Cement concrete is the most common road material in highway engineering construction. The working performance of the concrete is mainly detected through a slump test of the concrete, so that whether the slump test of the concrete is accurate or not is important.

At present, two commonly adopted concrete slump detection methods are available: one is to press a rammer or a wood ruler on the top of a slump cone manually, and measure the slump of concrete downwards to the highest point of the concrete cone by using a steel plate ruler or a meter ruler to obtain the slump of the concrete; the second is to use slump gauge to measure with reference to manually held graduated scale; the two methods mainly have the following problems:

in the first method, the lower edge of the tamper cannot be accurately contacted with the ruler surface, so that manual reading cannot be accurately performed, and the tamper which is manually held by a user cannot be fixed at the top of the slump meter and is easily affected by operation errors of operators;

the slump scale of the second method is shorter, and when the concrete with large slump is detected, the measuring range limit of the concrete is easy to be approached, and the highest point of the concrete cone cannot be accurately found; the slump scale base is influenced by the working environment and is easy to place unevenly to cause inaccurate reading.
