Question

Types of Tests to be Conducted for the Workability of Concrete
What are the tests to be conducted for the workability of concrete?

Answer 1

Tests on hardened concrete:

Compressive strength (cylinder, cube, core)
Tensile strength: Direct tension
Modulus of rupture
Indirect (splitting) Test
Density
Shrinkage
Creep
Modulus of elasticity
Absorption
Permeability Tests on Concrete
Freeze/thaw resistance
Resistance to aggressive chemicals
Resistance to abrasion
Bond to reinforcement
Analysis for cement content and proportions
In situ tests: Schmidt Hammer, Concrete pull-out, break-off, cones etc.
Ultrasonic, nuclear.

Tests on fresh concrete:

Workability Tests (slump test and others)
Bleeding
Air content
Setting time
Segregation resistance
Unit weight
Wet analysis
Temperature
Heat generation

Of these many tests for concrete quality, in practice well over 90% of all routine tests on concrete are concentrated on compression tests and slump tests. It is also desirable to conduct fresh concrete temperature and hardened concrete density determination tests
