ASTM Standard Test Method C39: Compressive Strength of

Aug 28, 2018  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
