specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 , figure 2 with image 3 To illustrate this embodiment, a concrete viscometer described in this embodiment includes a test bench 1, a long groove 2, a roller 3, a pulley 4, a weight 5, a frame 6, a string 10, two slide rails 7, two Weight travel switch 8 and four slide rail brackets 9, each slide rail 7 is placed on the table top of the test bench 1 through two slide rail brackets 9, and the two slide rails 7 are arranged side by side on the table top of the test bench 1 , the long slot 2 is placed on the table of the test bench 1, and the long slot 2 is set between two slide rails 7, and the frame 6 is a rectangular frame composed of two short sides 6-1 and two long sides 6-2 body, the frame 6 is set on the roller 3, and the two ends of the roller 3 are respectively connected to the middle part of the inner side of a short side 6-1 of the frame 6, and the two ends of the roller 3 are respectively provided with a sli...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 with figure 2 Describe this embodiment. The roller 3 of a concrete viscometer described in this embodiment is composed of a rotating shaft 3-2 and three wheel pieces 3-3. 2, and each wheel piece 3-3 is fixedly integrated with the rotating shaft 3-2. In this embodiment, the thickness of the wheel is 5 mm to 10 mm, and the depth of the wheel immersed in concrete is 1 / 3 to 1 / 2 of the concrete depth. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 Describe this embodiment, the height H between the table top of the test bench 1 of the concrete viscometer described in this embodiment and the ground is 800 mm, and the distance L between each slide rail 7 and the table top of the test bench 1 is 180 mm. Other compositions and connections are the same as those in Embodiment 1 or 2.

[0010] working principle

[0011] Fill the long groove 2 with concrete samples to make the surface of the concrete sample smooth, place the two ends of the roller 3 on the two slide rails 7 respectively, and make the three wheels 3-3 of the roller 3 enter the concrete In the sample, the weight 5 relies on gravity to pull the roller 3 to move horizontally along the slide rail 7, and the concrete produces resistance to the rolling of the wheel 3-3. When the weight 5 passes the weight up travel switch 8 from top to bottom, the timer Start timing, and when the weight 5 passes through ...

Abstract

The invention discloses a concrete viscometer, which relates to a viscometer, in particular to a concrete viscometer. The concrete viscometer aims at solving the problem that a concrete viscometer in prior arts cannot accurately measure the rheological parameter of concrete. According to the invention, all slide rails are laid on the surface of a test bench through two slide rail brackets; a longslot is laid on the surface of the test bench; a framework is sleeved on a roller; two slide rail grooves are respectively arranged at two ends of the roller; a pulley is installed between two slide rails; one end of a string is connected with the middle of a long side of the framework; the other end of the string is connected with a weight via the surface of the pulley; the weight can pull the roller to move on a horizontal plane along the two slide rails through gravity; two weight travel switches are arranged on a vertical plane at one end of the test bench from the upper part to the lowerpart; when the weight longitudinally moves along the vertical plane and passes the weight travel switches, the weight can contact the weight travel switches; and each weight travel switch is connected with a timer. The concrete viscometer is used for measuring the viscosity of concrete.

Description

technical field [0001] The invention relates to a viscometer, in particular to a concrete viscometer. Background technique [0002] The measurement method of rheological parameters of fresh concrete, according to the theory proposed by Bingham, at least two parameters of yield stress and plastic viscosity of fresh concrete should be measured. In order to measure these two parameters, foreign scholars have done Quite a lot of improvement work. The famous scholar G.H.Tattersall and his students improved the structure of the rheometer and designed different forms of stirring paddles. Both Japanese and European peer scholars have done work on improving the rheometer. But so far, the data and relevant curves of the experimental reports of the rheological parameters of concrete by scholars from various countries are far from the relevant curves, and the conclusions of the experimental reports are very inconsistent. The main problems in existing concrete rheological parameter me...
