Background
The slump of concrete mainly refers to the plasticizing performance and the pumpability of the concrete and the workability of the concrete, and particularly ensures the normal operation of construction, including the water retention, the fluidity and the cohesiveness of the concrete. The concrete slump is a standard for judging the workability of concrete construction in actual construction, and if the slump is larger, segregation of mixture is easy to cause, and if the slump is too small, difficulty is brought to construction. Slump tests are generally carried out to measure the fluidity of the mixture, visual experience is used for evaluating the cohesiveness and the water retention, and the larger the slump, the better the fluidity. When the slump is more than 220 mm, the slump cannot accurately reflect the fluidity of the concrete, and the average diameter of the expanded concrete, namely the slump expansion, is used as a fluidity index. The slump test method is the same as that for measuring slump except that slump is measured as the slump depth of the concrete and the slump is measured as the flow range of the concrete (i.e. the diameter of the concrete flow area).
The traditional method for measuring slump is as follows: firstly, placing a slump cone on a flat concrete field, then loading concrete mixture into a standard cone slump cone according to a specified method, after filling and leveling, vertically lifting the cone upwards, moving the cone aside, measuring the vertical distance from the top of the cone to the highest point of the slump concrete by using a ruler to obtain the maximum diameter of the flow area of the slump concrete, wherein the diameter is the expansion degree.
