Influence of Particle Size on the Early Hydration of Slag Particle Activated by Ca(OH)2 Solution

Authors: Zhijun Tan, Geert De Schutter, Guang Ye, Yun Gao, Lieven Machiels Abstract: This paper investigates the influence of slag particle size on its hydration speed at particle level in the early age. Slags were separated with sieves into groups of different size fractions, considering a wide range of sizes. The chemical compositions of each […]

What can you do using cement? Funny stuff made of cement

It is well known that cement is the most used construction material in the world. In the mind of most of people, cement is a kind of grey powder and only used as construction material, to build gardens, bridges, road etc. However, we can do more with cement, here are nice pictures showing some stuff […]

The Influence of Slag on the Hydration of Cement

These following conclusions are summarized from the work of Kocaba’s PhD thesis. alite: no influence is shown on the consumption of alite measured by XRD. belite: the substitution of cement by both slags seems to result in a delay in the hydration of belite in the first days. aluminate phase: there is a filler effect […]
