摘要： PURPOSE: To measure the characteristics of a mixture by obtaining the underwater unit volume weight of a grain in the most dense state by compacting and filling it in water when obtaining such mixture as mortar where liquid and powder are added to the grain. CONSTITUTION: The grain of a target mixture includes river sand, a thin aggregate such as an artificial thin aggregate, and a fibrous material such as metal fiber and further, as mass-shaped bodies, a rough aggregate of ballast and macadam and each kind of aggregate for giving, for example, sound-screening and heat-insulating property. A liquid is obtained by mixing each kind of assistant and additive to representative water. Also, the grain includes a powdery body used for filling or increasing such as a special cement, stone powder, and clay. While the mixtures are most densely filled by compacting and filling operation, the underwater unit volume weight of the grain is obtained. The characteristics of, for example, the workability, breeding, and fluidizing behavior of the mixture can be measured from the weight and the blend design, manufacture, and control of the mixture of, for example, mortar and concrete can be logically executed by judging characteristics when the blend changes.

摘要： PURPOSE:To reduce the breezing water of a kneaded substance comprising hydraulic substance powder such as cement regarding the kneaded substance, and to obtain a product molded form having excellent strength. CONSTITUTION:When water is added to hydraulic substance powder and a kneaded substance is acquired, primary water adjusted so as to form states before and behind a capillary region centering around the capillary region is added and the powder is primarily kneaded so as to reduce a concretion by said powder and residual secondary water is added and the kneaded powder is finishing-kneaded, and said powder is passed through a kneading process, into which an aggregate is mixed, before finishing-kneading after primary kneading. Breezing is diminished sufficiently, and a product having excellent strength is acquired.

摘要： PURPOSE:To rationally and optimally explain characteristics of a mixture using aggregate to perform estimation, management and adjustment by application-processing mixtures with a plurality of samples with ratios of material to be measured to a medium varied and measuring a solution holding ratio of the medium. CONSTITUTION:With media of powder such as cement and fly ash and water and other liquid used, mixtures with a plurality of samples with ratios of material to be measured to a medium varied are prepared in order to measure adsorption liquid of the materials to be measured such as powder and fine aggregate. Centrifugal force is functioned to the sample to remove the liquid, and a liquid holding ratio which changes in a linear gradient manner along a change in a ratio of the material to be measured to the medium is measured. A slope formed according to the gradient line and a change in a ratio of the material to be measured to the medium is calculated as a relative adsorbed liquid ratio of the material in a mixture. By preparing the medium and the material to be measured in absolutely dry conditions, reference data in the medium and the material can be obtained, so that an adhesion and content relation of the liquid to the medium and the material can be optimally obtained.

摘要： PURPOSE:To enable the forecasting of a product with a stable quality, by preparing a closest packed material by compact packing of particulate material under water to determine underwater unit weight by capacity of the particulate material in the closest packed state. CONSTITUTION:In a mixture of powder such as cement, particulate material such as sand and liquid such as water, underwater unit weight by capacity in a closest packed material is determined concerning the particulate material such as sand having a skeletal structure or function. Water requiring fluidity or the like is made clear quantitatively by this measured value and a mixture of concrete and mortar is explained rationally to closely match the actual condition, thereby enabling the forecasting of a product with a stable quality.
