The effect of waste marble and basalt aggregates on the …
The mean values obtained from the basalt aggregate series (B0, B25, B50, B75, and B100) were determined as 50.74 and 51.28 kΩ.cm, respectively. When the waste marble and basalt aggregate HSSCC series were compared, higher electrical resistivity values were obtained in the waste marble aggregate series, albeit at very low rates.
