  • What is the difference between a self-loading concrete mixer and a forced concrete mixer?
    What is the difference between a self-loading concrete mixer and a forced concrete mixer?
    The difference between self-loading concrete mixer and forced concrete mixer is:
    1. The mixing tank works differently:
    In the self-loading concrete mixer, the mixing drum rotates at an appropriate speed; while the mixing drum of the forced mixer is fixed.
    2. Different mixing uses:
    Self-loading concrete mixers are mostly used to mix general plastic concrete, and mandatory mixers are mostly used to mix dry hard concrete and lightweight aggregate 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.
