Background

According to the regulation of 'ready-mixed concrete' GB/T14902-2012, concrete which is produced at a mixing plant (building), is delivered to a using place through a transportation device and is mixed when delivered is ready-mixed concrete. The measures of the working performance of the ready-mixed concrete comprise workability, setting time, bleeding rate, pressure bleeding rate and the like, and the test method comprises a slump method.

In commercial concrete mixing plants, due to the fluctuation of concrete raw materials (quality difference, unstable moisture content of aggregate and grit material and difference in water reducing rate of water reducing agent), the performance of the concrete produced by adopting the same mixing proportion has difference, thereby affecting the quality and quality stability of the concrete. At present, the performance of concrete is mainly judged by indexes such as slump and cohesiveness. Therefore, the detection and control technology of concrete slump and cohesiveness is always concerned by manufacturers of concrete mixing plants. At present, concrete slump and cohesiveness are mainly detected by manually measuring the delivered concrete on site by using a concrete slump cone, and the concrete slump and cohesiveness are detected by visual inspection and manual concrete grabbing and experience in actual operation. The other method is to establish the relation between the current and the active power of the motor of the concrete mixer and the performance of the concrete by monitoring the current and the active power of the motor of the concrete mixer and gradually improve the performance of the concrete by manually adjusting the mix proportion, and the method has the problems of large detection error, incapability of adjusting the mix proportion of the concrete in real time and low efficiency.

The existing observation methods can not meet the delivery quality control requirement of concrete and waste manpower. Not only need set up double plate operator, quality control person on the stirring station, still need the tester cooperation to do the testing simultaneously, the job site still needs to set up the outward inspection person and adjusts the unqualified concrete mixture that dispatches from the factory at any time. However, manual field measurement and detection are time-consuming, labor-consuming and inaccurate, and depend on the skill level of a detector and field conditions to a great extent, and the detection result has the phenomena of large error and capability of manually controlling the result. Because of can't be by accurate control when leaving the factory, the concrete mixture also often appears the performance unstability, needs on-the-spot secondary adjustment or directly is returned the problem.
