“…The ECC effective diffusion coefficient and cracks number are linearly proportional, while on the other hand, it is proportional with the square of the crack width in the reinforced concrete. As the crack width effect is more obvious than the cracks number in chloride penetration, and despite the reduction in the tensile strain capacity and strength, the tests assured the high durability of the ECC materials under increased aging [15].…”

Engineered Cementitious Composite (ECC) is a material with high ductility, tensile strength and self-healing more than the standard concrete. Applications of ECC are beneficial due to its long life cycle, high strength, low cost in the long-term, low maintenance and environmentally friendly nature. Properties and hardened behavior of ECC highlights that ECC has a tight crack width development, which increases its ability to resist long-term effects of hot, frost and humid weather. Additionally, it results low water permeability coefficient and high steel corrosion resistance compared to other common alternative materials. One of the promising areas of application for ECC is in highway structures, especially highway bridges. Highway structures suffer constantly from adverse environmental loads and often require frequent repairing or replacing due to cracks; expansion; water and chlorides effects which cause steel corrosion or the slope between the pavement, slab and the support at the end of a bridge. Detailed review on different properties and characteristics of ECC and the current applications of ECC clearly highlights the motivation to enhance the use of ECC for bridge construction. In addition, ECC can be introduced in jointless bridges by putting an ECC link slab instead of the expandable mechanical joint.

“…Shown in Table 1 are the differences between ECC, FRC, and other common HPFRCC. Despite achieving superiority in terms of tensile strength, ECC has a lower Youngs's modulus (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34) than traditional concrete (40-60 GPa) [3] with the same compressive strength, which indicates a lack of coarse aggregate [4].…”

“…Fluids can flow through the matrix more freely as the particle density rises, but fewer holes are available. Crack development often improves the transport characteristics of concrete, enabling oxygen, water, and chloride ions to rapidly enter and reach the reinforcing steel and expedite the start of steel corrosion in concrete [34]. When the fracture width is less than 100 µm, the crack has minimal impact on the permeability of the concrete.…”

Cementitious composites are one of the world's most consumed infrastructure construction materials because of their abundant resources, mature production process, and strong adaptability. Most of these materials, however, remain brittle. It highlights the need to develop low-cost, high-ductility cementitious materials for structural applications. These issues are the fundamental driving force behind Engineered cementitious composites (ECC) development due to the micromechanical interactions between its constituents and processing techniques. ECC is a high-performance, ultra-ductile fiber-reinforced cementitious composite material designed for high material volume and cost-sensitive applications in the construction sector. However, this material still lacks standardization regarding mix proportion and fiber used as a proper processing technique to balance economy and requirements for strength and durability. This paper aims to review some of the past researchers' design proportions and fiber types used as a reference and guide for future researchers utilizing ECC in their studies. This paper also covers ECC's results and target application in structural engineering.

“…The tensile properties of PVA fiber-reinforced ultra-high toughness cementitious composite (UHTCC) were investigated [17]. The composite shows ultra-high ultimate tensile strain capacity above 4% under uniaxial loading, which is hundreds of times larger than the tensile strain observed in ordinary concrete [18,19]. Zhang [20] developed more cost-effective ECC materials suitable for civil infrastructure applications with low-cost type-C PVA fibers.…”

The physical and mechanical characteristics of seawater coral sand engineered cementitious composites (SCECC) were examined through uniaxial compression, three-point bending, and splitting tensile tests. The mechanical properties were scrutinized under varying fiber volume fraction conditions (V = 0%, 0.575%, 1.150%, 1.725%, and 2.300%). The experimental results indicated that the compressive strength, three-point bending strength, and split tensile strength of SCECC tended to increase with the rise in fiber volume fraction. The strengths attained their maximum values of 45.88, 12.56, and 3.03 MPa when the fiber volume fraction reached 2.300%. In the compression test, the compressive strength of the 7-day specimen can achieve more than 78.50% of that observed in the 28-day specimen. Three-point bending test has revealed that SCECC exhibits favorable strain-hardening and multi-crack cracking characteristics. Fracture patterns of SCECC exhibited variations corresponding to changes in fiber content, as illustrated by their load–deformation curves, the addition of PVA fibers can change the damage mode of cementitious composites from brittle to ductile. The fracture energy of SCECC further attests to its elevated toughness. This is due to the fact that the fibers delay the formation of microcracks and prevent crack expansion, thus significantly increasing the deformability of the material. By verifying its strength, deformability, fracture energy, and other key performance indicators, the feasibility of SCECC in coastal construction projects has been clarified. The successful development of SCECC provides an innovative and high-performance option for the construction of future island projects.
