28.10.2021 The study analyzes the anisotropy effect for ceramic masonry based on experimental tests of samples made of 25 12 6.5 cm 3 solid brick elements with compressive strength fb = 44.1 MPa and cement mortar with compressive strength fm = 10.9 MPa. The samples were loaded in a single plane with a joint angle that varied from the horizontal plane.
From the results, it shows that brick with 5% of BS sludge obtained the highest compressive strength and lower total shrinkage compared to other percentages. Nevertheless, all the other properties
For testing bricks for compressive strength from a sample the two bed faces of bricks are ground to provide smooth, even and parallel faces. The bricks are then immersed in water at room temperature for 24 hours. These are then taken out of water and surplus water on the surfaces is wiped off with cotton or a moist cloth.
The paper examines the need to test whole bricks as opposed to half or other portions of the brick. This is a matter of importance because machines with the capacity to test whole bricks with a compressive strength above 65 to 70 MPa are scarce and expensive in Australia where many extruded bricks are above this level in their compressive strength.

7 REFERENCES Two bricks are taken and weighed it by using scale weight Clean water is made sure in the curing tank The bricks is put in the curing tank for 30 minutes. The time is recorded using stopwatch. The brick is taken out after 30 minutes and weighed by using scale weight. The weight is recorded and water absorption is calculated.
12.07.2021 2 Compressive strength: crushing or compressive strength of brick is found out by placing it in compression testing machine. It is pressed till it breaks. Minimum crushing strength of brick is Bricks 35kg/cm 2 and for superior bricks, it may vary from 70 to 140 kg/cm 2 .
01.01.2021 The actual compressive strength of masonry with brick strength of 6 MPa and 1:6 mortar was determined by testing in the laboratory as post prediction tests with an average of three specimen and found as 2.91 MPa. However the predicted strength using the interpretation was calculated as 2.83 which is 2.75% lesser than the actual.
The results are compared with the compressive strength tested on a brickwork specimen. Mechanical properties of the mor tar and the bricks have been assessed to evaluate the compressive strength of the brickwork following EC 6. The results are introduced and discussed.

08.03.2022 As mentioned earlier, the fired brick strength must be at least 2,500 PSI per the ASTM standard. The average compression strength for fired facing brick tested by NBRC is around 14,500 PSI.
compressive strength of bricks. generally, bricks have high compressive strength in the range of 5.5 n / mm 2 to 140 n/mm 2. if the crushing strength of the bricks is less than 3.5 n/mm 2 it must not be used. a field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.
In no case for either brick was the average wet strength significantly different from the dry strength. The indirect tensile strength was 9 47 % and 9 49 % of the dry and wet compressive strengths respectively. Considering the 'within batch' variation, this is a rather remarkable result.
