<p><P>PROBLEM TO BE SOLVED: To provide a method for producing finished concrete, which expresses a fine design on the surface of concrete in such a manner that the phenomena that a coarse aggregate appears on the surface of the concrete and bubbles are left therein are prevented. <P>SOLUTION: When a form 20 is set in the lower face of the concrete 10 to be placed to form a finished surface 40, a coarse aggregate is not sunk to the surface plate face of the form 20 by using lightweight concrete using a lightweight concrete aggregate for structures. Alternatively, a coarse aggregate is not sunk to the surface plate face of the form 20 by placing mortar 50 to the upper face of the form 20 and placing the coarse aggregate-containing concrete 10 to the upper part of the mortar 50. Further, when the form 20 is set in the side face of the concrete 10 to be placed to form the finished face 40, the remaining of bubbles in the concrete 10 is suppressed by using high fluidity concrete. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
