10 Types Of Tests On Brick | How To Check Quality Of Bricks

Bricks in the construction site are the oldest and man-made product in building construction which mainly made by using clay so we have to perform some important tests on bricks to know the quality of bricks and sufficient for construction or not so in this article we learn about those tests in detail

According to use, different types of bricks are carried out for masonry work like mud bricks, refractory bricks, silica bricks, cement, fire etc so a test on brick is required because it’s man-made and also various types of material used in different types. Now basic question triggers in mind how many types of brick tests, Right?

Objective Brick Water Absorption Test

This test is performed to know the water absorption of brick

A water absorption test is a laboratory test of bricks

Absorption of first-class bricks should not exceed 20% of the weight of dry brick

Apparatus Required for Water absorption test

  • Bricks
  • Ventilated Oven
  • Weighing balance
  • Water

Steps Procedure for water absorption test

Below procedures, step follow for carrying out the absorption test
  1. Take 5 nos of bricks randomly
  2. Make it dry in a ventilated oven at 110°C +- 5°C temperature for a period of 48 hours or more
  3. Note down the weight of bricks separately after cooling
  4. Afternote down weight immersed brick into the water at the normal room temperature for the period of 24 hours
  5. Then take out brick after 24 hours make it dry and Quickly note down weight one by one within 3 minit
  6. Not calculate absorption value by the simple formula
    • The water absorption in % = (weight of water absorbed/weight of brick before the test)*100
    • Absorption % = (W2-W1/W1) * 100

    • Where W1 is dry weight, W2 is the weight after immersion of brick for 24 hours
  7. Now carried out the average value of Absorption % all 5 brick. We take the average value for security/safety

Objective for Compressive Strength Test of Brick

A comprehensive strength test of brick is performed to know the compressive strength of brick

IS code follows to perform Compressive Strength Test is 1077-1992 is available for guidance for Compressive strength of brick test IS code

Its also known as the “crushing test” of brick

Compressive strength test of brick is a laboratory test of bricks

The Minimum required crushing strength of bricks should be near 105kg/cm2

Apparatus Required for Compressive strength (Co)

  • Bricks
  • Compressive testing machine
  • Cement, sand and water for mortar

Step in Compressive Strength of brick test procedure

  1. Take 5 nos of bricks randomly
  2. Put it into the water for 24 hours at normal room temperature
  3. Take it out from the water after 24 hours and remove the water contents naturally after that clean the brick surface water
  4. After drying fill out brick frogs by using a standard mortar ratio of 1:1 (1 part cement and 1 part sand)
  5. Leave it for 24 hours in under moisture environment by using gunny or damp sanks to the setting of mortar
  6. Now time for curing brick for 7 days so that mortar gain their strength and became harden
  7. Take out a brick from the water after 7 days and allow the water to drain and make it dry after dry time for a compressive strength test
  8. Place the brick between the plate of the compressive testing machine flatwise keep in mind that the frog of brick facing upward
  9. The applied load axially at a uniform rate of 14 N/mm2/minit is still a failure of brick
  10. Note the Load (P) at which brick break or fail
    • Compressive/Crushing strength (Co) = [Maximun load at failure(p)/Area of the bed face of brick(A)]
  11. Test all 5 bricks and carried out arithmetic mean value of compressive strength
  12. Classification of bricks carried out with the help of Co (compressive strength)

Classification of bricks according to compressive strength

Class of Bricks

Compressive strength

First-class brick

105 kg/cm2

Second class brick

70 kg/cm2

Third class brick or common brick

35 kg/cm2

Fourth class brick or sun-dried brick

15 to 25 kg/cm2

 

Efflorescence Test for Brick

What is efflorescence in brick? This question irritates you Right? but now no more because you read Civil Experience article where we provide each and every detail so, after this, you don’t have to go any other site to find an answer related to Brick Test.

Efflorescence Test For Brick | Test On Brick
