Title:
Concrete Hollow Blocks Testing
Objectives:
To determine the maximum load that can be applied and the
compressive strength of the Concrete Hollow Blocks.
Equipment:
Weighing Scale
Caliper
Steel Tape
Marking Pen
Calibrated compression machine
Materials:
An ordinary Concrete Hollow Blocks sample
Procedure:
Step 1: Before starting the initial compressive strength for the concrete hollow blocks,
measure the physical attributes like the length, width, thickness and structural components
of the sample concrete hollow blocks. Observe an accurate recording of data.
Step 2: For the near to exactness measurements slab calipers highly advisable to measure
the web and face thickness of the concrete hollow blocks sample. Same with the other test
conducted weight of the sample is also a factor to consider. Marking of sample, likewise.
Step 3: The sample is now ready for testing. Set up the sample in the calibrated
compression machine, secure that the sample will be placed in the center of the bearing
plate on the top and bottom contact to arrive in near to perfection results.
Step 4: When the sample is ready to be tested, machine will be operated in downward
movement towards the block and proceeds for the compressive force. When the block starts
to crack, it already reached its limit.
Step 5: Data recording and formal documentation will follow upon this result.
Conclusion: A 340 mm length by 90 mm width by 20 mm face thickness by 25 mm web
thickness concrete hollow block with a corresponding weight of 8.21 Kilograms and Gross
area of 35,100 sq. mm has a maximum load of 207, 573 N and compressive strength of
1060 PSI. This concludes that the sample is of normal weight capacity block.
