IMPORTANT TESTS OF CONSTRUCTION MATERIAL

Building material is an any material used for construction purpose like for building a structure. Cement, aggregates, steel, bricks, concrete, clay are the most common type of building material used in construction. The choice of these are based on their cost effectiveness and quality of material for building projects.
To check quality of these material, we have to conduct some test on it. Here below the list of those tests are given for particular material.

1. Tests to check cement quality

  • Float test 
  • Shape test
  • Temperature test 
  • Color test
  • Rubbing test
  • Check for lumps
  • Manufacture date check
Above mention tests are field test of cement which we can perform on site.

  • Fineness test
  • Consistency test
  • Initial and final setting time test
  • Soundness test
  • Compressive strength test
  • Specific gravity test
Above mention tests are lab test.

2. Tests to check sand quality
  • Clay test
  • Organic impurities test
  • Salt taste test
  • Earthy matters test
Above mention tests are field tests which we can perform by observation.
  • Silt content test
  • Bulking of sand test
  • Test of grading of sand or sieve analysis
  • Fineness modulus
Above mention tests are lab tests.

3. Tests to check coarse aggregate quality
  • Surface moisture content test
  • Water absorption test
  • Sieve analysis
  • Fineness modulus
  • Aggregate abrasion value test for hardness
  • Aggregate impact value test for toughness
  • Aggregate crushing value test for strength
  • Test for grading of aggregates
  • Soundness test
  • Shape test ( Flaky index and Elongated index)
  • Specific gravity test
  • Angularity number test
  • Bitumen adhesion test
4. Tests to check fresh concrete quality
  • Slump test
  • Flow test
  • Compacting factor test
  • Vee-bee consistometer test
  • Kelly ball test
Above mention tests are commonly used to measure workability of concrete

5. Tests to check quality of hardened concrete
                  There are two type of tests  perform on hardened concrete to check different aspects.

A. Non destructive tests
  • Water permeability test
  • Water absorption test
  • Modulus of elasticity
  • Rebound hammer test
  • Rapid chloride-ion penetration test
  • Ultrasonic pulse velocity test
  • Magnetic rebar locator test
B. Destructive tests
  • Comressive strength test
  • Split tension strength test
  • Flexural strength test

6. Tests to check quality of steel
  • Tensile test
  • Compression test
  • Impact test
  • Torsion test
  • Rebend test
  • Chemical analysis test

  • Water absorption test
  • Crushing strength test
  • Hardness test
  • Shape and size test
  • Color test
  • Soundness test
  • Structure of brick
  • presence of soluble salts


8. Tests to check quality of wood

  • Test of water absorption 
  • Test of swelling in water
  • Test of moisture content
  • Test of specific gravity
  • Bending test
  • Surface hardness test
  • Tensile strength test
  • Compressive strength test
