“…This was attributed to the added superplasticiser (SP) having a fineness of 22.10 4 cm 2 /g in the composition of composite mortars. In this context, Monteny et al [43] reported that nano-silica affected the pore microstructure in addition to enhancing capillary suction and penetration depth of acid solution in mortars. Also, Bassuoni and Nehdi [44] added that grinding additions more finely encouraged mass loss up to 50%.…”

“…Table summarizes the results of split tensile strength test of controlled, binary, and quaternary concrete and it can be observed that the strength increases with time due to continued pozzolanic reactions. The study reported that split tensile strength increases with increase in the FA content . Although the study was conducted on binary blend, the similar results are obtained for quaternary blend.…”

“…From the mechanical, durability, and microstructure studies, it is established that concrete so produced with the help of the quaternary binders are more resistive to all weathering actions. The amount of calcium hydroxide, which is vulnerable to chemical attack, is reduced by adding limestone fillers, blast furnace slag, and natural pozzolana, which in turn improves the resistance of concrete in aggressive environment, especially acidic due to sulfuric acid . The slag has a stable and uniform chemical composition compared to FA, SF, and other natural pozzolan and therefore it is very much liked in the cement industry.…”

“…FA and SF in ternary cements provide better compressive strength than binary blends. Extensive literature review suggested that synergy of binary blends (OPC + SF, OPC + FA, or OPC + GGBS) and ternary blends (OPC + GGBS + SF and OPC + FA + SF) has been well investigated and there is a need to explore synergy between quaternary blends . The main objective of this research is to investigate the effects of different combinations of quaternary mix in cement concrete properties at both macro and micro level.…”

Industrial byproducts such as fly ash (FA), silica fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and lime powder (LP), popularly known as supplementary cementitious materials (SCMs), have been extensively used in the manufacturing of cement and cement products in binary and ternary modes. In the present study, attempt has been made to develop a new sustainable green quaternary binder by partially replacing ordinary Portland cement (OPC) with different percentages of SCMs and find the optimum mix that can provide the best results in terms of mechanical as well as durability properties. The motivation is to reduce our dependency on OPC to reduce carbon foot print and utilizing these industrial byproducts for the sustainable development. Different compositions of quaternary binders were prepared and their physical, mechanical, and durability properties were studied and compared with the OPC and binary cement product pozzolanic Portland cement (PPC). The mechanical properties of concrete prepared with these OPC, PPC, and quaternary binders were also studied and it is established that the concrete mixtures prepared with quaternary binders provided better results and proved to be more economical. It is concluded that quaternary binders (a) OPC70% + FA15% + SF7.5% + GGBS7.5%, (b) OPC70% + FA15% + SF7.5% + MK7.5%, (c) 50%OPC + 30%FA + 10%SF + 10%GGBS, and (d) 50%OPC + 30%FA + 10%SF + 10%MK have produced relatively better strength, improved durability, and resistance to sulfate attack. These findings were also supported with the microstructural studies of hardened concrete of M20 grade using scanning electron microscope (SEM) and X‐ray diffraction (XRD).

“…Especially subjected to sulfuric acid, which is a very strong acid and originates from industrial processes, urban activity, mine wastewater or acid rain, the durability of concrete can significantly decline due to corrosion of embedded reinforcement and degradation of the concrete [1] . The deterioration rate of concrete due to acidification depends on the thickness and permeability of the concrete cover, type of binder, curing, density, water cement ratio, and environmental effects such as the concentration of the acid and the type, temperature, relative humidity, etc [2][3][4][5][6] .…”

According to the results of accelerated tests of acidification corrosion depth and compressive strength of concretes subjected to sulfuric acid environments, the acidification depth laws of concretes were predicted based on the grey system theory. Thus, the remaining compressive strength was calculated when the acidification depth reached the protection layer thickness of concrete structures, which indicates that the limit state of durability failure can be defined based on strength degradation, and the calculation process was illustrated by an example. The calculated results show that the remaining compressive strength values in the durability failure limit state for the concrete structures exposed to pH=2 and 3 sulfuric acid water environments and wet-dry cyclic sulfuric acid environment with pH=2 are 74%, 72%, and 80% of initial strength, respectively. The method provides references for the durability evaluation of concrete structure design under the acidic environments.
