摘要： PROBLEM TO BE SOLVED: To suppress an evaluation cost in quantitatively evaluating the fluidity of a cement hydrate such as concrete.
SOLUTION: A flow mass of the cement hydrate is measured in its fresh state to represent a change with time of the flow mass of the cement hydrate by a curve approximate expression (a quadratic approximate expression, for example). The fluidity of cement hydrate in its fresh state is estimated while calculating its water-powder ratio on the basis of the coefficients of terms of this curve approximate expression (second- and first-order terms, for example). This makes it possible to simply and quantitatively evaluate the fluidity of cement hydrate by using, as indices, the coefficients of the terms of the curve approximate expression representing the change with time of the flow mass of the cement hydrate.

摘要： PROBLEM TO BE SOLVED: To provide a compact bearing stress dispersion member for a tension anchorage device which is attached to each end of a prestressing steel (PC steel) of prestressed concrete.
SOLUTION: According to the structure of the bearing stress dispersion member 10, a metallic grid plate 10a formed like a square flat plate has a circular guide insertion hole 10b formed at the center thereof, and 16 ribs 10c protrude from a peripheral area of the metallic grid plate 10a, followed by boring therein eight through holes 10d. In this manner the bearing stress dispersion member 10 has a simple structure and therefore its production is facilitated. Further by virtue of its compact shape, its storage fees and transportation costs are drastically reduced. Furthermore the bearing stress dispersion member 10 is increased in surface area due to formation of the ribs 10c, and therefore its bearing stress dispersion function is increased.
