The following is a summary of activity at the ASTM meeting held in Toronto in June of Committees C09 on Concrete and Aggregates, C01 on Cement and E05 on Fire attended by NRMCA staff.

 

C09.20 Aggregates - Notes were added to ASTM C127 and ASTM C128 (specific gravity and absorption of aggregates) to reference AASHTO method T 354 that determines these properties of aggregates by the volumetric immersion method. This method cannot be included in the ASTM standards. The method does not require bringing aggregates to the SSD condition and the precision seems to be improved.

NRMCA can now verify and publish EPDs for each of these materials, in addition to ready mixed concrete and cement.
