Jul 01, 2011  Since curing conditions strongly affect concrete’s surface layer, note that the test specimens (71 × 71 × 50 mm 3) were obtained by sawing larger concrete cubes (100 mm edge) after curing so that the concrete’s surface finishing would not be a variable in the test. Thus, the test surface is the cutting surface itself, i.e. an internal ...

Aug 01, 2000  Specimens at the age of 7 and 14 days of initial water curing provided good results. Silica fume (SF) concrete produced the highest compressive strength at the age of 91 days under these curing conditions. This finding suggests that high performance concrete should be cured by water and the minimum curing period ought to be at least 7 days.
