“…Another strategy is the utilization of waste materials such as glass [ 23 ], PET bottles or containers [ 24 ], ceramic tiles and coverings, ceramic sanitary products [ 25 ], ceramic clay bricks [ 26 ], tyres and rubber [ 27 ], concrete residues [ 28 ], agricultural wastes [ 29 , 30 ], metallurgy slags [ 31 , 32 , 33 ], industrial wastes [ 34 , 35 , 36 ], or coconut husks [ 37 ]. All these additions proportionate a positive environmental impact due to the reutilization of materials and products which had completed their service life.…”

The present research work shows the effect on the carbonation of Portland cement-based mortars (PC) with the addition of green materials, specifically residues from two groups: agricultural and industrial wastes, and minerals and fibres. These materials have the purpose of helping with the waste disposal, recycling, and improving the durability of concrete structures. The specimens used for the research were elaborated with CPC 30R RS, according to the Mexican standard NMX-C-414, which is equivalent to the international ASTM C150. The aggregates were taken from the rivers Lerma and Huajumbaro, in the State of Michoacan, Mexico, and the water/cement relation was 1:1 in weight. The carbonation analyses were performed with cylinder specimens in an accelerated carbonation test chamber with conditions of 65 +/− 5% of humidity and 25 +/− 2 °C temperature. The results showed that depending on the PC substitutions, the carbonation front advance of the specimens can increase or decrease. It is highlighted that the charcoal ashes, blast-furnace slags, and natural perlite helped to reduce the carbonation advance compared to the control samples, consequently, they contributed to the durability of concrete structures. Conversely, the sugarcane bagasse ash, brick manufacturing ash, bottom ash, coal, expanded perlite, metakaolin, and opuntia ficus-indica dehydrated fibres additions increased the velocity of carbonation front, helping with the sequestration of greenhouse gases, such as CO2, and reducing environmental pollution.

“…The defense mechanism in the case of sulfate salt penetration into the concrete is mainly based on the buffering effect of the binder components that maintain the alkaline environment of the concrete. The migration of sulfate ions with significant concentration into the concrete structure poses a risk of the formation of corrosive chemicals, in particular: ettringite (C 3 A•3CaSO 4 •32H 2 O) and gypsum (CaSO 4 •2H 2 O), as indicated by the authors [25][26][27].…”

In light of the scientific research, the corrosion of concrete structures is one of the main problems that may reduce their durability due to the negative impact of the natural environment. The paper analyzes the influence of the type of component on the selected properties of lightweight concrete subjected to the influence of aggressive liquids. Four concrete mixes were prepared with a granular aggregate made of foamed glass (GEGA) and aggregate made of sintered fly ash (GAA) with the use of a mineral additive: silica fly ash. The prepared lightweight concrete after one year was exposed for 60 days to the following environments: strong acid—HCl, 1% and 2% concentration, weak acid—CH3COOH, 1% and 2% concentration, and an aqueous salt solution of Na2SO4, 1% and 2% concentration. Then, the compressive strength was tested, and the microstructure analysis of the ready-made lightweight concrete (LWC) was performed. The degree of penetration of aggressive solutions into the cracks of the samples was assessed by means of applying 1% phenolphthalein solution. Changes in the weight of lightweight concrete samples after the test period were estimated. The obtained test results indicate that the decrease in the durability of lightweight concrete can be classified as a long-term process. Concrete with GEGA and GAA showed high resistance to aggressive environments. Moreover, the environment containing chlorides turned out to be the most aggressive, while the environment containing sulfates proved to be the least aggressive. The higher the concentration of the destructive factor was, the faster the corrosion process went. This has been proven by measuring the pH using phenolphthalein and carrying out microscopic examination. Concretes containing aggregates made of foamed glass and sintered fly ash are suitable for use both in traditional construction and in facilities exposed to an aggressive environment (e.g., in the chemical industry and at gas stations).

“…For this reason, they have tried to find solutions that delay or reduce the emissions of CO 2 produced by the cement industry in the world. In the present research, Sugar Cane Bagasse Ash (SCBA) and Silica Fume (SF) were used as alternative materials to Portland Cement due to their pozzolanic characteristics [7][8], in addition It is known that one of the major problems of the integrity of reinforced concrete structures is the corrosion of steel [9][10][11][12][13][14], but it has been reported that the use of this type of pozzolanic materials increases the corrosion resistance of concrete reinforcing steel exposed to aggressive media such as sulfate and chloride ions and contribute to a reduction in CO 2 emissions, concrete that are considered sustainable, ecological or green [15][16][17][18][19][20]. Four concrete mixes were designed in accordance with ACI 211.1, the first being 100% CPC and the remaining three were made with partial substitutions in percentages of 10%, 20% and 30% of the CPC by combinations of CBCA and HS After its performance, they were placed in two different media, control medium (drinking water) and a 3.5% MgSO 4 solution, and tests of F´c and Modulus of elasticity performed at 7, 14 and 28 days.…”

In the present research work, four concrete mixtures were designed according to the ACI 211.1 method, the first as a control mixture, with 100% CPC, and the remaining three elaborated with partial replacement of the CPC by combinations of Sugar Cane Bagasse Ash and Silica Fume (SCBA-SF) in 10%, 20% and 30% (Green Concrete). The tests carried out on the four mixtures were physical properties (Slump, Temperature, Density) and mechanical properties as Compressive Strength (F'c) and Modulus of Elasticity, according to the ASTM and ONNCCE standards, the study specimens were exposed in water, as a control medium and a 3.5% solution of MgSO 4 as an aggressive medium for a period of 28 days. The results obtained indicate a good performance of the Green Concrete in comparison with the control mixture, in particular the Green Concrete made with 10% and 20% substitution of CPC by SCBA-SF.
