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

Figure 13

Compressive strength of creep-loaded specimens (relative to the average unloaded specimens) vs. the creep loading level for two loading ages (1 and 3 months). The error bar represents the maximum and minimum relative strength values (for 3 specimens). The variabilities of 3 accompanying control specimens ranged between +0.04 and −0.06 for a specimen loading level of 65%; +0.04 and −0.03 for a 50% loading level applied at an age of 1 month; and ±0.02 for 50% and 80% loading levels applied at an age of 3 months.
