What must be done to the sample container prior to sampling the concrete?

Sample must be taken by either passing a receptacle completely through the discharge stream, or by completely diverting the discharge stream into a sample container. The receptacle or sample container must be dampened.

What is ASTM C31?

ASTM C31. This practice provides standardized requirements for making, curing, protecting, and transporting concrete test specimens under field conditions.

What is the number of the procedure by ASTM to obtain a concrete sample?

Sampling (per ASTM C 172) is the first step in determining if the concrete placed complies with specifications. The guidelines are to take composite samples of sufficient total volume (1 ft3 minimum) from the ready-mix truck after 10% and before 90% of the load has been discharged.

How many concrete cylinders are in a set?

A set of 2 to 6 cylinders may be made from the same sample of concrete at a minimum for every 150 cubic yards (115 m3) of concrete placed. It is of prime importance that the specimens are made and cured following standard procedures. Any deviation from standard pro- cedures will result in a lower measured strength.

How many tests are there in concrete?

Among the tests mentioned above, the two major tests mainly considered as quality tests are the compression tests and slump tests. If necessary, it is desired to conduct fresh concrete temperature and hardened concrete density determination tests.

Why do we measure slump?

The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch.

What is water cement ratio in concrete?

The water-cement ratio is the weight of the mixing water divided by the weight of the cement. High-quality concrete is produced by lowering the water-cement ratio as much as possible without sacrificing the workability of fresh concrete, allowing it to be properly placed, consolidated, and cured.

What is ASTM c29?

Standard Test Method for Bulk Density (Unit Weight) and Voids in Aggregate. 1.1 This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination.

Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks.

Why does concrete have 28 days?

The 28-day period is an arbitrary specimen age – though chosen for many good reasons – for testing the compressive strength of concrete. Specification writing authorities chose 28 days as the standard specimen age to establish consistency for testing procedures throughout the industry (1).
