Webconcrete slab will act as a restraint to concrete shrinkage. When the shrinkage in the upper portion of the slab is restrained, and thereby lessened, curling will be reduced. The closer … WebThe results show that the grouped L-shape steel rebar connectors significantly affect the restrained shrinkage of the UHPC overlay by increasing the degree of restraint to the UHPC overlay by 13%-38%. The grouped L-shape steel rebar connectors are proven effective in alleviating warping and delamination in the UHPC-NSC composite slabs.
WebAnother important component of continuous steel slab casting is the taper or mold [40,41,42,43,44]. Breakouts occur 20 times due to poor mold taper. A properly tapered mold accommodates for solidifying liquid steel shrinkage to ensure proper contact and heat transmission between the mold wall and semisolidified steel slab.
