1. Experiment No. :3
Experiment Name :Compressive
strength test for brick.
Date of testing :8/1/2012
Reporter name :Yawer Abubakir
Group No. :A21
2. The purpose from the experiment
Finding max. Compressiv strength for the
brick.
Apparatus:
1. General compressive testing machine.
2.water pool.
3. Preparing the samples
Choosing 10 samples randomly and dividing the 10
samples 5 groups each group have 2 bricks.In case
of using hollow bricks, the holes should be filled
with cement mortar or gypsum past.
Experiment method (procedure):
1. Sink the samples in the water pool for 24hrs.
2. Remove the samples from water pool (after
24hrs.)and each sample shall be removed the surface
water wiped off with a damp cloth and calculate the
area of the face which load will apply on.
3. Put each sample horizontally in the compressive
testing machine.
4. Use the compressive testing machine and load the
sample with rate (140kg/cm2/min.)until the sample
crashed and record the applied load.
NOTE: - For filling the holes in hollow bricks, the cement
mortar content (sand,cement) should according to the
specification and the samples should be stored in wet
weather for 24hrs. Until cement mortar dry.
