Synergy assessment of hybrid reinforcements in concrete [PDF]
Composites Part B: Engineering, 2018 The present paper is devoted to the assessment of synergy due to the combined use of metallic and synthetic fibres in concrete matrix. Such an evaluation is performed both at first cracking stage by computing fracture toughness, and at post-peak stage by determining two toughness indexes.

Mechanical Properties of Hybrid Fiber Reinforced Rubber Concrete [PDF]
Materials, 2021 Orthogonal experiments were designed for hybrid fiber rubber concrete (HFRC). The mechanical properties of HFRC were tested and compared with ordinary concrete. The effects of basalt fiber volume ratio (VBF), PVA fiber volume ratio (VPF) and rubber volume ratio (VR) on the compressive strength, splitting tensile strength and flexural strength of HFRC ...
