ASTM C387/C387M-17 PDF Download

ASTM C387/C387M-17 is a standard specification that outlines the requirements for packaged, dry, combined materials used in the production of concrete and high strength mortar. The standard covers various types of concrete mixtures, including high-early strength concrete, normal strength concrete, normal weight concrete, high-strength mortar, and mortars for unit masonry. The specification includes the composition of materials used in these packaged, dry, combined materials, such as aggregates, admixtures, cement, lime, and polymer modifiers.

The standard also specifies the physical requirements for these materials, including compressive strength, density, air content, and water retention. It provides guidelines for sampling and testing the materials, such as using scales to sample concretes and performing slump tests to check for additional water requirements. For mortar testing, the entire package of dry, combined material is used, and mortar mixing equipment with a bowl positioning adapter is required to ensure clearance for the largest aggregate size.

It is important to note that this standard does not cover mortars specifically for unit masonry, as those are covered by a separate specification, namely ASTM C1714/C1714M.
