Concrete Lab Testing Service

Concrete is tested to ensure that the material that was specified and bought is the same material delivered to the job site. There are a dozen different test methods for freshly mixed concrete and at least another dozen tests for hardened concrete, not including test methods unique to organizations like the Army Corps of Engineers, the Federal Highway Administration, and state departments of transportation.
 Slump, air content, unit weight and compressive strength tests are the most common tests. 
* Slump is a measure of consistency, or relative ability of the concrete to flow. If the concrete can''t flow because the consistency or slump is too low, there are potential problems with proper consolidation. If the concrete won''t stop flowing because the slump is too high, there are potential problems with mortar loss through the formwork, excessive formwork pressures, finishing delays and segregation. 
* Air content measures the total air content in a sample of fresh concrete, but does not indicate what the final in-place air content will be, because a certain amount of air is lost in transportation, consolidating, placement and finishing. Three field tests are widely specified: the pressure meter and volumetric method are ASTM standards and the Chace Indicator is an AASHTO procedure. 
* Unit weight measures the weight of a known volume of fresh concrete. 
* Compressive strength is tested by pouring cylinders of fresh concrete and measuring the force needed to break the concrete cylinders at proscribed intervals as they harden. According to Building Code Requirements for Reinforced Concrete (ACI 318), as long as no single test is more than 500 psi below the design strength and the average of three consecutive tests equals or exceed the design strength then the concrete is acceptable. If the strength tests don''t meet these criteria, steps must be taken to raise the average.

Flexural Strength is the ability of a beam or slab to resist failure in bending. It is measured by loading un-reinforced 6x6 inch concrete beams with a span three times the depth (usually 18 in.). The flexural strength is expressed as “Modulus of Rupture” (MR) in psi. Flexural MR is about 12 to 20 percent of compressive strength. However, the best correlation for specific materials is obtained by laboratory tests.

The cube test is the test most commonly used for determining . The value of compressive strength can then be used to assess whether the batch that the concrete cube represents meets the required compressive strength. A cube of concrete in cast is cured for the appropriate time and is then compressed between two parallel faces. The stress at failure is taken to be the compressive strength of the concrete.

This test helps in determining the suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed as concrete mix design. It involves studying properties of Aggregate, Cement, water & Admixture (if any) in use to determine the proper Concrete Mix Design.

This is a partially destructive test that is used to co-relate the various other properties of the concrete viz. UPV, electrical resistivity, rebound number etc. It is customary to take cores of 4 inch diameter for compressive strength determination.Concrete core drilling for strength determination is again dependent upon various factors for reliability. The conversion of concrete core (typically 3 or 4 inch diametercore) strength into 150 mm saturated cube strength depends upon :

  • Effect of coring
  • Shape factor
  • Size effect
  • Direction of coring w.r.t. placing of concrete
  • H/d ratio

 

With so many factors contributing to the final 150 mm saturated cube strength, the strength variation may be + / - 10% - 15%. However, it can be used to confirm the results of UPV differing largely in the values & also for co-relation. Hence the UPV & core results should be judiciously used, interpreted & co-related.
