Abstract

The invention discloses a concrete workability and uniformity testing device and method. The concrete workability and uniformity testing device comprises a supporting box, a screen is arranged at the top of the supporting box, a reelable piece is laid on the screen, a workability testing device is placed on the reelable piece, and a water supply tank is arranged on one side of the workability testing device; a uniformity testing device is arranged in the supporting box, the uniformity testing device is located below the workability testing device, and a vibration controller is arranged on the supporting box. According to the method, the workability and uniformity of the concrete are comprehensively represented by using the concrete slump and the concrete mortar density deviation, so that the quality of the on-site construction concrete can be better ensured; meanwhile, the concrete subjected to the concrete slump test is directly used for the concrete mortar density deviation test, so that raw materials are saved, and the detection rate is increased; the device is convenient to use, easy to operate, capable of improving per capita productivity and high in accuracy.

Description

technical field [0001] The invention relates to a concrete testing device and method, in particular to a concrete workability and uniformity testing device and method. Background technique [0002] The concrete foundation of power transmission projects has many points, wide area, and large span. Generally, it stretches for thousands of kilometers and needs to cross various complex natural conditions such as climate and geology. At present, there are no mixing plants available around many construction sites, so it is necessary to It is difficult to ensure the workability and uniformity of concrete when transporting fresh concrete from far away to the construction site. In order to ensure the quality of on-site construction concrete, that is, good fluidity, anti-segregation ability and uniformity, some test devices have been developed, such as slump expansion method, U-shaped instrument, etc. These test methods and devices have their own characteristics. The main characteriza...
