Quasi-static and dynamic compressive mechanical properties of engineered cementitious composite incorporating ground granulated blast furnace slag

The effect of synthetic polyethylene fiber on the strain hardening behavior of engineered cementitious composite (ECC)

“…An experimental study by Chen et al [16], to investigate the effect of ground granulated blast-furnace slag (GGBS) on the quasi-static compressive strength and dynamic load-carrying capacity of engineered cementitious composite ECC is presented. The GGBS was used as partial replacement for the fly ash (FA) in ECC with different levels.…”

Strain Rate Dependent Behavior and Modeling for Compression Response of Hybrid Fiber Reinforced Concrete

“…Wang et al (2008) studied the rate dependent stress-strain behavior of SFRC and proposed a model for stress-strain curve based on Weibull function (Weibull, 1951). A simple constitutive model for the DIF (strength) was obtained for GGBFS based concrete by Chen et al (2013). The models were based on experiments conducted on GGBFS concrete for strain rate range of 10 -5 to 188 s -1…”

Compressive behaviour of engineered cementitious composites (ECC) under high strain rates

“…The tensile properties in terms of first cracking strength, ultimate strength, and strain capacity from three test samples are summarized in Table 4.4. Although the tensile ductility performance of ECC developed in this study is not as satisfactory as that reported by previous authors (Yang et al, 2008;Chen et al, 2013), it still shows significant ductility improvement compared to mortar.…”

“…As a good starting point, the constituent materials and their proportions used in the present study (Table 4.1) were selected based on the information given by previous authors (Yang et al, 2008;Chen et al, 2013) with some adjustments to consider utilising raw materials that were obtained locally. As a control specimen, mortar specimens that had the same mix proportion as ECC with no fibre were also fabricated.…”

“…The test results of ECC and mortar under dynamic compression from Chen et al (2013) and Rong et al (2010), respectively are also included in this section for comparison purposes. The experimental results by these authors are chosen since they adopted similar composite mix design with the ECC used in the present study-particularly due to the absence of coarse aggregates in their mix designs.…”
