ABSORPTION AND ABSORPTIVITY OF AGGREGATES AS INDICATORS OF FROST DURABILITY, FINAL INFORMATIONAL REPORT

Eleven aggregate materials were selected, and measurements were made on individual pieces of the absorption, absorptivity, and pore size distribution by mercury intrusion. The Expected Durability Factor (EDF) was calculated from the pore size distribution. Attempts were made to correlate the EDF with various functions of the absorptivity and absorption. An intermediate absorptivity value may be an indicator of poor durability. A function called the Absorptivity Absorption Factor (AAF) was developed. There is a fair relationship between the EDF and the AAF for the less durable materials, and the AAF, which is easy and inexpensive to determine, offers the possibility of being a useful indicator of aggregate durability.
