Description

Testing arrangement for concrete Technical Field The invention relates to the technical field of concrete slump detection, in particular to a testing device for concrete. Background When the slump of concrete is detected, the concrete is poured into a slump cylinder, then the concrete in the cylinder is tamped and smoothed, the slump cylinder is pulled up, the concrete is slumped due to the dead weight, then the slump height is measured, and the initial smoothing height position and the slump height difference are calculated. When concrete is tamped in the slump cylinder, the concrete is generally stirred in the slump cylinder, although the inner wall of the slump cylinder is smooth, the slump cylinder still easily drives the concrete in the slump cylinder to move upwards through the inner wall when rising, so that the surface structure of the concrete is influenced, the slump performance is finally influenced, the slump value is influenced, the slump cylinder is easy to carry the concrete upwards in the existing slump test mode, and the problem of influence on slump performance needs to be solved.
