Ferrocement has had a long history since it was first patented in 1856. Its significant benefits as construction material have been proven with numerous theoretical and experimental studies throughout the world for many years. This paper presents a comprehensive review of the studies on mechanical properties of ferrocement as used in precast and composite precast slabs. Additionally, this paper identifies and prioritizes the most advantageous designs for precast and composite precast ferrocement slabs and reviews the improved characteristics of ferrocement in comparison to traditional reinforced concrete concerning first crack load, ductility, capacity, whole-life cost benefits, and versatile application. Flexible options for different types of applications with its thin structural form provided by ferrocement and its contribution to the first crack load and ductility were discussed. The paper concludes by summarizing success-full uses and the advantages of ferrocement composite applications in precast structures.

“…ECC has high tensile strength from 4 to 6 MPa [4] and large strain capacity between 3% and 5% [5] and also exhibits high ductility by optimizing the microstructure of the composite [6]. In addition, ECC has the ability to confine crack width up to an average of less than 60 microns up to failure [7]. Further details on ECC properties and behavior have been reported by other researchers [8][9][10][11].…”

Eight large-scale reinforced self-compacted engineered cementitious composite (R-SC-ECC) beams with different steel reinforcement ratios have been designed, prepared, cast, cured, and tested to failure at the age of 28 days. The experimental results have been compared with theoretical values predicted using EC2, RILEM, and VecTor2 models. Results show that failure modes in flexure and shear of R-SC-ECC beams are comparable to that of normal reinforced concrete beam. Nevertheless, contrary to VecTor2, models of EC2 and RILEM are not suitable for predicting reasonable ultimate moments for the beams, while results using VecTor2 model have successfully predicted the failure modes and load-deflection curves for all R-SC-ECC beams. It has been concluded that R-SC-ECC fall in the category of ductility class medium to high which gives advantages of using R-SC-ECC beams in regions susceptible to seismic activities.

“…In order to characterize its behavior against cyclic loads, a total of 11 specimens were built with the geometry and characteristics shown in Figure a and Table . The columns of specimens to be tested were 1.3 m long with a 0.2 m square cross section (minimum dimensions of a structural element with moderate energy dissipation MDO according to NSR‐10) . The longitudinal reinforcement was four 12 mm round rebars with 150 x 150 mm stirrups 10 mm in diameter.…”

“…However, limited research has been carried out on the cyclic performance of UHPFRC structural members, since the first publications on testing UHPFRC members under cyclic loads date from 2004 . The appealing mechanical performance of UHPFRC has motivated researchers and engineers to evaluate their application in earthquake‐resistant structures …”

Ultra-high performance fiber reinforced concrete (UHPFRC) is a unique class of fiber-reinforced concrete featuring ultra-high compressive strength and ductile tensile strain hardening behavior, accompanied by multiple narrow cracking. Although many studies have confirmed its superior mechanical and damage tolerance properties under monotonic or blast loading, limited research has been carried out on the cyclic performance of UHPFRC structural members. This paper proposes the use of UHPFRC to improve the cyclic performance of structural elements. An experimental program was carried out on a large number of UHPFRC beam-column joint specimens under a cyclic lateral load. After the cyclic loading test, the following results were obtained: (a) hysterical performance, (b) maximum load, (c) maximum displacement, (d) the maximum energy dissipation (measured by hysteresis cycles), (e) stiffness degradation, (f ) the cracking pattern, and (g) the cracking area. The analysis showed that UHPFRC specimens have at least 157% higher energy dissipation than nonfiber conventional reinforced concrete (RC). The initial stiffness of UHPFRC specimens without fibers (NF) was at least 23% higher than the RC specimen. For UHPFRC with fiber, initial stiffness was at least 45% higher than RC specimen.
