<p><P>PROBLEM TO BE SOLVED: To provide a high strength concrete member for high speed traffic system structure having a performance in which creep itself is remarkably reduced with the improvement of the strength or the toughness. <P>SOLUTION: The high strength concrete member for high speed traffic system structure which has low creep high dimensional accuracy is a hardened body of a composition containing 100 pts.mass cement, 5-50 pts.wt pozzolan fine powder, 50-250 pts.wt aggregate having≤2 mm 85 mass% accumulation particle diameter, 10-35 pts.wt water, and 0.5-4.0 pts.wt water reducing agent (expressed in terms of solid portion). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
