Assessment of the block strength of dispersely-armonized basalt fiber, complex-modified small-grain fiber concrete

Abstract

The article presents the results of a study on the impact strength of fibroconcrete with basalt fiber obtained on the basis of a complexally modified ash aggregate and "POLIMIX" superplasticizer cement binder. Based on the conducted experimental studies, it was established that during the volumetric hardening of fine-grained concrete with basalt fiber, as well as the complex modification of the cement matrix of basalt fiber concrete with ash filler and "POLIMIX" superplasticizer, an ultra-strong surface layer is formed in the composite, which creates a monolithic mineral enclosure, significantly improving all the physical and mechanical properties of the material.
