What are the failures exist on equipment of cement plant continuously

Aug 17, 2018 Minimum concrete cover is reduced when the member is cast in plant vs. cast in the field (better quality control). These variations in cover acknowledge the fact that concrete is porous and that greater concrete cover will significantly decrease the rate of steel corrosion and the subsequent concrete degradation

    CUSUM (or cumulative sum control chart) is a sequential analysis statistical technique developed in the 1950s and widely used in the concrete industry. Natural variations exist in the production of concrete due to variation in the raw materials (aggregate grading, moisture content etc), batching accuracy, plant performance, sampling and testing
