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ASTM C227 – Standard Test Method for Potential Alkali Reactivity of Cement-Aggregate Combinations (Mortar-Bar Method) (Withdrawn 2018) Description: Significance and Use Data correlating the results of tests performed using this test method with performance of cement-aggregate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. …
ASTM C210 – Standard Test Method for Reheat Change of Insulating Firebrick Description: Significance and Use 3.1 Insulating firebrick (IFB) are classified by their bulk density and reheat change (see Classification C155). This test method defines thermal stability by measurement of IFB’s reheat change following 24 h at a test temperature. 3.2 Since this test exposes the entire …
ASTM C209 – Standard Test Methods for Cellulosic Fiber Insulating Board Description: Significance and Use 4.1 The test methods contained in this document are intended for cellulosic fiber insulating board as described in Specification C208. These test methods examine mechanical, physical and thermal properties, properties related to water absorption and water vapor exposure, and flammability related properties. …
ASTM C204 – Standard Test Methods for Fineness of Hydraulic Cement by Air-Permeability Apparatus Description: Abstract This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. …
