Particle size growth of early hydrating cement - influence of water content and admixtures
During the hydration of Portland cement, basic changes in the properties of the whole system occur. Besides the extensive research concerning macroscopic, microscopic and chemical properties of Portland cement, relatively little is known about changes in the particle size distribution of the cement within the stages of hydration. Due to the formation of hydration product layers on the particle surface as well as to other effects, major changes in the particle size distribution of the hydrating Portland cement are detectable. This paper deals with changes in the particle size distribution of Portland cement in the early stage of hydration, which are verified via in-situ granulometric measurements. The influence of measuring technique, water content and the use of admixtures on measurement results will be shown.
