Studies on the effects of quarry dust on concrete have been conducted all around the world[12, 13]. The impact of partial sand and cement substitution on the compressive strength of concrete was investigated[12, 14]. The effects of substituting sand with quarry dust (20, 30, and 40%) on the properties of fresh and cured concrete were explored[15].

Physical Properties and Microstructure of Concrete with ...

The gradual substitution of sand with basalt dust leads to the sealing of aggregate composition, which results in lower air content in the concrete mix and thus a lower porosity of hardened concrete. Along with the increased basalt dust content in the sand mass, the increase in concrete mixture density is observed.
