Summary of Test Method 3. Capitol St. If it is large, the efficiency of the washing operation should be checked. It could also be an indication of degrada- tion of the aggregate.

Apparatus and Materials 5. N OTE 1—The use of a mechanical apparatus to perform the washing operation is not precluded, provided the results are consistent with those obtained using manual operations. The use of some mechanical washing equipment with some samples may cause degradation of the sample. Sampling 6. If the same test sample is to be tested for sieve analysis according to Test Method C, comply with the applicable requirements of that test method.

If the same test sample is to be tested according to Test Method C, the minimum mass shall be as described in the applicable sections of that method.

Otherwise, the mass of the test sample, after drying, shall conform with the following: Nominal Maximum Size A 4. Greater than 9. Greater than Minimum Mass, g.

ASTM C117 - 17

Concrete cylinders being made in the field. Significance and Use of ASTM C31 Concrete cylinder samples are made for your lab technician to break in a hydraulic press machine and find the compressive strength of the concrete that is being poured for a specific part of a structure. You will get a representative sample of freshly mixed concrete from the truck or mixer, perform slump, temperature, and air content tests on it, and then make cylinders that will be taken back to the lab. These samples provide quality control for architects and engineers and allow them to determine if they will be able to put that concrete into service for their structure, or if they need to remove what they have poured. While you are out on site making cylinders, you can keep lookout for errors in the mixing and pouring of the concrete; field technicians are expected to report things that go wrong to the site superintendent, project manager, or other point of contact for that job. Steel or plastic molds may be used to make cylinders.
