A proposed ASTM International standard will be used to evaluate the tensile performance of fiber-reinforced concrete (FRC) using cylindrical specimens with double-punch loading. ASTM’s concrete and concrete aggregates committee (C09) is developing the proposed standard. According to ASTM International member Shih-ho Chao, Professor of civil engineering at the University of Texas at Arlington, a…, 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 #11051 ###

A proposed ASTM International specification will fill the need for a standard covering the use of colloidal silica, a versatile nanoparticle used in concrete that aids in durability. ASTM’s concrete and concrete aggregates committee ( C09 ) is developing the proposed release (WK60809). “Practical applications for colloidal silica in concrete include everything from walkway pavements to building…, 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 #10922

ASTM International’s concrete and concrete aggregates committee ( C09 ) has developed a test method aimed at improving and standardizing the way that resistance of concrete to electrical current flow helps assess its durability. According to ASTM International member R. Douglas Hooton, saturated specimens of hardened concrete are tested to see how well they resist electrical currents. Concrete’s…

A new ASTM International standard will help manufacturers in the aerospace, power generation, and automotive industries test parts for defects. The organization’s nondestructive testing committee ( E07 ) developed the standard (soon to be published as E3213). Through process compensated resonance testing (PCRT), parts from planes, cars, and more can be tested for defects by vibrating the part…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Kristy Straiton, tel +1.610.832.9640; kstraiton@astm.org Release #10792

A new ASTM International standard aims to provide a nondestructive testing alternative that helps reveal imperfections in pipe joints used for gas and water. Specifically, the standard describes how phased array ultrasonic testing (PAUT) can test electrofusion joints in polyethylene pipe systems in the field, either during installation or in service. “Normally, the integrity of these pipe joints…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Kristy Straiton, tel +1.610.832.9640; kstraiton@astm.org Release #10693

Biannual collaborative events and a new standard are helping companies that make or use nondestructive testing (NDT) equipment with their efforts to evaluate whether those systems have interoperable data that can be shared and analyzed. These efforts ultimately help support safety and performance of products and parts for industries such as aerospace, automotive, energy, rail, and other…, “Connect-a-thon” Events, The nondestructive testing committee (E07) is holding biannual “connect-a-thon” events for those who use “digital imaging and communication in nondestructive evaluation” (DICONDE). These open forums – held in conjunction with the committee’s regular January and June meetings – allow DICONDE software developers to network and learn from each other. “Many NDT system providers have found success…, New Standard, A new standardized practice ( E3147 ) from the committee will be used to help evaluate, verify, and validate whether a system complies with DICONDE interoperability. It applies to radiographic, ultrasonic, and eddy current examination instruments and systems. Ferro notes that the standard aims to help archiving and perform analytics for various types of NDT data coming from many inspection…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Kathleen Chalfin, tel +1.610.832.9717; kchalfin@astm.org Release #10507

A proposed ASTM International guide will help concrete professionals use mortar mixtures to compare the relative performance and compatibility of concrete materials. The guide standardizes procedures used for many years in material-performance investigations, according to ASTM International member Ara Jeknavorian of Jeknavorian Consulting Services. “This diagnostic tool will provide concrete…, 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 #10466

A new ASTM International standard will help manufacturing plants better recycle returned fresh concrete, supporting the growth in sustainable construction practices. The new standard (C1798, Specification for Returned Fresh Concrete for Use in a New Batch of Ready-Mixed Concrete), developed by ASTM’s committee on concrete ( C09 ), covers process, verification, and record-keeping procedures for…, ASTM Committee C09 on Concrete and Concrete Aggregates Next Meeting:, June 11-14, 2017, June Committee Week, Toronto, Ontario, Canada, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Technical Contact:, Rich Szecsy, Texas Aggregates and Concrete Association, Austin, Texas, tel +1.512.451.5100; rich.szecsy@tx-taca.org, ASTM Staff Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #10244
