ABSTRACT
Compression test and uniaxial tensile test were used to investigate the mechanical properties of the repair materials at the ages of 3, 7, 28 and 90 days.
2.3 Free shrinkage
The free shrinkage of the repair materials was measured according to European standard EN 12617-4. After 24-hour curing covered with plastic paper and under a temperature of 20°C, the specimens were exposed to a temperature of 20°C and RH of 50%.
