ABOUT THE TOPIC

The ASTM specification for ready mixed concrete lists 90 minutes and 90° F as limits for the delivery time and temperature.  Are these important limits or relics of a bygone era?  Can concrete be successfully transported, placed, and finished beyond these limits?  Mr. Khan will discuss changes in materials and technology that affect delivery time and temperature.
