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 ###

Particle size distribution is an important factor in the manufacture of many products, from cement to perfume. A proposed ASTM International standard ( WK45240 ) will set out a general approach to the particle size distribution measurement of powders, suspensions, or slurries using an appropriate wet or dry methodology by the laser diffraction technique. ASTM’s committee on particle and spray…
