Experimental Study of the Creep Effect on the Mechanical Properties of Concrete

Figure 15

Tensile strength (relative to the average unloaded specimens) vs. the creep loading level and quasi-instantaneous preloading of specimens. The error bar represents the maximum and minimum relative strength values (for no less than 3 specimens). The variabilities of 3 accompanying unloaded specimens with respect to the creep-loaded specimens ranged between +0.14 and −0.16, whereas the variabilities (no fewer than 3 accompanying specimens) correlated with quasi-instantaneous preloading were between +0.2 and −0.3.
