Abstract

The invention discloses a concrete collapse degree test method and a device thereof. A test instrument for testing the performance of a concrete mixture of which the slump is 50 to 220mm comprises a horizontal rod and a vertical straightedge, wherein the horizontal rod is cylindrical; a level bubble is arranged on a middle part of the horizontal rod; a vertical clamping groove is formed in one end part of the horizontal rod; the clamping groove can slide along the horizontal rod; the straightedge can be clamped in the clamping groove, and is vertical to the horizontal rod; the straightedge can slide freely in the clamping groove. The device is convenient to operate with a single hand, and is convenient to read data.

Description

technical field [0001] The invention relates to the technical field of quality detection of building materials, in particular to a method and an instrument for measuring the performance of concrete mixtures with a slump of 50-220mm, which are suitable for fresh concrete. Background technique [0002] In the actual engineering construction process, the concrete slump is an important index used to judge the workability of concrete construction. Only in the case of a suitable slump can there be better construction performance. In order to enable on-site construction personnel to quickly and accurately test the slump and judge whether the concrete meets its design requirements, a suitable measuring tool is particularly important. Existing measurement methods are relatively extensive and not accurate enough. Contents of the invention [0003] The purpose of the present invention is to provide a concrete slump test method and its device, so as to solve the technical problems th...
