ASTM Standard Test Method C39: Compressive Strength

2021-2-2  Significance and Use of ASTM C39. Concrete's compressive strength determines whether the concrete placed in a structure can bear the weight of what's on top of it, or if it will splinter into a million pieces and cause the structure to collapse. It is highly important for engineers to know how strong concrete is, and so construction materials ...

Standard Test Methods for Compressive Strength of

2019-8-8  other soil-cement tests. It is considered that Method A gives a relative measure of strength rather than a rigorous determina-tion of compressive strength. Because of the lesser height to diameter ratio (1.15) of the cylinders, the compressive strength determined by Method A will normally be greater than that for Method B.

COMPRESSIVE STRENGTH TESTING THE CUBE CONFUSION

2019-2-4  ASTM C 109/C109M Standard Test Method for Compressive Strength Testing of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens) ASTM C 109 is the most common test method when specifying or reporting compressive strength of mortar or grout cubes. This test method was originally written and still only applies to testing cement.

PROCEDURE FOR FSEL COMPRESSION TESTING OF

2016-10-21  until failure occurs. The compressive strength will be determined by dividing the maximum load by the cross-sectional area of the sample. ASTM C39 (Ref. 7.1) and ASTM C42 (Ref. 7.2) formed the basis for the development of this procedure. Two concrete test machine s are available for use in FSEL. The main body of this procedure is applicable
