- Synopsis
- In our Kinki chapter, we have been working in research and experiment group respectively under the committee above-mentioned. In research group, we organized present state of demand and supply for aggregates produced in Kinki region. In experiment group a fact that types and fine particles of aggregate will affect drying shrinkage of mortar and a fact that the increase in paste volume should be considered as to effect of fine particles were expressed. Additionally, simple method of presuming input property values of aggregates for composite model was also under examination.
