Description
Technical field
This utility model relates to construction engineering technical field, specifically a kind of concrete flowability testboard.
Background technology
General, the workability of concrete refers to that concrete mix can keep its constituent uniform, and the phenomenon such as laminated segregation, bleeding does not occur, and is suitable to transport, pours, consolidates the construction operations such as molding, and can obtain uniform quality, the performance of closely knit concrete.Workability is a comprehensive technical performance, including mobility, cohesiveness and three aspects of water-retaining property.The workability connotation comparison of concrete mix is complicated, it is difficult to express rightly with a kind of simple assay method and index comprehensively.Specify according to China working standard GB/T50080 1 " Standard for test methods of properties of ordinary concrete mixture ", measure the mobility of concrete mix by the slump and Wei Bo denseness, and be aided with experience directly perceived to evaluate cohesiveness and the water-retaining property of concrete mix.
The slump for dry concrete mixture (slump is less than 10mm) generally uses V-B consistometer to measure its vigorous denseness of dimension, for liquid concrete mixture (slump is more than 10mm), aggregate size is not more than 40mm, uses the slump and slump divergence method.It is Slumping instrument that concrete slump measures conventional instrument, it is made up of slump cone, funnel, tamper, surveyors' staff, leveling ruler and base plate etc., it is 0～25mm that its slump measures scope, minimum division value is Icm, it is impossible to the mensuration (steel ruler need to be used to coordinate the mensuration of divergence) of degree of being extended.Concrete slump is that cylinder is high and difference in height between concrete examination body peak after collapsing, and divergence is that difference is less than the maximum gauge of 50mm and the arithmetic mean of instantaneous value of minimum diameter.Tradition slump instrument uses surveyors' staff and leveling ruler to carry out the mensuration of the slump, a length of 30cm of leveling ruler, and when carrying out the big chutable concrete slump and divergence measures, leveling ruler too short contact can not carry out the mensuration of the slump less than the peak of concrete examination body.When the slump is more than 220mm, the slump can not accurately reflect the mobility of concrete, by divergence as the liquidity scale, the most conventional slump cone, tamper, steel ruler three coordinate the slump and the divergence measuring big chutable concrete, and operation factors artificial during measurement can produce bigger error.

This utility model compared with prior art produced by provide the benefit that:
This one concrete flowability testboard is a kind of easy to operate, and can precisely test the test device of concrete mix mobility.It is big that it measures range, measures accurately；The mensuration of the slump and divergence can be carried out simultaneously, and the big chutable concrete slump and divergence mensuration requirement can be met, the mensuration of concrete flowability can be carried out easily and accurately.
When carrying out the concrete mix slump with divergence mensuration, horizontal survey scale height is regulated by adjusting nut, peak after making horizontal survey scale lower surface contact concrete mix collapse, the scale value reading vertical survey scale is the slump of concrete mix.
Making the edge of two rider angle point alignment concrete mixs of horizontal ruler, by the data of read level chi, calculate its difference, mobile column, measure concrete maximum gauge and minimum diameter, the arithmetic mean of instantaneous value of two diameters is the divergence of concrete.
This one concrete flowability testboard is reasonable in design, simple in construction, safe and reliable, easy to use, be easily maintained, have good value for applications.
