As part of a funded research project on increased fly ash utilization in hydraulic cement concrete, NRMCA is conducting a survey to better understand SCM use. SCM can consist of fly ash meeting ASTMC618/AASHTO M295, slag cement meeting C989 and silica fume meeting C1240. This survey only pertains to SCM used in all concrete supplied by a ready mixed concrete producer. It does not cover SCM use in non concrete applications. The data will be kept confidential and only the overall nationwide survey results will be shared with all survey participants and other researchers.
The completed survey should be e-mailed to Karthik Obla at kobla@nrmca.org no later than Thursday, March 15. The survey form can be downloaded here.
