METHOD FOR IMPROVING SELF-SUPPORTING PROPERTY OF CONCRETE

摘要

PROBLEM TO BE SOLVED: To make high-strength concrete or high-fluidity concrete usable in a slip form method. SOLUTION: In a method for improving self-supporting property of concrete, concrete 5 is first placed in a placing area provided in a sliding form 1 for slip form through a placing chute 2. Then the placing of the concrete is once interrupted and fibers 4 which is a fluidity depressant is scattered on the placed surface 3 of the concrete 5. When the scattering of the fibers 4 ends, the placing of the concrete 5 is restarted.
