How To Determine Whether The Concrete Admixture Is Excessive Or Insufficient, Or Whether The Water Content Is Too High Or Too Low？

     By assessing the concrete's condition,If there is too much water, the concrete usually does not settle at the bottom, and the surface of the aggregate is coated with mortar, allowing normal pumping and construction even without bare stones. However, with high slump, floating slurry may be accompanied by bleeding.

    If the concrete admixture is excessive, the concrete will slump and segregate, with the aggregate not being adequately coated by the paste, appearing shiny. When scooped, it will feel sticky and heavy, and stopping the pump may easily cause pipe blockage.

    If the water is sufficient but the concrete admixture is insufficient, the concrete will lift without sticking, but it will have poor fluidity and appear unnatural, relying mainly on gravity for flow.

    If the added concrete admixture dosage is sufficient but the water content is low, the concrete appears shiny but has a slow flow rate, slightly poor workability, and feels more viscous and heavier when scooped up.

Only with an appropriate water content and the proper dosage of concrete admixtures can concrete with excellent workability be prepared.
