Elastic Modulus

Concrete elastic modulus tester

It is mainly used to determine the static compression modulus of concrete prism or cylinder specimens.

The instrument can measure the displacement or strain of the concrete specimen under pressure (or tension) by matching various testing machines, and obtain the elastic modulus of the specimen by calculation, so as to obtain the specimen under pressure (or tension). Some mechanical properties and indicators of the time.

It has the advantages of light weight, compact structure, clear reading and corrosion resistance. It is a mechanical measuring instrument in concrete material testing. It has been widely used in the measurement and analysis and control of displacement or strain of various scientific research, engineering, universities and other units.

First, adjust the distance between the two cutting edges according to the size of the test piece.

If the test piece size is

100×100

When the nut should be tightened first (

13

) tighten and connect the right connector (

12

) with two

25mm

Long positioning sleeve (

14

) Change the position (ie, connect the connecting plate to the inside of the two positioning sleeves), and then tighten the tightening nut.

If the test piece size is

125×125

When loosening the fastening nut, put the right connection on the two

25mm

Align the middle of the sleeve and tighten the retaining nut.

If the test piece size is

150×150

When the side puts the right connection on the two

25mm

The outer edge of the positioning sleeve can be as shown in the structural diagram.

2

On the left and right bases (

17

)

19

), install the left and right rulers (

2

), (

7

), and tighten the set screws to fix the scale.

3

Adjust the position of the upper knife edge to make the upper and lower knife edges (

6

)

11

) the spacing is equal to the required distance and then tighten the screws (

5

) Tighten.

4

And two metering tables (

1

), (

8

) The left and right numbers are mounted on the left and right bases respectively, and the position is touched.

5

Hold the left and right connecting plates with both hands (

16

)

12

) Evenly compressing the position, such as the spring clamping force is not enough, you can turn the adjusting nut (

twenty one

) Adjust the spring pressure.

6

When measuring the compression deformation, the instrument will fix the screw after clamping the test piece (

9

) Spin down to the bottom of the lower knife edge>

7mm

(Reset after the test, so that the bottom of the lower edge is horizontal)

When measuring the tensile deformation, the side does not need to rotate the positioning screw down, and still keep the bottom surface of the lower blade in a horizontal position.

7

In order to enhance the clamping force of the upper knife edge, it can also pass the hand wheel (

4

)Adjustment

8

The compression amount of the test piece in the gauge length range is calculated by taking the average value of the two table values.
