抄録

For the purpose of contributing to the jointing plan for the apron pavements of Central Japan International Airport, various tests were conducted in regards to concrete mixed with pulverized blast-furnace slag. Relationships between the amount mixture of pulverized blast-furnace slag, and both the mechanical and shrinkage properties were obtained. Further, the resistance of concrete to cracking was reviewed through stress analysis. In addition, we investigated the conditions in which cracking is induced at the joints of concrete slabs at the actual pavement worksites. These results were then verified using stress analysis.<br>From the stress analyses results, it was found that cracking by shrinkage was induced, where joint spacing was equivalent to that of cement without pulverized blast-furnace slag, when using 40% pulverized blast-furnace slag mixed cement. In relation, results from a follow-up survey concerning with induced cracking in actual concrete slabs, demonstrated a consistency with the stress analysis results.
