Mass fill concrete 中文
Mass concrete is defined by American Concrete Institute Committee 207 as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of cement and attendant volume change to minimize cracking." As interior temperature of mass concrete rises due to the process of cement hydration, the outer concrete may be cooling and contracting. If the temperature differs too much within the structure… WebSound Concrete. When a coating, overlay or repair mortar is applied to unsound concrete, the bond between the two materials may hold but when pressured, unsound concrete will simply detach from the slab. Cracks, microcracks, blisters, scaling, spalling, or delamination are symptoms of unsound concrete that must be removed, then patched, before ...
