Abstract
Abstract: The article examines the influence of the type of limestone aggregates from limestone deposits of the Crimea on the physical and mechanical properties of fine-grained concrete, dispersed-reinforced with fiberglass and basalt fiber.
Subject of research: physical and mechanical characteristics of dispersed-reinforced fine-grained concrete based on limestones of various genesis.
Materials and methods: limestones of various genesis and fine-grained concretes based on them, reinforced with glass fiber and basalt fiber, were used as objects of research. The physical and mechanical properties of concrete were determined by standard methods.
Results: experimental results have been obtained, indicating the production of high-quality dispersed-reinforced fine-grained concrete, depending on the type of limestone rocks.
Conclusions: the use of limestone aggregates of various genesis in the production of fine-grained concrete dispersed reinforced with fiberglass and basalt fiber allows to obtain a material with a compressive strength of 20.0 - 26.75 MPa and a tensile strength of 4.10 – 5.21 MPa.
