Concrete slump detection device and manufacturing operation method thereof

Abstract

The invention provides a concrete slump detection device and a manufacturing operation method thereof. The operation method comprises the following steps that a movable plate and a detection table aretemporarily fastened through L-shaped plug pins, the detection table is adjusted to be in a horizontal state, the inner side of a test barrel is oiled and placed on the movable plate, and the test barrel is filled with mixed concrete; in the filling process, the vibrator on the test barrel is started, vibration is conducted while filling is conducted till the test barrel is full, concrete at theopening of the test barrel is flattened, the test barrel is lifted till the bottom of the test barrel is completely separated from the top end of the concrete to be detected, and the slump of the concrete to be detected is obtained through the scale marks on the stand column. The device is simple, synchronous detection can be realized, and the test efficiency is high; and errors are small, and waste materials are easy to collect.

Description

technical field [0001] The invention relates to the field of concrete detection, in particular to a concrete slump detection device and a manufacturing operation method. Background technique [0002] Concrete slump will be affected by various conditions such as the structural section of the building, steel bar content, transportation distance, pouring method, transportation mode, vibration capacity and climate, so quantitative indicators are needed to measure the degree of concrete slump. In order to judge whether the subsequent construction work can be carried out normally, the concrete slump must be tested during the concrete construction process. [0003] Slump is the measurement method and index of concrete workability. In construction sites and laboratories, slump tests are usually used to measure the fluidity of the mixture, and to evaluate its cohesion and water retention with intuitive experience. , and then get the slump of concrete. The existing slump test method...

Problems solved by technology

The existing slump test method mainly adopts the single bucket test. During the test process, the method of vibrating the concrete with a tamping rod is generally used, and the test needs to be repeated many times to reduce the error of the test data. However, during the test process, at least there will be The following problems: the verticality of the slump test bucket cannot be guaranteed during the lifting process, and the lifting operation is completely controlled by personnel. Different groups of tests are likely to cause large experimental errors, and it will affect the personnel's ability to move into the bucket during the concrete vibration process. Add concrete, thereby delaying the test process and reducing the test efficiency

[0004] In summary, the existing concrete slump test method will cause large test errors due to artificial factors, and the stability and accuracy of the slump test need to be improved
