According to BS 8007 (1987) and ASTM C 127-88 (1989), aggregate water absorption value should be less than 3% and 2.5%, respectively. The basalts are suitable for high strength concrete from the point of water absorption. The water absorption of the olivine basalt aggregates is lower than other basalts.

Basalt rocks are commonly used as construction materials such as aggregate in concrete and asphalt, rock filling in dams and breakwaters, crushed gravel in railway ballast and …

Basalt aggregate (BA) with a 3% water absorption, raw recycled aggregate and basalt (RRA), and improved recycled aggregate and basalt (PRA) were the main …

This research investigates the effect of basalt fiber (BF) on the fracture properties of recycled aggregate concrete (RAC). Three-point bending tests were performed on notched beams of BF -reinforced recycled aggregate concrete (BFRAC) at varying recycled coarse aggregate (RCA) substitution rates. The study aimed to …
