Review of Cementitious Composites Containing Polyethylene Fibers as Repairing Materials

Abstract

Polyethylene (PE) is an important polymeric material which is widely used in civil engineering. Recently, engineered cementitious composites (ECCs) have adopted PE fibers in structural repairing. ECC with polyethylene fibers (PE-ECC) has excellent tensile properties, ductility, strain-hardening behavior, thermal performance and durability. In this paper, a systematic review of the cementitious composites with PE fibers is summarized to facilitate the application of PE-ECC. The influence of PE fibers on the properties of ECC, such as compressive strength, flexural behavior, shear properties, impact resistance and tensile properties, is presented. Meanwhile, the properties of PE-ECC repaired structures, such as beams, walls and columns, are described. Further, the self-repairing properties of PE-ECC are presented. Finally, some suggestions for future research are provided in order to apply PE-ECC to practical repairing cases. The review exhibits that PE-ECC is of notable significance to the repairing of structures and clarifies its application scope.

Analysis of Abrasion Depth and Rates in Concrete

“…The rate of abrasion of the hydraulic structures depends on the characteristics of the concrete, like the ratio of the water to the composition of the cement (Rahmani, Shamsai, Saghafian, & Peroti, 2012), (E. Horszczaruk, 2004), (Abid, Abdul-Hussein, Ayoob, Ali, & Kadhum, 2020), (Zhou, Xie, Jia, & Wang, 2020), (Somogyi & Pezelj, 2012) grade of the cement, shape and hardness of the aggregates, size, type of fibres, and curing of the surface. Additionally, the environmental factors affecting abrasion are characteristics of the particles responsible for abrasion, the velocity of water, and impact angle.…”

“…The synthetic fibers are presently used in the surface layers of the concrete structures as they possess the capability to augment the resistance to fatigue, impact, temperature shock and corrosion (Abid, Shamkhi, Mahdi, & Daek, 2018), (Grdic, Curcic, Ristic, & Despotovic, 2012), (Ristic, Toplicic-Curcic, & Grdic, 2015), , (Zhou et al, 2020). The cavitation and water-hauled rubble activity are frequently recognized as grating activities.…”

Effects of the Replacement Length of Concrete with ECC on the Cyclic Behavior of Reinforced Concrete Columns

“…ECC shows high tensile ductility based on multiple micro-cracks by incorporating synthetic fibers below 2 vol.%; the micromechanics and steady-state cracking theory are adopted for its material selection and mixture design [3][4][5][6]. Many researchers have tried to utilize this material in structural members and retrofitting [7][8][9][10][11][12][13][14][15].…”

Global Sensitivity Analysis for the Polymeric Microcapsules in Self-Healing Cementitious Composites

“…The microcapsule-contained self-healing cementitious composite involves the polymeric healing agent (repairing the cracks), the catalyst (speeding up the polymerization) and the polymeric shell (encapsulating the healing agent), as exhibited in Figure 1. The healing agents can be cyanoacrylates, Even though microcapsule-contained cementitious composites can achieve self-healing, the elastic properties of the cementitious composite before self-healing happens are influenced because of these soft inclusions based on our previous research [14][15][16][17][18][19][20][21][22][23][24]. The effective elastic properties can be evaluated by micromechanics.…”
