Elastic Modulus

Concrete Elastic Modulus Tester

This device is primarily used to determine the static compression modulus of concrete prism or cylinder specimens. It can measure the displacement or strain of a concrete specimen under pressure (or tension) when connected to various testing machines, and then calculate the elastic modulus of the specimen to obtain some mechanical properties and indicators of the specimen under pressure (or tension).

This instrument offers advantages such as lightweight design, compact structure, clear readings, and corrosion resistance. It is a mechanical measuring tool widely used in concrete material testing and has been extensively applied in scientific research, engineering projects, and universities for the measurement, analysis, and control of displacement or strain.

Instructions:

1

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, first tighten the nut (13), then connect the right connector (12) with two 25mm long positioning sleeves (14). Change the position (i.e., 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, loosen the fastening nut, place the right connection on the two 25mm-long positioning sleeves, align them in the middle, and tighten the retaining nut.

If the test piece size is 150×150, place the right connection on the outer edge of the two 25mm-long positioning sleeves, as shown in the structural diagram.

2

On the left and right bases (17) and (19), install the left and right rulers (2) and (7), and tighten the set screws to fix the scale.

3

Adjust the position of the upper knife edge so that the spacing between the upper and lower knife edges (6) and (11) is equal to the required distance, then tighten the screws (5).

4

Mount the two metering tables (1) and (8) on the left and right bases respectively, and touch the position.

5

Hold the left and right connecting plates (16) and (12) with both hands, compress evenly, and if the spring clamping force is insufficient, turn the adjusting nut (21) to adjust the spring pressure.

6

When measuring compression deformation, after clamping the test piece (9), spin the fixing screw down to the bottom of the lower knife edge, approximately 7mm (reset after the test so that the bottom of the lower blade is horizontal).

When measuring tensile deformation, there is no need to rotate the positioning screw down; keep the bottom surface of the lower blade in a horizontal position.

7

To enhance the clamping force of the upper knife edge, you can also adjust it using the hand wheel (4).

8

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