HIGH PERFORMANCE CONCRETE COMPOSITION FOR CONSTRUCTING BRIDGE SLAB INTEGRATED WITH PAVEMENT AND BRIDGE SLAB CONSTRUCTION METHOD USING THE SAME

摘要

A concrete composition for the package integrated bridge slab is provided to omit an additional bridge-deck paving by securing a durability capacity and inhibiting crack using only the concrete composition and to enhance a construction property and profitability. A concrete composition for the package integrated bridge slab is manufactured by combining and designing a ternary binding material consisting of cement, fly ash and a ground granulated blast-furnace slag at a standard design compressive strength of 21~40MPa. The ternary binding material comprises the 100 parts by weight of cement, the 5~20 parts by weight of fly ash and the 20~40 parts by weight of ground granulated blast-furnace slag.
