Description

Hydraulic engineering concrete quality detection device

Technical Field

The invention belongs to the technical field of concrete detection, and particularly relates to a concrete quality detection device for hydraulic engineering.

Background

At present, no determination method capable of comprehensively reflecting the workability of concrete mixtures exists. In construction sites and laboratories, slump tests are generally carried out to measure the fluidity of the mixture, and visual experience is used for evaluating the cohesiveness and the water retention, and the slump test method comprises the following steps: the concrete mixture is filled into a standard cone slump cylinder according to a specified method, after the cylinder is filled and scraped, the cylinder is lifted vertically upwards and moved aside. The concrete mixture will slump due to its own weight. Then measuring the size of downward slump, wherein the size is slump, the slump is used as a fluidity index, the larger the slump is, the better the fluidity is, when the slump is more than 220mm, the slump cannot accurately reflect the fluidity of concrete, the average diameter after the concrete is expanded, namely the slump expansion, is used as the fluidity index, and the slump test is carried out while the cohesiveness and the water retention of the concrete mixture are observed so as to comprehensively evaluate the workability of the concrete mixture, and the evaluation method of the cohesiveness comprises the following steps: lightly tapping the side surface of the concrete cone which is already collapsed by using a tamper, wherein if the cone gradually sinks, the cohesiveness is good; if the cone collapses, partially collapses or segregates, this is an indication of lack of cohesiveness, and water retention is assessed by the extent to which dilute cement slurry in the concrete mix precipitates. After the slump cone is lifted, if more dilute cement slurry is separated out from the bottom, the aggregate is exposed due to slurry loss of the concrete mixture of the cone part, and the water retention performance of the concrete mixture is poor. If there is not dilute cement paste or only a small amount of dilute cement paste is separated out from the bottom after the slump cone is mentioned, it is good to show this concrete mixture water retentivity, this kind of detection mode all will adopt the slump cone to cooperate, however need pour into many times when present slump cone pours into cement, and the interval needs beat it at every turn, it does not have great clearance to keep concrete inside, this kind of mode detection speed is slow, it is comparatively inconvenient, and traditional directly take off the slump cone from the top and make it cause the influence to the concrete easily, and take out from the top and use also comparatively inconvenient.
