Abstract

The dissolution of olivine in acid is an interesting alternative route to produce nano-silica because of the low cost of raw materials and the low energy requirements. The optimum replacement level of olivine nano-silica in conventional vibrated concrete is around 5% by volume resulting in: 1) a compressive strength increase of 20 %; 2) a CO2 emission reduction of 3 %.
