  • What is concrete slump
    What is concrete slump
    Concrete slump mainly refers to the plasticizing performance and pump ability of concrete. The factors that affect the concrete slump mainly include gradation change, water content, weighing deviation of the scale, and the amount of admixture, which are easily overlooked. Cement temperature, etc. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete.

    Eliminate concrete bubbles, super smooth concrete surface construction method! ((1)
    Concrete refers to a general term for engineering composite materials in which aggregates are cemented together by cementitious materials, and is widely used in civil engineering. Because it consists of solid phase, liquid phase, and gas phase, some bubbles will inevitably be produced after the concrete is poured. But the existence of these bubbles will not only affect the appearance of the project, but more importantly, it will have some hidden risks.
