“…According to the results of the current study, the results reported by Hendi et al [123], Bassuoni and Nehdi [124], Chang et al [125], and De Belie et al [126] found that there is no direct correlation between compressive strength changes and weight changes after exposure to the sulfuric acid solution [123][124][125][126].…”

“…Due to the reduction of concrete porosity, any slight formation of gypsum and ettringite leads to internal stresses and premature cracking. In the next step, sulfuric acid attacks C-S-H easier and faster due to the reduction of the availability of Ca(OH) 2 , which causes the instability of the cement paste and loss of strength [123].…”

“…Undoubtedly, the pore volume is one of the most efective parameters in improving the resistance of concrete against sulfuric acid attacks. Because the higher pore volume provides more accessible spaces for the formation of gypsum and ettringite, and as a result, internal stresses and intense damage are prevented [123].…”

By considering the adverse environmental impacts of the cement manufacturing process, there have been many efforts for cement replacement by supplementary cementitious materials (SCMs), which can enhance the produced concrete performance while reducing cement consumption. This study evaluated the effects of various proportions of silica fume (SF), waste glass powder (WGP), and ground granulated blast furnace slag (GGBFS) on the mechanical and durability properties of concrete. The properties evaluated in this study include compressive, tensile, and flexural strength, magnesium sulfate and sulfuric acid attack, surface resistivity, rapid chloride penetrability test (RCPT), water absorption, depth of penetration of water, and microstructure analysis by scanning electron microscopy (SEM). The results of compressive, tensile, and flexural strength, chloride ion penetrability, and water absorption tests showed that adding 5% of SF to mixtures containing 10% WGP or 10% GGBFS improved concrete performance significantly due to packing density and synergistic effect; however, adding 5% of SF to concrete mixtures decreased the resistance against the magnesium sulfate and sulfuric acid attack. The binary mixture of 15% of WGP showed appropriate performance against the magnesium sulfate and sulfuric acid attack, which may be due to the sacrificial nature of WGP. In addition, the binary mixtures of 15% of WGP and 15% of GGBFS reduced the depth of penetration of water by 45%. Microstructure analysis by SEM showed that the presence of SF, along with WGP and GGBFS, improves the packing density. Finally, adding 5% of SF is suggested to improve the properties of concrete mixtures containing WGP and GGBFS.

“…However, the required data may be complex or insufficient [ 11 ] for estimating the compressive strength of concretes [ 12 , 13 ]. These studies involved issues related to high performance [ 1 , 14 , 15 , 16 , 17 , 18 , 19 ], self-compacting concrete [ 20 , 21 , 22 , 23 ], and lightweight concretes [ 24 , 25 , 26 ], sulphate resistance in concrete [ 27 , 28 ], cyclic behavior of concretes [ 29 ], recycled aggregate [ 1 , 30 , 31 ] and waste material [ 27 , 32 , 33 ]. Machine learning and AI are steadily gaining interest and over 10,152 papers were published in 2021 in the material engineering field alone.…”

In the 21st century, numerous numerical calculation techniques have been discovered and used in several fields of science and technology. The purpose of this study was to use an artificial neural network (ANN) to forecast the compressive strength of waste-based concretes. The specimens studied include different kinds of mineral additions: metakaolin, silica fume, fly ash, limestone filler, marble waste, recycled aggregates, and ground granulated blast furnace slag. This method is based on the experimental results available for 1303 different mixtures gathered from 22 bibliographic sources for the ANN learning process. Based on a multilayer feedforward neural network model, the data were arranged and prepared to train and test the model. The model consists of 18 inputs following the type of cement, water content, water to binder ratio, replacement ratio, the quantity of superplasticizer, etc. The ANN model was built and applied with MATLAB software using the neural network module. According to the results forecast by the proposed neural network model, the ANN shows a strong capacity for predicting the compressive strength of concrete and is particularly precise with satisfactory accuracy (R² = 0.9888, MAPE = 2.87%).

“…In a humid climate, the alkaline substances generated by hydration in cement-based materials will carbonize with carbon dioxide and water, resulting in a continuous decrease in the alkalinity of the material and a decrease in the pH value, which provides conditions for microbial reproduction. SO 4 2in the sludge is reduced by sulfate-reducing bacteria (SRB) to produce H 2 S gas, which reacts with bacteria to produce biological sulfuric acid (Hendi et al, 2017;Georgios et al, 2021). Various acids such as biological sulfuric acid and organic acid produced by microbial metabolism are continuously accumulated and infiltrated.…”

The concrete structure will be seriously eroded in a sewage environment, causing substantial economic losses. Therefore, it is of great significance to repair the existing corrosion structure. In order to quickly restore the mechanical properties and enhance the durability performance of eroded concrete structures, this paper develops a new composite high-durability mortar by adding polypropylene fibers, basalt fibers and impermeable agents, which can achieve the dual requirements of structural repair and protection. For the new material, this test set up a total of five groups of mixing ratios. This test analyzed the water absorption, mass loss rate, compressive strength and other performance indicators of the test block in the corrosive environment, and scanned and studied the microstructure of each mortar test block after corrosion. It was found that the new anti-corrosion mortar has relatively less crystallization, dense internal structure, and significantly lighter erosion. From the mechanical properties, the strength of ordinary polymer mortar after erosion decreased by 6%; high-durability mortar instead improved the strength by nearly 20%, showing better resistance to erosion. Taken together, the use of mineral dopants and water repellents can effectively enhance the strength and corrosion resistance of mortar, and the cost is low, with good prospects for engineering applications.
