Abstract
A slump meter capable of accurately measuring the workability of concrete relates to an instrument for detecting the workability of concrete and solves the problem of measuring the workability of concrete. It consists of placing a disc (10) above the electronic balance (5) of the quadrangular prism shell, the top of the disc (10) is connected with a cone-shaped tube (11), and the lower end of the tube is provided with a sliding pin (13), and Have horizontal groove (14) and vertical groove (15) on the plate (10), vertical groove (15) communicates with horizontal groove (14), slide pin (13) can insert vertical groove (15), electronic scale (5) There is a supporting plate (8) on the shell of the electric scale, and an annular container (9) is placed on the supporting plate (8), and a level (3, 4) and a screw (2) for adjusting the level of the base are arranged on the base (1) of the electronic scale (5), Digital display (7) and calculator (6) are arranged in the middle part of electronic balance (5), and handwheel (12) is formed on the cylinder (11). This instrument has the advantages of simple operation, digital display, and can accurately measure the workability of concrete test and construction.
Description
Technical field: [0001] The invention relates to a measuring instrument for fresh concrete, in particular to a concrete slump meter suitable for testing the workability of fresh concrete. Background technique: [0002] In the process of concrete testing and construction, slump cylinders are often used to measure the workability of freshly mixed concrete. This method is cumbersome and time-consuming to operate. Human operating factors affect the accuracy of the measurement data, especially when measuring the slump of super-fluid concrete. When falling, it cannot accurately reflect the workability of concrete. Invention content: [0003] In order to solve the problem of inaccurate data of large slump concrete measured by the slump cylinder, the present invention provides a slump meter that is easy to operate, digitally displayed, and capable of accurately measuring the workability of concrete. The specific technical solution for solving the problem of the present invention i...
