Influence of nano- and micro-silica additions on the durability of a high-performance self-compacting concrete

The main purpose of the research is to examine the effects of binary and ternary mixtures of nSi and mSi on the durability of a high-performance self-compacting concrete (HPSCC). Compressive strength at 28 days, accelerated carbonation processes after 60 and 200 days of exposure to CO2, resistance to freeze-thaw cycles and capillary suction coefficient, were analyzed. In addition, microstructural characterization was carried out by Mercury...
