  • 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.

    The adaptability of concrete admixture? Seven-step solution!
    The unsuitable performance is firstly that the slump of fresh concrete is small and the expansion is small, but the amount of water reducing agent is already quite large at this time. The popular saying is "unopenable"; secondly, the slump loss is large, Sometimes there is even false setting, that is, the cement slurry is very thin at the beginning of the mixing, but it quickly sticks and dries, and the workability of the concrete after the machine is very poor;

    The third step of the adaptability test is to find out the saturation blending value of the superplasticizer used for this cement. If two or more superplasticizers are mixed, the cement paste is passed through the total amount of the mixture. Test to find the saturation dosage point. The closer the amount of superplasticizer is to the saturated content of the cement, the easier it is to obtain good adaptability.
