ASTM C29 – Standard Test Method for Bulk Density (“Unit Weight”) and Voids in Aggregate Description: Significance and Use 4.1 This test method is often used to determine bulk density values that are necessary for use for many methods of selecting proportions for concrete mixtures. 4.2 The bulk density also may be used for determining mass/volume relationships …
ASTM C289 – Standard Test Method for Potential Alkali-Silica Reactivity of Aggregates (Chemical Method) (Withdrawn 2016) Description: Scope 1.1 This test method covers chemical determination of the potential reactivity of an aggregate with alkalies in portland-cement concrete as indicated by the amount of reaction during 24 h at 80 ° C between 1 N sodium hydroxide solution …
ASTM C288 – Standard Test Method for Disintegration of Refractories in an Atmosphere of Carbon Monoxide Description: Significance and Use 2.1 This test method is used to determine the relative resistance of various refractories to disintegration caused by exposure to a CO atmosphere. The results obtained by this method can be used to select refractories that …
ASTM C279 – Standard Specification for Chemical-Resistant Masonry Units Description: Abstract This specification covers chemical-resistant masonry units, specifically, solid kiln fired bricks and tiles made from clay, shale, or mixtures thereof, suitable for indoor and outdoor use in masonry construction subjected to chemical environments. The bricks and tiles are considered to be of three types …
ASTM C273 – Standard Test Method for Shear Properties of Sandwich Core Materials Description: Significance and Use 5.1 The core shear properties are fundamental properties that are used in the design of sandwich panels. This test method provides information on the force-deflection behavior of sandwich constructions or cores when loaded in shear parallel to the plane …
ASTM E1461 – Standard Test Method for Water Absorption of Core Materials for Sandwich Constructions Description: Significance and Use 5.1 Absorbed water affects the characteristic properties of sandwich core materials, such as electrical properties (for example, dielectric constant, loss tangent, and electrical resistance) and mechanical properties (for example, strength and modulus). The mass of absorbed water …
ASTM C271 – Standard Test Method for Density of Sandwich Core Materials Description: Significance and Use 5.1 Density is a fundamental physical property that can be used in conjunction with other properties to characterize the sandwich core. Most sandwich core structural properties, such as strength and stiffness, are proportional to the density. 5.2 This test method provides …
ASTM C270 – Standard Specification for Mortar for Unit Masonry Description: Abstract This specification covers mortars for use in the construction of non-reinforced and reinforced unit masonry structures. Four types of mortar are covered in each of two alternative specifications: (1) proportion specifications and (2) property specifications. The property specification applies to mortar mixed to …
ASTM C267 – Standard Test Methods for Chemical Resistance of Mortars, Grouts, and Monolithic Surfacings and Polymer Concretes Description: Significance and Use 4.1 The results obtained by these test methods should serve as a guide in, but not as the sole basis for, selection of a chemical-resistant material for a particular application. No attempt has been …
ASTM C266 – Standard Test Method for Time of Setting of Hydraulic-Cement Paste by Gillmore Needles Description: Significance and Use 5.1 The purpose of this test method is to establish whether a cement complies with a specification limit on Gillmore time of setting. Scope 1.1 This test method covers the determination of the time of setting of …
