Simple Systematization of a Curing Method for Preventing Temperature Cracking on Box Culvert Wall

Abstract

A curing method for warm keeping is effective as a method for preventing temperature cracking that occurs on concrete box culvert wall. Any temperature cracking did not occur also on the concrete box culvert, newly constructed this time, using a curing method for warm keeping.
Based on this fact, fundamental studies were carried out about curing method for warm keeping by the results of temperature measurement including a case of the past and the results of temperature analysis using 3-D finite element method of the inside of concrete wall.
As a result, critical gradient of descending temperature and environmental temperature rise of inner box culvert need to prevent of the temperature cracking were obtained.
Finally, summarizing these fundamental studies, we carried out simple systematization of a curing method for warm keeping.
