ASTM C114-18 PDF Download

ASTM C114-18 is a standard that specifies test methods for the chemical analysis of hydraulic cement. The standard includes both reference test methods and alternative test methods. The reference test methods are well-established classical chemical test methods that provide a comprehensive analysis of hydraulic cements and are necessary for referee analysis when the conformity to chemical specifications is in question.

The standard identifies the necessary apparatus and materials for conducting the test methods, which include a balance, weights, glassware, laboratory containers, desiccators, filter paper, crucibles, and a muffle furnace. It also outlines the standard reagents to be used, such as purity agents, water, concentrated acids, and indicator solutions.

The standard describes the sample preparation and general test procedures to be followed, which include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculations. The reporting of the analyses should be done in a specific order, including major components, minor components, and separate determinations.

The reference test methods covered in the standard include the determination of various constituents such as insoluble residue, silicon dioxide, ferric oxide, phosphorus pentoxide, titanium dioxide, zinc oxide, aluminum oxide, calcium oxide, magnesium oxide, sulfur, loss on ignition, sodium and potassium oxides, manganic oxide, chloride, and chloroform-soluble organic substances.

The alternative test methods covered in the standard include the determination of calcium oxide, calcium dioxide, magnesium oxide, loss on ignition, titanium dioxide, phosphorus pentoxide, manganic oxide, and free calcium oxide.
