  • Free water in cement slurry: Why is it critical? - by Wellcem

    High free water content is also often a sign of an unstable slurry with settling problems. More or less water – testing the cement. The natural water-cement mixing ratio is around 44% water by weight of cement. So if you have 1 kg of dry cement, the amount of water to get the best hydration and curing is 440 gr (or 0.44 liter).
