ABSTRACT:
When obtaining a mixture such as a mortar or a concrete by adding powder such as cement, water and other liquid to granular materials such as sand, granular slug, artificial fine aggregate, and the like, useful data can be obtained from an underwater highest density packed material which is pressure-packed under an underwater condition where the charging surface of the granular material and the liquid surface are substantially in conformity with each other. In other words, the underwater unit volume weight of the granular material under this state can be obtained, and a fluidizable fine granular quantity and an underwater loosening rate are obtained from this weight. A developed area on a flow table of the mixture and other data are obtained and when these data are employed suitably, the regulation condition of the mixture is forecast and planned with a small error to attain proper utilization.
