ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard specification for a broad range of supplementary cementitious materials (SCMs). According to ASTM International member Larry Sutter, this performance specification ( WK70466 ) will ease the adoption of new materials used for SCMs as established sources become less available. “For a variety of…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11659 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a new standard for economical testing of concrete strength. The proposed standard, WK82351 , will provide a fast, simple, non-destructive method for testing concrete strength that can be performed almost anywhere. According to ASTM International member Neil Cox this method, which measures the dominant resonant…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11488 ###
