•The hydration products of pure C3S and nano-SiO2 at 80℃ were studied.•The optimum amount of silicon material at 80℃ differs from that at high temperature.•Decalcification will decrease the Ca/Si of hydration products.•Hight Ca/Si products can be converted into low Ca/Si products by nano-SiO2. The h...
