Influence of Added Silicon Oxide on Properties of Slag-based Synthetic Stone Casting Products

https://doi.org/10.18412/1816-0395-2023-7-24-29

Abstract

The study concerned the of obtaining stone-cast products from unmodified blast-furnace slag from Severstal PJSC and its mixture with river sand as a source of silicon dioxide. Mechanical characteristics, surface morphology, cutting microstructure and phase composition of products resulted from blast furnace slag and sand were studied. It was shown that when casting synthetic stone in an electric arc furnace without using a controlled cooling mode, it was possible to obtain a slag casting, the structure of which from chain silicates has a density of 2.9–3.0 g/cm3 and a compressive strength of 44.0–71.4 MPa.
