This study focuses on the nature of C-S-H in the early age hydration products. Early age hydration products of neat white Portland cement (WPC) paste, WPC with IM calcium chloride paste, WPC with O.IM calcium chloride paste, WPC with 20% malic acid paste, WPC with 20% sodium gluconate paste and tricalcium silicate paste at 2, 4, 6 and 8 hours were analysed by various techniques, namely SEM EDX, TEM EDX, MAS NMR, STA-EGA, XRD, FTIR and calorimetry. The morphology, chemical composition and nanostructure of hydration products, among which the most important is C-S-H, are obtained. Ti The nature and formation of C-S-H in early age are discussed in detail.
