Concrete slabs crack when tensile stresses within the concrete overcome the tensile strength. At early ages, the tensile stresses develop from restraint of the concrete's volume changes or slab bending from temperature and moisture gradient through the concrete. Each transverse and longitudinal saw cut induces a plane of weakness where a crack will initiate and then propagate to the bottom of ...

Inspection of underwater concrete structures is required for maintenance and repair works. Methods, types, and objectives of underwater concrete structure inspection are discussed. The service life of any underwater concrete structure, for example, bridges and wharves, and other marine structures, is based on maintaining the physical condition of both superstructure and substructure. That is ...

Aquiferous trough crack formation threatens the durability of structural slabs on underwater concrete. Through cracks can be the result of restrained deformation. Temperature and shrinkage strains that are restrained, cause stresses in the structural slabs. Stresses from restrained deformation can cause through crack formation. During the hardening process and due to climate influences, the ...
