For concrete works, two basic type of tests are performed,

1. Pre-concrete Mix test

2. Post-concrete mix test

 

Under pre mix we have 

1. Sieve analysis for fine & coarse aggregates

2. Silt test for fine aggregates

3. Impact value for coarse aggregates

4. Flakiness index test for coarse aggregats

5. Water test basically pH (to be used for concrete works)

6. Cement test(initial & final setting time, fineness)

7. Fineness test for Micro-silica (if used)

 

Post mix test includes

1. Slump

2. Temperature

3. Crushing strength tests in 7,14 ,28 days

 

Scales/parameters of these tests have been slightly variable in different regions of the world as per their code acceptance like ASTM,ACI, IS,BS etc.

 

Hope this answer satisfy you.

Thank you.

1) material testing or the pre mix test.

2) mix test or workability test.

3) post mix test  or strength test.

1-test of fresh concrete is slump test measures the concestency of concrete

 

2-test of pre-cast concrete is compression  test to the crushing  in order to measures compressive strenth 7days 14 days 28 days ages

Before casting: Slump test and concrete temprature.

After casting: Compressive Strength Test (7 - 14 - 28 days).

Also, for investigating concrete strength many test can be used like Schmidt Hammer, Ultrasonic Test and Core Test.

There are many many tests on concrete available and what test to be done depend upon the project requirement.
