Thanks to the fast development of superplasticizers, it is now possible to produce a high performance or ultra-high performance concrete with a low w / c ratio and high dosage of superplasticizer. The effect of water to cement ratio and maximum size of aggregates ( D max ) on the fracture mechanical and fatigue properties were investigated through multiple experiments, including compression test, three point bending fracture test and measurements leading to assessment of fatigue behavior via S-N curve. © 2020 The Authors.

Introduction Many civil engineering structures (such as bridges, high-speed roads and colons of wind turbines) could be exposed to phenomena resulting from the application of repeated cyclic loads (see e.g. Hilsdorf & Kesler (1966), Klaiber & Water to cement ( / ) ratio is one of the crucial parameters for the preparation of concrete, which can significantly affect its workability, mechanical property and durability.
