Manufacture and Applicasion of High-Early Strength Latex-Modified Concrete to Resurface and Repair Bridge Decks

조강형 Latex Modified Concrete를 이용한 교량상판면 보수용 Overlay Concrete 제조 및 적용에 관한 연구

Because of occuring easily the crack, debond, lutting on asphalts pavement of bredge decks under traffic's heavy weigt load. We investigated the application of latex modified concrete to resurface and repaire bridge decks for preventing the above problems. Here, Using the ordinary portland cement and high early cement, We rested mix design, workability, compressive strength, adhesive power, drying shrinkage, carbonation, and economic estimation etc. We selected the condition of application to resurface and repaire bridge decks and detected high early cement is superior to ordinary portland cement in results of analyzing the application of the repairing bridge decks and economic estimations.
