Concrete has long been an indispensable part of urban prosperity. Concrete construction can be seen everywhere, such as road construction, subway bridges, tunnel foundation pits, etc., but there are many types of machinery and equipment involved in the construction process. Batching machine, mixer, conveying equipment, molding equipment, etc.

When the poured concrete needs to be completed before its initial setting, if there is initial setting during the pouring, it is necessary to carry out strong mixing work on the concrete so that it can return to a flowing state, so that it can enter the mold, and If segregation occurs, it needs to be stirred again.

The height of concrete pouring should be controlled well, and the pouring height should be controlled within 2m to ensure the proper quality of concrete.

If the concrete in the vertical direction is poured, it is necessary to fill the bottom of the cement mortar with about 5~10cm in advance. Note that the cement mortar used at this time must be the same as the cement mortar used in the pouring, so as to reduce the concrete strength and affect the overall effect.

When pouring a large-scale construction surface, concrete cannot be poured at one time, but it should be divided into layers and sections, and then the construction will be carried out part by part. And before the first concrete solidifies, the second layer of concrete must be poured to ensure its quality.

For concrete mixing and conveying, generally use concrete mixer, drum type or pan mixer and the conveying pump use KMB series, the model of the concrete pump choose deponds on the aggregate size and the conveying distance.
