This video demonstrates ASTM C173, the Standard Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method; it is commonly referred to as the Roll-a-Meter test. The Volumetric Air Test method covers the determination of the air content of freshly mixed concrete. It measures the air contained in the mortar fraction of the concrete; it is not affected by air that may be present inside the porous lightweight aggregate particles.
This comprehensive guide presents information about lightweight concrete to equipment owners, designers, specifiers, and contractors to design and evaluate the potential benefits, using the provisions of the AASHTO LRFD Bridge Design Specifications.
This six-part webinar series includes sessions with industry experts sharing proven methodology which identifies root causes of issues encountered on concrete bridges and provides guidance for optimal solutions and design strategies. Understanding this holistic approach dispels perceived limitations in our ability to repair and preserve concrete bridges. Tools are provided to help owners and practitioners be the best possible stewards of critical transportation infrastructure.
