Thanks for the invite. Sorry, the question is out of my field.

From a practical  perspective good concrete is defined by:

  • quality of aggregates (hardness and type)
  • grading of aggregates and their combination with sand etc (affects water retention)
  • quality and type of cement eg sulfide resistant 

onsite

  • slump an indicator of workability (too dry wont move around bars, too wet wont stand up etc)
  • temporature (in high temperatures may need to add ice to slow the hydration process)

Post placement

  • shrinkage test and
  • strength tests at 7 and 28 days

Hardness testing

  • schmidt hammer

Thanks for invitation. 6 tests for concrete:

  • Slump test before leaving the batching plant and on arrival on site.
  • Compressive strength test.
  • Water Permeability test.
  • Rapid Chloride Ion Penetration Test. 
  • Water Absorption Test. 
  • Initial Surface Absorption Test.

  • On aggregates - Many quality control tests are required to check the suitability of material
  • On Fresh concrete - Slump. temprature
  • Hardened concrete - Concrete compressive strength. If required then permeabiltiy, durabilty tests  -

Normal tests on concrete before casting are

 

Temperature measurement

 

Concrete cone test for concrete strength

 

After the hardening, it follows

 

Test the pressure resistance of the concrete, whether cube or cylinder after 7 days and 28 days

 

These are the normal tests of concrete

 

Solid or soft concrete ?? These rigid concrete tests:

 

Check compressive strength

 

Check bending resistance

 

Concrete density inspection

 

Checking the pulp is one of the tests

 

Check the download site

 

The examination of the waves and the hammer is also made of the metabolic tests

 

And the conditions of success is identical to that of the US, British or Iraqi code regarding what I learned in my country Iraq and thank you for the invitation

 

Soft concrete tests:

 

Examination of the coefficient of measurement

 

Check the precipitation

 

Check the soft concrete weight unit

 

Analysis of soft concrete

 

Test the air content and there are tests to precede the process of preparation of the concrete mix of its materials Cement and fine and rough aggregates and conditions of the appropriate water used or in the case of the use of other additives for concrete

Thank you for the invitation

The most important tests are concrete

Cement testing

Building materials test

Concrete mixer across the abrasive cone

Pressure test on concrete cylindrical specimens

Dynamic oscultation

Heat tolerance test

Moisture tolerance test
