Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

Large concrete structures need to be regularly tested for defects that may compromise their stability. While acoustic tests performed by certified inspectors are usually the inspection method of ...

The library is designed on sustainable principles. The two-storey reading room has a cast in situ concrete structure of cylindrical columns; the heads taper and extend to form four arms which support ...

When project teams debate the relative merits of steel and concrete building frames, design quality is seldom the only criterion. Construction time and cost are usually paramount considerations. The ...
