in Concrete and Reinforcement in Concrete Beams Reinforced with Fiberglass Reinforcement

This article presents experimental data on the development of deformations in longitudinal reinforcement and concrete in the compressed zone of the section of bent concrete beams made of ordinary heavy concrete, equipped with fiberglass composite reinforcement under the action of transverse forces
