Elastic Modulus

Concrete Elastic Modulus Tester

This device is primarily used to determine the static compression modulus of concrete prism or cylinder specimens. It works by measuring the displacement or strain of the specimen under pressure (or tension) when connected to various testing machines. The elastic modulus is then calculated, allowing for an accurate assessment of the mechanical properties and performance of the material under load.

It offers several advantages, including a lightweight design, compact structure, clear readings, and corrosion resistance. As a mechanical measuring instrument commonly used in concrete material testing, it has been widely applied in scientific research, engineering projects, and universities for the measurement and analysis 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, tighten the nut first (number 13), then connect the right connector (number 12) with two 25mm long positioning sleeves (number 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 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 positioning sleeves as shown in the structural diagram.

2

On the left and right bases (number 17 and 19), install the left and right rulers (number 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 (number 6 and 11) matches the required distance, then tighten the screws (number 5).

4

Mount the two metering tables (number 1 and 8) on the left and right bases respectively, and adjust their positions to ensure proper contact.

5

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

6

When measuring compression deformation, after clamping the test piece (number 9), spin the fixing screw down to the bottom of the lower knife edge, approximately 7mm. After the test, reset it 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 use the hand wheel (number 4) for adjustment.

8

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