Composite Slab Crack Widths Considering Shrinkage and Gravity Loading
An experimental study was conducted on steel fibre-reinforced concrete (SFRC) composite slabs to quantify crack width resulting from shrinkage and gravity loading. Ten full scale slab specimens were evaluated with different types of bond between the concrete and deck (e.g., greased, unembossed deck, regular deck) and different amounts of concrete reinforcement (e.g., mesh, steel fibre). Concrete shrinkage was measured and monitored over a period of 74 days, and then slabs were tested under increasing load. Each was continuous over two spans and two line loads were applied on each span. Relationships between crack size/distribution were obtained for each slab for different levels of applied load.
