S/C Concrete Composition for Steel-Concrete Connection of Bridge and Constructing Methods Using Thereof
The present invention relates to a concrete composition for an S/C joint of a bridge and a construction method using the same. The concrete composition comprises: 50 to 1,000 parts by weight of aggregate; 1 to 30 parts by weight of blast furnace slag fine powder; 1 to 20 parts by weight of fly ash; 0.5 to 10 parts by weight of a fluidizing agent; 5 to 20 parts by weight of a shrinkage reducing agent; 5 to 15 parts by weight of a slump reducing agent; 10 to 30 parts by weight of nano-ceramic particles; 5 to 20 parts by weight of silica fume; 2 to 20 parts by weight of fibers; 0.1 to 5 parts by weight of antioxidant; 3 to 20 parts by weight of an adhesion promoter; 0.5 to 10 parts by weight of a stabilizer; 5 to 30 parts by weight of a strain inhibitor; and 0.01 to 10 parts by weight of a high performance water reducing agent, based on 100 parts by weight of cement. According to the present invention, the concrete composition for an S/C joint of a bridge can secure filling properties within the S/C junction cell and slope formability, and control the flow rate for the slump change of the concrete composition.
