| The present research examined heat insulation performance according to change of various laid construction conditions of double bubble sheet being used as material for heat insulation & curing construction of cold weather concrete, and its results are as follows. First, the change in a laid period of bubble sheet within 4 hours and the change in water content inside bubble sheet overall showed similar temperature history and maturity without a big difference in terms of the temperature history of concrete according to construction factors, but it could be confirmed that when a structure was thin or several bubble sheets are laid, requisites unfavorable for initial curing of concrete can occur if a lagger distance between sheets is generated. In terms of the compressive strength of concrete core specimens, it appeared that the initial compressive strength is declined when conditions unfavorable for concrete curing such as delay of a laid period of bubble sheets, induction of large distance between sheets, increase of water content inside bubble sheets and thinness of a structure of placing concrete, etc. were applied, but it appeared that as its age passes, the difference becomes small. |
