A new ASTM International standard provides a more detailed and complete description of a test protocol that has been used for more than 40 years in code requirements and specifications for fire-retardant-treated wood. This test is now also used in some codes for building products that are not wood. The new standard, ASTM E2768 , Test Method for Extended Duration Surface Burning Characteristics of…

Consumers who are purchasing building materials for homes want to be assured that the materials are mold resistant. A proposed new ASTM standard will allow for a mold-resistance rating to be given to specific materials, depending on how the materials perform to the test method. The proposed new standard, ASTM WK32079 , Test Method for Determination of Mold Growth on Building Products Designed for…

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…
