In the present study, chemical mapping on the hydration process of cement paste with water-to-cement (w/c) ratio of 0.60 was implemented by Raman spectroscopy (RS). The RS was applied to study the paste from 12 hours after mixing to 28 days. Cement ingredients and hydration products, including calcium silicates (C3S and C2S), calcium hydroxide (CH), and ettringite, were quantitatively studied. From...
