Experimental and numerical investigation on the dynamic tensile behavior of ultra-high performance cement based composites

Effects of nano-SiO2 particles on the mechanical and microstructural properties of ultra-high performance cementitious composites

“…2. According to former research [21,22], FA was added as a partial replacement of cement at a level of 35% by weight of the total cementitious materials. The proportion was chosen based on a large amount of experiments which can get a homogeneous gradient of fine and coarse particles in the mixture and also considering the workability of the composites.…”

High rate response of ultra-high-performance fiber-reinforced concretes under direct tension

“…On the other hand, there are a few researches reporting the dynamic tensile strength and fracture energy of UHPFRCs by performing spalling test (indirect tensile test) [15][16][17]. Millon et al [15] and Noldgen et al [16] reported that the spalling tensile strength of UHPFRCs was sensitive to the strain rate, whereas their fracture energy was not.…”

Static properties and impact resistance of a green Ultra-High Performance Hybrid Fibre Reinforced Concrete (UHPHFRC): Experiments and modeling

“…For example, Millard [10], Mao [11], Wu [12], and Yi [31] investigated the blastresistance characteristics of UHPFRC. Rong [13,14], Bragov [15], Caverzan [32], Tran [33] and Wang [34] presented the mechanical properties of UHPFRC under high strain rate loading. Nevertheless, all these studies did not consider the cost of utilized fibres, which is significant, since the cost of 1% volume content of fibre applied in UHPFRC is generally higher than that of the matrix [35].…”
