| dc.description.abstract | The effects of con so I i dati on method and two-course construction on concrete-steel bond in concrete bridge decks are studied as functions of slump, b I eed, and depth of slab. Consolidation was varied by vi bra tor spacing and insertion time. Four top covers were studied: 3/4, I ' and 3 inch mono I ith ic and 3 inch two-course. Bond test specimens were of two types: sha I I ow, with 8 inches of concrete below the reinforcement, and deep, with 24 inches of concrete below the reinforcement. All specimens were modified canti I ever beam type specimens. Concrete densities were obtai ned using core samples. Based on the experimental work, high density internal vibration provides improved bond over low density i nterna r vibration. 3 inch mono I ithic cover provides higher bond strength than 3 inch two-course cover. Increased concrete slump has a negative effect on bond strength for top-cast reinforcement. Deep specimens made with stiff, well conso I i dated concrete can provide the same bond strengths as sha I I ow specimens. | |
