Experimental Study of the Short-Term Creep Behavior of CFRP Strengthened Mortar under Compressive Loading
Creep in cementitious materials is an important part of the delayed strains. It is a complex phenomenon in which many physical and chemical parameters are involved. In this paper, an experimental program was conducted to clarify the creep performance of CFRP strengthened mortar. The main parameters under study are the age at the time of loading and the drying. Specimens are tested at a sustained load of 30% of the ultimate strength. These investigations show the interest of the reinforcement by CFRP of the prismatic mortar specimens, this one allows a notable improvement of the creep behavior.
