Effective refractory concretes

Abstract

As a result of our research, fire-resistant concrete samples were obtained, the compressive strength of the samples varies 6 to 18 MPa, the average density of the material is 680 - 1950 kg/m3, respectively. Tests of the products` resistance to temperature effects showed that when samples are heated to 800°C, mass loss ranges 1.2 to 7.8%. Such a composite material can be classified as special concrete, it can be used for the production of fire-resistant concrete.
