Concrete slabs-on-ground develop curl when a moisture or temperature gradient exists between the top and bottom surfaces of the slab. As the exposed top surface dries and shrinks relative to the ...
When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...
A solid concrete structure may probably fail if gaps are not properly bridged and protected. When the concrete structure serves as a containment vessel of fluids, leakage must be prevented or reduced ...
