7 Test To Justify Brick Quality

To know the standard of bricks following seven tests may be performed. In these tests some square measure performed in laboratory and therefore the rest square measure on field.

   1. Compressive strength take a look at
   2. Water Absorption take a look at
    3. Efflorescence take a look at
    4. Hardness take a look at
    5. Size, form and Color take a look at
    6. Soundness take a look at
    7. Structure take a look at


 Brick test,
    

Compressive strength take a look at: This test is completed to grasp the compressive strength of brick. it's additionally referred to as crushing strength of brick. usually five specimens of bricks square measure taken to laboratory for testing and tested one by one. during this take a look at a brick specimen is placed on crushing machine and applied pressure until it breaks. the last word pressure at that brick is crushed is taken into consideration. All 5 brick specimens square measure tested one by one and average result's taken as brick's compressive/crushing strength.

Water Absorption take a look at: during this test bricks square measure weighed in dry condition and allow them to immersed in H2O for twenty-four hours. when twenty four hours of immersion those square measure taken out from water and wipe out with artifact. Then brick is weighed in wet condition. The distinction between weights is that the water absorbed by brick. the share of water absorption is then calculated.

The less water absorbed by brick the bigger its quality. smart quality brick does not absorb quite 2 hundredth water of its own weight.

Efflorescence test: The presence of alkalies in bricks is harmful and that they kind a grey or white layer on brick surface by interesting wetness. to search out out the presence of alkali in bricks this take a look at is performed. during this take a look at a brick is immersed in H2O for twenty-four hours so it's taken out from water and allowed to dry in shade.

If the whitish layer isn't visible on surface it proofs that absence of alkali in brick. If the whitish layer visible concerning 100% of brick surface then the presence of alkali is in acceptable vary. If that's concerning five hundredth of surface then it's moderate. If the alkali's presence is over five hundredth then the brick is severely tormented by alkalies

Hardness take a look at: during this test a scratch is formed on brick surface with a tough issue. If that does not left any impression on brick then that's smart quality brick.

Size, form and color take a look at: during this test arbitrarily collected twenty bricks square measure staked on lengthwise, width wise and height wise so those square measure measured to grasp the variation of sizes as per commonplace. Bricks square measure closely viewed to visualize if its edges square measure sharp and straight and uniform in form. an honest quality brick ought to have bright and uniform color throughout.

Soundness take a look at: during this test 2 bricks square measure command by each hands and smitten with each other. If the bricks offer clear bi metal ringing sound and do not break then those square measure smart quality bricks.

Structure take a look at: during this test a brick is broken or a broken brick is collected and closely determined. If there square measure any flows, cracks or holes gift on it broken face then that won't smart quality brick.
