The effect of coarse basalt aggregate size and resulting powder content change are evaluated. Furthermore, the mineral admixture effect, interaction between aggregate and steel fibre are analysed and discussed. The results show that the optimal proportion of powder is 5% of micro-silica and 20% of limestone powder by mass of the total powder.
