Abstract

The invention discloses a verification device and method for simulating a concrete slump form by discrete elements, and belongs to the technical field of building material performance detection. The verification device comprises a supporting frame, a pair of Y-direction guide rails arranged on the supporting frame in parallel, a first driving brake assembly arranged on the Y-direction guide rails,an X-direction guide rail of which the two ends are fixedly connected with the first driving brake assembly, a second driving brake assembly arranged on the X-direction guide rail, and a distance measuring instrument arranged below the second driving brake assembly and a control terminal which comprises a control module, a data acquisition and calculation module and a data processing module. According to the verification device and method, by measuring the distance of a surface measuring point after the concrete slump, calculating the three-dimensional coordinate of the measuring point, converting the three-dimensional coordinate of the measuring point into a polar coordinate, fitting the polar coordinate into a longitudinal section diagram of the concrete slump form simulated by discreteelements, the concrete slump form simulated by the discrete elements is verified, and a quantitative evaluation index has the reasonability.

Description

technical field [0001] The invention relates to a verification device and method for simulating concrete slump form with discrete elements, and belongs to the technical field of building material performance detection. Background technique [0002] Concrete is one of the most important engineering construction materials. The working performance of fresh concrete is an important factor affecting the efficiency and quality of construction. Accurate measurement of the properties of concrete mixture is the prerequisite for analyzing and predicting the flow behavior of concrete and construction performance. Concrete slump tests are usually required in the study of concrete performance. Generally speaking, in the slump test, people only use a straightedge to measure the slump value of the concrete in the vertical direction and the expansion value of the concrete in the horizontal direction after the slump. [0003] With the deepening of research, scholars began to study the detai...
