[20AL-TAMIMI, A.K., SONEBI, M., “Assessment of self-compacting concrete immersed in acidic solutions”, DOI: 10.1061/(ASCE)0899-1561(2003)15:4(354). Journal of Materials in Civil Engineering, v. 15, n. 4, pp. 354–357, 2003. https://doi.org/10.1061/(ASCE)0899-1561(... ]	LF	Graph	Self-consolidating concrete (SCC) containing 47% LF lost 40% less mass than the standard concrete. The authors argued that the lower cement content in SCC reduced calcium hydroxide production in concrete, which led to a lesser mass loss.
[29WU, L., HU, C., LIU, W.V., “Effects of pozzolans on acid resistance of shotcrete for sewer tunnel rehabilitation”, DOI: 10.1080/21650373.2018.1519645. Journal of Sustainable Cement-Based Materials, v. 8, n. 1, pp. 55–77, 2019. https://doi.org/10.1080/21650373.2018.15... ]	FA, MK, SF	Graph and table	Shotcrete made with MK or SF had the best results for compressive strength, which the authors associated with the permeable voids reduction in the samples. For all concrete mixes, mass loss under pH 1.5 acid ranged between 2.95% and 3.7%; the concrete with 5% of silica fume demonstrated the lesser mass change. The authors identified the optimum replacement for all acid solutions considering compressive strength and mass loss; however, the values differ for each acid concentration. They also identified a lower correlation between mass change and compressive strength.
[31AJAYI, E.O., BABAFEMI, A.J., “Effects of Pulverized Burnt Clay Waste Fineness on the Compressive Strength and Durability Properties of Concrete”, DOI: 10.4186/ej.2018.22.2.83. Engineering Journal, v. 22, n. 2, pp. 83–99, 2018. https://doi.org/10.4186/ej.2018.22.2.83... ]	PBCW	Graph and table	Concrete made with 20% PBCW lost less compressive strength and less mass than the standard concrete (a resistance loss of 23.8% against 46.9% and a mass change of -5.0% against +4.15% in a 5% H₂SO₄ solution before 90 days). The authors argued that replacing cement with PBCW leads to the formation of secondary CSH and CAH, thereby reducing calcium hydroxide (which is susceptible to corrosion) and reducing interconnectivity among concrete pores.
[32MAKUL, N., SOKRAI, P., “Influences of fine waste foundry sand from the automobile engine-part casting process and water-cementitious ratio on the properties of concrete: A new approach to use of a partial cement replacement material”, DOI: 10.1016/j.jobe.2018.09.004. Journal of Building Engineering, v. 20, n. March, pp. 544–558, 2018. https://doi.org/10.1016/j.jobe.2018.09.0... ]	FWFS	Graph	Concrete made with 40% FWFS lost less mass than the standard concrete. After 180 days, that mixture showed the lowest mass loss compared with concrete made with distinct FWFS replacements in the same water-cement ratio (w/c). The paper reported that the best w/c was 0.45, followed by 0.35.
[34O’CONNELL, M., MCNALLY, C., RICHARDSON, M.G., “Performance of concrete incorporating GGBS in aggressive wastewater environments”, DOI: 10.1016/j.conbuildmat.2011.07.036. Construction and Building Materials, v. 27, n. 1, pp. 368–374, 2012. https://doi.org/10.1016/j.conbuildmat.20... ]	GGBS	Graph and table	Concrete made with 70% GGBS lost less mass and less compressive strength than the standard concrete. The paper presented mass change through g/m² and compressive strength through percentage decay following the corrosion process. However, the authors argued that none of the samples adequately addressed distinct durability for being used in wastewater infrastructure.
[22GOYAL, S., KUMAR, M., SIDHU, D.S., et al. “Resistance of mineral admixture concrete to acid attack”, DOI: 10.3151/jact.7.273. Journal of Advanced Concrete Technology, v. 7, n. 2, pp. 273–283, 2009. https://doi.org/10.3151/jact.7.273... ]	SF	Graph	Concrete made with 5% SF lost nearly 5% less compressive strength and 10% less mass than the standard concrete before 48 days in a 1% H₂SO₄ solution, considering the same w/c (0.25). The study showed that mixtures with w/c 0.25 had a lesser compressive strength loss and a higher mass loss than samples made with a higher w/c ratio. The authors argued that the lower w/c ratio leads to a more intense initial deterioration of the concrete surface; however, the inner matrix was unaffected by the acid attack.

Makara Journal of Technology, v. 19, n. 3, pp. 133–140, 2015. https://doi.org/10.7454/mst.v19i3.3045... ]	FA	Graph	Concrete containing 75% FA lost less compressive strength and mass than the standard concrete in all immersion media (e.g., a resistance loss of 17% against 41% and a mass change of -1.3% against -5.2% in a 15% H₂SO₄ solution before four days). They argued that using FA improves the resistance to sulfuric acid corrosion because it reduces the amount of calcium hydroxide, which minimizes the formation of gypsum and ettringite—both expansive byproducts that reduce the durability and compressive strength of concrete.

SCC made with 50% PZ (strength class = 70 MPa) lost less compressive strength than the standard SCC (loss of 31.9% against 35.1% after 84 days). For all strength classes, SCC made with FA or with PZ lost less mass than the standard SCC (while the SCC made with LF had a higher mass loss). The authors identified that change in compressive strength does not properly indicates concrete surface deterioration after exposure to H₂SO₄. They also stated that increasing cement content increases the risk of corrosion, despite improved compressive strength.

Materials (Basel), v. 12, n. 4, 2019. https://doi.org/10.3390/ma12040593... ]	FA	Graph and table	Concrete containing FA, in all percentages, lost less compressive strength and less mass than the standard concrete. The paper reported that concrete made with a w/c ratio of 0.55 showed the highest acid resistance when compared with concrete made with lower w/c and the same FA addition. When comparing only the cement replacement percentage, samples containing 40% fly ash obtained the best durability values. The authors did not discuss the rationale of their results.
