compressive strength analysis assignment
Google the purpose of compressive strength analysis and understand why we do this analysis for the different slags and write something about it from the explanation for the results. Do the same for slump test, Calorimetry and ultrasound test.
What is the purpose of compressive strength test?
compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing. The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.
What is compressive strength of concrete?
Usually, the compressive strength of concrete varies from 2500 psi (17 MPa) to 4000 psi (28 MPa) and higher in residential and commercial structures. Several applications also utilize strengths greater than 10,000 psi (70 MPa).
Look at the reults and tell which slag has the best compressive strength result and why, which could be as a result of addition of magnesium and aluminum, etc
look at the the picture of the reult of the calorimetry and explain for each peak what it represents. the picture result for the calorimetry shows the additions in the slag on the right side of the picture try to find in literature similaar results.
The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure.
from this you can explain that the results of the slump test shows that the slags all have good flowability and workability.
Ultrasonic Pulse Velocity (UPV) testing is used to determine the integrity and quality of structural concrete or stone (up to 6 feet thick) by measuring the speed and attenuation of an ultrasonic wave passing through the element being tested. the setting process differs and then you explain which slag has the best set process and why

Compressive strength results
The result for the compressive strength test is not complete because I need to waity for 28 days to break the sample using the compressive strength machine for sample 7, 8, 9 and reference slag.
Also write about leaching test results from literature.
