As an experienced concrete mixing plant manufacturer, Zhengzhou Jianxin Machinery devotes itself into search and develop concrete mixing equipment and tries its best to learn about knowledge on concrete. Now I would like to introduce some of common reasons for quality fault of concrete, and look forward to your correction.
 
1. Aggregate grading is not appropriate. More is the dig stone (sized more than 23mm), smaller is the surface area of aggregate and less is the mortar wrapping aggregate, which will cause the segregation and bleeding.
 
2. Over-high fluidity of concrete especially medium and low-level cocnrete will result in poor uniformity.
 
3. Insufficient mixing time will cause the poor uniformity too.
 
4. Non-standard pouring process, over vibration or some external forces may be the reason.
