The highly durable concrete with blast furnace slag cement and expansive additive were utilized in the RC slab construction of Hikohei PC composite girder bridge. In the present research, FEM full scale structural model of Hikohei PC composite girder bridge has been successfully verified regarding early age thermal stress simulation. Simulated thermal stresses and consequent parametric studies have confirmed that thermal cracking risk is insignificant in PC composite girder RC slab with expansive additive when appropriate construction procedures are ensured avoiding extreme ambient conditions. |
