NRMCA Sustainable Concrete Webinar

The National Ready-Mixed Concrete Association is holding a webinar on April 24, at 9:00-10:30 on the role of performance-base concrete specifications play on delivering concrete with sustainable design criteria.  From their announcement:

Prescriptive requirements such as minimum cement content or maximum water to cement ratio are among many common specification requirements that can increase the environmental footprint of concrete. This webinar outlines how concrete performance can be improved while lowering environmental footprint by implementing performance-based specifications.
