Description
Technical field
The utility model relates to a kind of novel high slump concrete serviceability tester, belongs to high slump concrete serviceability field tests.
Background technology
A large amount of civil engineering works adopt the high slump concretes such as pump concrete, concrete filled steel tube, self-compacting concrete in recent years.The common feature of these concrete workses is that the concrete mix slump of requirement employing is large, the favorable working performance of concrete mix.
The serviceability of concrete mix comprises that filling capacity, gap are by performance and education resistance energy.Filling capacity (Filling ability), refer to concrete mix in the situation that without vibrating, performance that can even closely knit moulding.Gap refers to that by performance (Passing ability) concrete mix is evenly by the performance of close clearance.Education resistance can (Segregation resisting ability) refer to that in concrete mix, each phase component can keep homodisperse performance.
But the equipment of existing test concrete mix only has slump cone, slump divergence to detect base plate and L-type instrument.Slump cone is only applicable to the slump test of traditional dry concrete mixture, is not suitable for high slump concrete.
The slump divergence detects the filling capacity that base plate can only be tested high slump concrete, can't test gap and pass through performance.In addition, can't guarantee that floor level also will cause the test result deviation larger.
The L-type instrument for detection of the gap of concrete mix by performance and education resistance energy.Testing process is as follows: by L-type instrument horizontal positioned, closed shutter, to deposit concrete in column, finally mention gate, allows concrete mix pass through the reinforcing bar gap and flow into level trough; After mobile stopping, the height H of recording level groove end concrete mix
2.Discharging opening height with reinforcing bar is H
1, gap is PA by performance, gap adopts formula (1) to calculate by performance:
PA=H
2/H
1 （1）
The L-type instrument can only be tested the gap of concrete mix by performance and education resistance energy, can't test filling capacity.And can't regulate diameter and the spacing that is fixed on reinforcing bar in discharging opening, can't meet the needs of the concrete Practical Project of effective simulation.In addition, the L-type instrument faces the problem that can't guarantee the level trough level equally.
Therefore, existing more feasible method of testing is about to the two and is combined with.As " self-compacting concrete direction of design and construction " (the standard CC ES 02-2004 of China Civil Engineering Society) recommends, by L-type instrument and the method that the slump divergence combines, to carry out the serviceability of Comprehensive Assessment self-compacting concrete.
But well-known, fresh concrete can solidify rapidly in dozens of minutes after mix, in the process of test, larger variation has occurred in the performance of concrete mix, therefore by using slump divergence detection base plate and L-type instrument successively to test the filling capacity of high slump concrete, gap by performance and education resistance energy, to cause test result to have very large deviation, and it is too loaded down with trivial details successively to operate two instrumentation program, also wastes test material.
In a word, the serviceability of existing testing apparatus test high slump concrete, not only program is loaded down with trivial details, the waste material, and can't guarantee base plate or level trough level, test interval is larger, therefore the test result deviation increases, and can't meet the requirement of scientific research or practical engineering application.In the urgent need to a kind of novel equipment, so that the serviceability of testing rapidly and accurately the high slump concrete mixture comprises that filling capacity, gap are by performance and education resistance energy simultaneously.
