Calculation method of surface adsorption water rate of bone material and manufacturing method of mortar or concrete using the obtained bone material in this calculation method in the centrifugal dewatering test.

摘要

The present invention achieve the characteristic of the divided dough is mixed method, even if the water adsorption rate is greater than the adjusted moisture content. I do centrifugal tested A mortar mixture obtained by the pre-adjusting the water content A to mix the fine aggregate was adjusted with water and cement such a constant value. If the water adsorption rate βo obtained by centrifugation test is greater than the adjusted moisture content A, the aggregate surface in adjusting the water content A of the aggregate prior to centrifugation test estimates that there is an unfilled portion of the water, the following equation (1 ) I seek the surface adsorbed water rate βOH by. Q is the water absorption of the interior of the bone material. βOH = {(βo + A) / 2-Q} / (1 + Q / 100) ... (1). Obtaining a primary water W1 which can exhibit the characteristics of the split Mixing method by substituting the surface-adsorbed water βOH rate in the following equation (3). W1 = (α / 100) × C + (βOH / 100) × S ... (3) [Selection Figure] Figure 2
