A first-of-its-kind standard from ASTM International aims to support the introduction of ethanol as a cooking fuel, a step which will help people in developing countries access and use a safer alternative to wood, charcoal, and other traditional fuels. Each year, millions of people get sick or die due to household air pollution from cooking with traditional fuels, according to ASTM member Brady…, ASTM Committee E48 on Bioenergy and Industrial Chemicals and Biomass Next Meeting:, June 29, 2016, Bellevue, Wash., Media Inquiries:, Nathan Osburn, tel +1.610.832.9603; nosburn@astm.org, Technical Contact:, Brady Luceno, POET Clean Cooking, Sioux Falls, S.D., +1.605.965.6702; brady.luceno@poet.com , ASTM Staff Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #10017

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…

After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard. Until it closed in 1970, the Century Cement Company in Rosendale, N.Y. was the last company to manufacture natural cement. Up to that point, Rosendale had been the center of the industry, the source of more than half of all natural cement produced in the U.S.…
