Problems solved by technology

What are used now are some indirect evaluation methods, mainly the slump method. The slump method indirectly reflects the segregation resistance of reactive concrete through cohesion. The slump method can only evaluate the initial concrete segregation degree and cannot reflect the final degree of segregation

Abstract

The invention discloses a cement concrete segregation degree evaluation device and an evaluation method thereof. The device includes a support part, a test part and a density measurement part; the support part includes a base, a vertical arm, a beam, a lifting device, and a bolt; the test The components include fixing screws, a vibrating device, and a material storage chamber; the density measuring components include a column, a density meter, a slide rail, a fixing device, and a guide rail. The invention can simulate the vibration situation of cement concrete in the process of transportation and vibration, and provide more realistic experimental data. It incorporates a density measuring device, which can accurately measure the density of cement concrete in real time. The test device of the invention is easy to operate, good in economy and high in practical value.

Description

technical field [0001] The invention belongs to the field of civil engineering concrete construction, and relates to a cement concrete segregation degree evaluation device and an evaluation method thereof, which are used for evaluating the cement concrete segregation degree and can provide reliable experimental data. Background technique [0002] Concrete segregation is a phenomenon in which the cohesion between the constituent materials of the concrete mixture is insufficient to resist the sinking of the coarse aggregate, and the components of the concrete mixture are separated from each other, resulting in uneven internal composition and structure. It usually shows that the coarse aggregate and the mortar are separated from each other, for example, the dense particles are deposited at the bottom of the large mixture, or the coarse aggregate is separated from the mixture as a whole. [0003] The reasons for segregation may be pouring, improper vibration, excessive maximum p...
