Aug 20, 2021 ASTM C 1084 – STANDARD TEST METHOD FOR PORTLAND-CEMENT CONTENT OF HARDENED HYDRAULIC CONCRETE. The broad approach in C1084 is to use analytical chemical means to measure soluble calcium oxide, silica and insoluble residue. Allowing for the aggregate type and composition, the amount of soluble oxide is attributed to the cement, and used to
