Mechanical and Fracture Parameters of Concretes with Different Water to Cement Ratio in Two Different Conditions of Curing

Popis výsledku v původním jazyce

Concretes with the maximum aggregate size of 8 mm and water to cement ratios 0.50, 0.40 and 0.30 were prepared. Mechanical properties including fracture properties were recorded during the first year of ageing. One set of specimens was stored in water and the others were enveloped by foil and left in the laboratory for 28 days. At the age of 28 days, the specimens were measured by 3D computed tomography (CT). Some microcracks were detected by CT, and their contents were compared with the mechanical properties of the concretes. The results show nearly the same mechanical properties of both the water-cured and the foil-enveloped specimens. Some reasons for this behaviour were discussed. The explanation of this phenomenon can help to understand the influence of self-healing on cracks in high-performance concrete.
