Standard Specification for Returned Fresh Concrete for Use in a New Batch of Ready-Mixed Concrete
Abstract: This specification covers requirements for returned fresh concrete for use in a new batch of ready-mixed concrete, as well as the requirements specified by the purchaser. If the requirements of the purchaser differ from ... -
Standard Test Method for Calibration of Hand-Held Moisture Meters on Gypsum Panels
Abstract: 5.1 This Standard Test Method is intended for use in calibrating hand-held meters to accurately read from approximately 30 % to 90 % ERH. Moisture content is related to the ERH or Aw of a material. 5.2 Hand-held meters ... -
Standard Test Method for Concentration of Pinhole Detections in Moisture Barriers on Metal Jacketing
Abstract: 5.1 Corrosion on the interior surface of metal jacketing can be caused by the formation of a galvanic cell between the dissimilar metals of the pipe and jacket or by crevice or pitting corrosion. 5.2 The application of a ... -
Standard Guide for Thermal Performance Testing of Cryogenic Insulation Systems
Abstract: 5.1 A key aspect in understanding the thermal performance of cryogenic insulation systems is to perform tests under representative and reproducible conditions, simulating the way that the materials are actually put together ... -
Standard Specification for Steel Fiber Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe
Abstract: This specification establishes the requirements for steel fiber reinforced concrete pipe (SFRCP) of internal diameters 12-48 in., to be used in the conveyance of sewage, industrial wastes, and storm water as well as the ... -
Standard Test Method for Determination of Thermal Shock Resistance for Advanced Ceramics by Water Quenching
Abstract: 5.1 The high temperature capabilities of advanced ceramics are a key performance benefit for many demanding engineering applications. In many of those applications, advanced ceramics will have to perform across a broad ... -
Standard Test Method for Measurement of Suspended Sediment Removal Efficiency of Hydrodynamic Stormwater Separators and Underground Settling Devices
Abstract: 5.1 Each device has unique flow patterns and turbulence characteristics. In addition, each device exhibits a wide range of efficiencies as discharge, particle-size distribution, particle density, and flow viscosity (that ... -
Standard Guide for Measurement of the Rheological Properties of Hydraulic Cementious Paste Using a Rotational Rheometer
Abstract: 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 ... -
Standard Test Method for Bleed Stability of Cementitious Post-Tensioning Tendon Grout
Abstract: 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 test. ... -
Standard Practice for Evaluating the Condition of Concrete Plates Using the Impulse-Response Method
Abstract: 5.1 The impulse-response method is used to evaluate the condition of concrete slabs, pavements, bridge decks, walls, or other concrete plate structures. The method is also applicable to plate structures with overlays, such ... -
Standard Practice for High-Shear Mixing of Hydraulic Cement Pastes
Abstract: 5.1 This practice is useful in laboratory research on rheology of hydraulic cement systems as it has been shown to provide a paste with rheological properties similar to those obtained in a concrete from which the aggregate ... -
Standard Guide for Evaluating Temperature Effects to Aerosol Foam Sealant During and After Dispensing
Abstract: 5.1 This guide is not intended to measure the precise temperature range for dispensing and curing product under all the possible substrate and environmental factors, but to provide a basis for benchmarking a foam sealant ... -
Standard Test Method for Installed Precast Concrete Tanks and Accessories by the Negative Air Pressure (Vacuum) Test Prior to Backfill
Abstract: 5.1 This is not a routine test. The values recorded are applicable only to the tank being tested and at the time of testing. This test is intended only to demonstrate the sealing effectiveness of the installed system. ... -
Standard Specification for Compression Testing Machine Requirements for Concrete Masonry Units, Related Units, and Prisms
Abstract: This specification provides minimum design standards for testing machines used to measure the compressive strength of concrete masonry units, related units, and masonry prisms covered under Test Methods C140 and C1314. ... -
Standard Specification for Steel Bars Subject to Restricted End-Quench Hardenability Requirements
Abstract: This specification covers hot-worked alloy and carbon-boron steels designed to attain restricted depth of hardening in the end-quench test. These steel compositions are identified by the suffix letter “RH” added to the ... -
