ASTM C177 – Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means of the Guarded-Hot-Plate Apparatus Description: Significance and Use 5.1 This test method covers the measurement of heat flux and associated test conditions for flat specimens. The guarded-hot-plate apparatus is generally used to measure steady-state heat flux through materials having …
ASTM C1760 – Standard Test Method for Bulk Electrical Conductivity of Hardened Concrete (Withdrawn 2021) Description: Significance and Use This test method measures the bulk electrical conductivity of concrete, which has a theoretical relationship to the diffusion coefficient of chloride ion, or other ions, in the concrete (1, 2). Experimental data confirm that there is a …
ASTM C1758 – Standard Practice for Fabricating Test Specimens with Self-Consolidating Concrete Description: Significance and Use 4.1 Existing practices and test methods for fabricating fresh concrete test specimens are not suited to SCC. This practice provides requirements and procedures for fabricating test specimens with SCC having a slump flow of 500 mm [20 in.] or greater. …
ASTM C1749 – Standard Guide for Measurement of the Rheological Properties of Hydraulic Cementious Paste Using a Rotational Rheometer Description: Significance and Use 4.1 Rheological properties determined using this guide include plastic viscosity and yield stress as defined by the Bingham model and apparent viscosity. 4.2 Rheological properties provide information about the workability of hydraulic cementitious paste. …
ASTM C1741 – Standard Test Method for Bleed Stability of Cementitious Post-Tensioning Tendon Grout Description: Significance and Use 4.1 This test method is designed to evaluate the bleed stability of a freshly-mixed grout under static pressure. It can be used in both the laboratory to qualify grout materials and in the field as a quality control …
ASTM C173 – Standard Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method Description: Significance and Use 4.1 This test method covers the determination of the air content of freshly mixed concrete. It measures the air contained in the mortar fraction of the concrete, but is not affected by air that may …
ASTM C1728 – Standard Specification for Flexible Aerogel Insulation Description: Abstract This specification covers the classification and performance of flexible aerogel thermal insulation. It indicates the mechanical, chemical, and property requirements of the flexible aerogel insulation, such as its thickness, density, and flexibility. It also lists the performance requirements for Types I, II, and III …
ASTM C1723 – Standard Guide for Examination of Hardened Concrete Using Scanning Electron Microscopy Description: Scope 1.1 This guide provides information for the examination of hardened concrete using scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDX or EDS). Since the 1960s, SEM has been used for the examination of concrete and has proved to …
ASTM C1721 – Standard Guide for Petrographic Examination of Dimension Stone Description: Significance and Use 4.1 Petrographic examinations are made for the following purposes: 4.1.1 Determine the physical and chemical characteristics (mineralogy, texture, and composition) of the stone specimen that may be observed by petrographic methods and that have a bearing on the performance of the material …
ASTM C172 – Standard Practice for Sampling Freshly Mixed Concrete Description: Significance and Use 3.1 This practice is intended to provide standard requirements and procedures for sampling freshly mixed concrete from different containers used in the production or transportation of concrete. The detailed requirements as to materials, mixtures, air content, temperature, number of specimens, slump, interpretation …
