Characterization of early pozzolanic reaction of Calcium Hydroxide and Calcium Silicate Hydrate for Nanosilica modified cement paste.
This study intends to investigate the early pozzolanic reaction of Nanosilica (nS) modified cement paste (NMCP) by the characterization technique of Calcium Hydroxide (CH) and Calcium Silicate Hydrate (C-S-H ) using Fourier Transform Infrared Spectroscopy (FT-IR). NMCP samples were prepared with w...
