Effect of particle size on the hydration kinetics and
Impure tricalcium silicate (Alite C3S) is the most important and abundant phase of Portland cement. It reacts quickly with water to give calcium hydroxide (CH) and calcium silicate hydrate (C-S-H) which is the most important phase for strength development. It is well known that the C3S particle size distribution plays an important role on the hydration kinetics microstructural development

This investigation was made to examine how the particle size of lime influence the properties of calcium hydrosilicate materials. Quicklime was sorted in three fractions 0-1 mm 1-11.2 mm and 11.2.-22.4 mm. Slaked lime putties were prepared in the laboratory by mixing lime fractions and deionized water under vigorous stirring. The C/H ratio was 1 8.
