What is a slump test? Why is it done? And how to test the slump?
The water cement ratio of concrete can be ascertained through slump test. Water cement ratio is very important for concrete. It depends on the value of compressive strength of concrete. Standard Water Cement has a ratio of 0.4 to 0.5.(concrete cylinder test procedure)
Below are all the requirements for the Slump Test:
1- Slump Cone.
2- Trolley / pan.
3- Measurement tape / scale.
4- Corney.
5- 16mm dia plane roar.
6- Parallel plate.
ā§- āĻোংāĻা.
Slump test method:
At first, there is no slamp cone, the size of which is 6 inches at the bottom, 4 inches at the top and 12 inches at the top of the angular instrument placed on a flat plate.Slump conr must be clean. And oil should be used on its inner surface. 3 parts of the slump cone should be filled with concrete.(civil engineering study tips)
Now you have to hit the sides of the cone 25 times with a plane rod of 18 mm diameter 25 times. Fill it 3 times in a row with concrete and hit it 25 times with 16 mm rod.
You have to do it with Corney.(cylinder test concrete)
It has to be lifted slowly. When lifting the Slam Cone, you can see that the concrete has gone down. Now the slump cone should be placed next to it. After that the value of the scale or measurement tape can be found from the part on the top of the slump to the top of the slump cone.(work experience for civil engineering students)
