ASTM C260 – Standard Specification for Air-Entraining Admixtures for Concrete Description: Abstract This specification covers materials proposed for use as air-entraining admixtures to be added to concrete mixtures in the field. The air-entraining admixture shall conform to the requirements such as initial and final time of setting, compressive strength, flexural strength, and length change (maximum …
ASTM C25 – Standard Test Methods for Chemical Analysis of Limestone, Quicklime, and Hydrated Lime Description: Significance and Use 4.1 These test methods provide accurate and reliable analytical procedures to determine the chemical constituents of limestone, quicklime, and hydrated lime (see Note 1). The percentages of specific constituents which determine a material’s quality or fitness for use …
ASTM C24 – Standard Test Method for Pyrometric Cone Equivalent (PCE) of Fireclay and High-Alumina Refractory Materials Description: Significance and Use 5.1 The deformation and end point of a cone corresponds to a certain heat-work condition due to the effects of time, temperature, and atmosphere. 5.2 The precision of this test method is subject to many variables …
ASTM C233 – Standard Test Method for Air-Entraining Admixtures for Concrete Description: Significance and Use 3.1 This test method is used to develop data for comparison with the requirements of Specification C260/C260M. These tests are based on arbitrary stipulations permitting highly standardized testing in the laboratory, and are not intended to simulate actual job conditions. Scope 1.1 This …
ASTM C232 – Standard Test Method for Bleeding of Concrete Description: Significance and Use 4.1 This test method provides procedures to be used for determining the effect of variables of composition, treatment, environment, or other factors in the bleeding of concrete. It is also permitted to be used to determine the conformance of a product or …
ASTM C231 – Standard Test Method for Air Content of Freshly Mixed Concrete by the Pressure Method Description: Significance and Use 3.1 This test method covers the determination of the air content of freshly mixed concrete. The test determines the air content of freshly mixed concrete exclusive of any air that may exist inside voids within …
ASTM C230 – Standard Specification for Flow Table for Use in Tests of Hydraulic Cement Description: Abstract This specification covers requirements for the flow table and accessory apparatus used in making flow tests for consistency or mortars in tests of hydraulic cement. The flow table shall consist of an integrally cast rigid iron frame and …
ASTM C227 – Standard Test Method for Potential Alkali Reactivity of Cement-Aggregate Combinations (Mortar-Bar Method) (Withdrawn 2018) Description: Significance and Use Data correlating the results of tests performed using this test method with performance of cement-aggregate combinations in concrete in service, results of petrographic examination of aggregates (Guide C295), and results of tests for potential reactivity …
ASTM C226 – Standard Specification for Air-Entraining Additions for Use in the Manufacture of Air-Entraining Hydraulic Cement Description: Abstract This specification covers deals with air-entraining additions for use in the manufacture of air-entraining hydraulic cement. The materials used are: cement, aggregates, and reference addition. The grading requirements for fine and coarse aggregates are specified. The …
ASTM C215 – Standard Test Method for Fundamental Transverse, Longitudinal, and Torsional Resonant Frequencies of Concrete Specimens Description: Significance and Use 5.1 This test method is intended primarily for detecting changes in the dynamic modulus of elasticity of laboratory or field test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences. …
