advantages and disadvantages of vacuum dewatering concrete - MITHUNMATHEW - 08-16-2017
Water-cement ratio is detrimental for concrete. We always try to restrict the water-cement ratio in order to achieve higher strength. The chemical reaction of cement with water requires a water-cement ratio of less than 0.38, whereas the adopted water-cement ratio is much more than that mainly because of the requirement of workability. Workability is also important for concrete, so it can be placed in the formwork easily without honeycombing.
