Procedure of Concrete Compression

Concrete compression test is done to know the concrete compressive strength. It is one of two well known concrete test. Another one is slump test.

Required things:
You'll need following things for testing concrete compressive strength -

* Ruler
* Paper
* Pen/Pencil
* Calculator
* activity tape
* Safety eyeglasses
* Gloves
* Testing machine, and ofcourse,
* Concrete specimens (Cylinder/Cube)

Procedure of Concrete Compression take a look at
Step1 - Preparation: Check all the items you wish ar prepared. Check concrete compression machine is in operating order.

Step2 - Safety: Wear hand gloves and safety eyeglasses.

Step3 - Taking measure: Take the measurement of concrete specimens (which ar sent to laboratory for testing). Calculate the cross sectional space (unit ought to air mm2) and place down on paper. Do identical for every specimen.

Step4 - begin machine: activate the machine. Place one concrete specimen within the centre of loading zone.

Step5 - Lowering piston: Lower the piston against the highest of concrete specimen by pushing the lever. do not apply load just. simply place the piston on prime of concrete specimen so it's touching that.

Step6 - Applying load: currently the piston is on prime of specimen. it's the time to use load. Pull the lever into holding position. begin the compression take a look at by Pressing the zero button on the display panel.

Step7 - Increasing pressure: By turning pressure increasing valve counter-clockwise, alter the pressure on piston so it matches concrete compression strength price. Apply the load bit by bit while not shock.

Step8 - take a look at is complete: Observe the concrete specimen. once it begins to interrupt stop applying load.

Step9 - recording: Record the last word load on paper displaying on machine's monitor.

Step10 - Clean the machine: once the piston is back to its position, clean the creaked concrete from the machine.

Step11 - Turning off machine: Match your record yet again with the result on monitor. The result ought to still air monitor. and so put off the machine.

Step12 - Calculate concrete compressive strength: The result we tend to got from testing machine is that the final load to interrupt the concrete specimen. The load unit is mostly in avoirdupois unit. we've got to convert it in newton (N). Our purpose is, to understand the concrete compressive strength.

We know, compressive strength is up to final load divided by cross sectional space of concrete specimen. we tend to took the concrete specimen's measure before beginning the testing and calculated cross sectional space.

Now we tend to got the last word load. thus we will currently calculate the concrete compressive strength.
Compressive strength = final load (N) / cross sectional space (mm2).
The unit of compressive strength are going to be N/mm2.

Normally three sample of concrete specimens ar tested and average result's taken into thought. If any of the specimen compressive strength result varies by quite 15 August 1945 of average result, that result's rejected.
