ASTM C185 – Standard Test Method for Air Content of Hydraulic Cement Mortar Description: Significance and Use 5.1 The purpose of this test method is to determine whether or not the hydraulic cement under test meets the air-entraining or non-air-entraining requirements of the applicable hydraulic cement specification for which the test is being made. The air …

ASTM C183 – Standard Practice for Sampling and the Amount of Testing of Hydraulic Cement Description: Significance and Use 4.1 The sampling procedures described are intended for use in the procurement of samples of hydraulic cement after it has been manufactured and is ready to be offered for sale. They are not intended as sampling procedures …

ASTM C182 – Standard Test Method for Thermal Conductivity of Insulating Firebrick Description: Significance and Use 3.1 The thermal conductivity of insulating firebrick (IFB) is a property required for the selection of IFB for a specific thermal performance. Users select brick to provide a specified heat-loss and cold-face temperature without exceeding the temperature limitation of the …

ASTM C1812 – Standard Practice for Design of Journal Bearing Supports to be Used in Fiber Reinforced Concrete Beam Tests Description: Significance and Use 4.1 The presence of friction in the supporting rollers used when testing a fiber-reinforced concrete beam will increase the apparent load resistance of the beam. Roller supports designed in accordance with this …

ASTM C181 – Standard Test Method for Workability Index of Fireclay and High-Alumina Refractory Plastics Description: Significance and Use 3.1 Workability index serves as a measure of the facility with which refractory plastic materials can be rammed, gunned, or vibrated into place. 3.2 Workability index is commonly used to control consistency of plastics during manufacture. It has …

ASTM C179 – Standard Test Method for Drying and Firing Linear Change of Refractory Plastic and Ramming Mix Specimens Description: Significance and Use 3.1 This test method is useful in quantitatively rating or ranking both ramming and refractory plastics by their linear stability after heating. 3.2 This test method is also useful for determining whether a ramming …

ASTM C1773 – Standard Test Method for Monotonic Axial Tensile Behavior of Continuous Fiber-Reinforced Advanced Ceramic Tubular Test Specimens at Ambient Temperature Description: Significance and Use 5.1 This test method provides information on the uniaxial tensile properties and tensile stress-strain response of a ceramic composite tube—tensile strength and strain, fracture strength and strain, proportional limit stress …

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.
