New slabs-on-ground crack when tensile stresses from restrained shrinkage exceed the concrete's strength. This type of early-age cracking occurs during the first few days of the slab's life and is ...
Square shapes, for example, resist cracking the best ... Some suggestions for designing concrete mixtures with reduced shrinkage are also included. Cut two lengths of #4 (1/2 inch diameter ...
[Also,] shrinkage cracks in a slab from too much water initially in the mix, or to adding water during placement, can result in spalling (surface chunks coming loose) that require concrete repair." ...
Researchers from Hohai University, Northwestern University, and Politecnico di Milano have introduced a pioneering mesoscale mechanical discrete model, LDPM-MicroF, to simulate the fracture behavior ...
