“…Additionally, by using post-waste materials, such as fly ash ground, limestone powder and granulated blast furnace slag, self-compacting concrete (SCC) has the characteris tics of high-performance, low-energy consumption, high flowability and convenient construction [ 4,5]. It has been reported that the SCC mixed with high volume fly ash (50% or more) can produce an environmentally friendly concrete with high flowabil ity and durability [6]. Therefore, these two engineer ing materials, high-volume fly ash-SCC (HVFA-SCC) and FRP, have attracted wide attention in the structural constructions [7].…”

The combination of fibre-reinforced poly mer (FRP) and high-volume fly ash self-compacting concrete (HVFA-SCC) reinforced is expected to solve the problem of steel corrosion in traditional structures and develop sustainable infrastructures. Bond beha viour has a strong effect on serviceability of FRP reinforced concrete structures. To achieve the accep tance of this novel composite structures in practical construction and design, it is significantly important to investigate the bond behaviour of FRP reinforced HVFA-SCC. In this study, a series of pull-out tests were carried out to investigate the bond behaviour of HVFA-SCC reinforced by FRP bar, which included bond strength, bond-slip response, and failure mode. The investigated experimental variables were

“…Sangeetha and Joanna [ 139 ] observed that the moment capacity in RC beams with a 40% replacement ratio of GGBFS was comparable to that of the control RC beams without GGBFS at 28 days, however, interestingly it was increased by 21% at 56 days. This could be justified by the enhanced durability [ 139 , 140 , 141 ] and corrosion resistance [ 142 , 143 , 144 ] resulted from the fine glassy shape particles of GGBFS, which reduces chloride-ion permeability, and increases the bond between particles [ 145 , 146 , 147 , 148 , 149 ]. Also, Sangeetha and Joanna [ 139 ] reported that the crack width at service loads was found to be in the range of 0.17 to 0.2 mm, which is within the limits specified by IS 456-2000 [ 150 ].…”

“…This could be attributed to the higher fracture energy formed in the cementitious matrix of FA than the conventional OPC. Alghazali and Myers [ 142 ] investigated the shear behavior of large-scale beams with three replacement levels of FA by weight (50%, 60%, and 70%) and two different longitudinal reinforcement ratios

(1.59% and 2.71%). The FA beams exhibited higher shear strength than the CC ones at a lower

of 1.59%, whereas no obvious increase in the ultimate shear capacity was observed at higher

of 2.71% but the diagonal shear crack propagation was delayed between 10 to 24%.…”

“…The simplified shear design methods are listed in Table 1 . For analysis, two sets of beams were collected from the available literature [ 141 , 142 , 166 , 169 , 170 , 171 , 172 , 178 , 179 , 180 , 181 , 182 ]. The first set consisted of 35 RC beams, 28 of whom the OPC was partially replaced with SCM, while in the remaining 7 RC beams the OPC and the NCA were both replaced with SCM and RCA, respectively as can be noticed in Table 2 .…”

“…Similarly, in JSCE-1997 [ 176 ], the (

) effect is not counted. In the literature, a strong relationship between the shear capacity and varying (

) and (

) has been reported [ 141 , 142 , 166 , 169 , 170 , 171 , 172 , 178 , 179 , 180 , 181 , 182 ]. Hence, the exclusion of these variables is expected to result in inconsistent predictions.…”

Green Concrete for a Circular Economy: A Review on Sustainability, Durability, and Structural Properties

A primary concern of conventional Portland cement concrete (PCC) is associated with the massive amount of global cement and natural coarse aggregates (NCA) consumption, which causes depletion of natural resources on the one hand and ecological problems on the other. As a result, the concept of green concrete (GC), by replacing cement with supplementary cementitious materials (SCMs) such as ground granulated blast furnace slag (GGBFS), fly ash (FA), silica fume (SF), and metakaolin (MK), or replacing NCA with recycled coarse aggregates, can play an essential role in addressing the environmental threat of PCC. Currently, there is a growing body of literature that emphasizes the importance of implementing GC in concrete applications. Therefore, this paper has conducted a systematic literature review through the peer-reviewed literature database Scopus. A total of 114 papers were reviewed that cover the following areas: (1) sustainability benefits of GC, (2) mechanical behavior of GC in terms of compressive strength, (3) durability properties of GC under several environmental exposures, (4) structural performance of GC in large-scale reinforced beams under shear and flexure, and (5) analytical investigation that compares the GC shear capacities of previously tested beams with major design codes and proposed models. Based on this review, the reader will be able to select the optimum replacement level of cement with one of the SCMs to achieve a certain concrete strength range that would suit a certain concrete application. Also, the analysis of durability performance revealed that the addition of SCMs is not recommended in concrete exposed to a higher temperature than 400 °C. Moreover, combining GGBFS with FA in a concrete mix was noticed to be superior to PCC in terms of long-term resistance to sulfate attack. The single most striking observation to emerge from the data comparison of the experimentally tested beams with the available concrete shear design equations is that the beams having up to 70% of FA as a replacement to OPC or up to 100% of RCA as a replacement to NCA were conservatively predicted by the equations of Japan Society of Civil Engineers (JSCE-1997), the American Concrete Institute (ACI 318-19), and the Canadian Standards Association (CSA-A23.3-14).
