CURING AND TENSILE STRENGTH CHARACTERISTICS OF AGGREGATE-LIME-POZZOLAN

The tensile strength of aggregate-lime-pozzolan was found to be a very good indicator of the resistance of the material to freeze-thaw action. A tensile strength of approximately 68 psi (469 kPa) or greater must be attained for the material to have a reasonable chance to withstand freeze-thaw action as exhibited during the freezing season in Pennsylvania. The rate of development of tensile strength of a particular aggregate-lime-pozzolan mix is primarily a function of curing temperature. The higher the curing temperature is, the greater is the rate of gain in strength for the same amount of heat energy input. At temperatures below 50 F (10 C), no appreciable gain in tensile strength is achieved under field conditions.
