“…LD slag aggregates demonstrated higher strength values compared to natural coarse aggregates, attributed to their lower crushing as well as Los Angeles abrasion value. This indicates that LD slag aggregates have a higher resistance to wear and tear, which ultimately enhances their overall durability [21,41]. The trend of the flexural strength results is that the strength decreased on increasing the percentage replacement of marble dust.…”

“…(7 and 28 days). This might be due to the irregular shape and uneven surfaces of slag aggregates improved the interfacial transition zone (ITZ), resulting in a sturdy concrete matrix [21,37]. The optimum replacement was noted at 10% cement replacement with marble dust and 35% coarse aggregates with LD slag replacement.…”

“…Slag management must be sustainable if the steel industry is to have a minor negative environmental impact. To lessen the quantity of the trash that ends up in landfills, efforts are being made to reuse slag for use in construction or to use it in the production of cement or other building materials [19][20][21][22].…”

“…Only one-fourth of the LD Slag generated in India is actually utilized; the remainder is disposed of in landfills. Singh et al [21] replaced the coarse aggregate with LD slag at different percentage replacement to evaluate the mechanical and durability properties of concrete. They concluded that up to 75% replacement of coarse aggregate showed improved strength and durability properties.…”

Nowadays, the development of infrastructure is in full swing, which exploits natural resources and causes environmental pollution. Furthermore, cement is the most essential commodity for construction material mainly concrete, and its production is rapidly increasing to fulfil the demand for construction. The cement production is regarded as the one of the key causes of CO2 emissions, which adversely affect the atmosphere by causing global warming. In addition to this, the ecosystem may suffer from marble quarrying and construction material processing. Nonetheless, waste marble can be used as a by-product if managed in accordance with regional, national, and international environmental laws. On the other hand, Currently, LD slag is disposed of in landfills, which exacerbates the scarcity of available land and contaminates groundwater through the leaching of heavy metals. The waste materials have the potential to be used in the development of infrastructure materials. The infrastructure development has aggravated the issue of rainwater runoff and flash flooding in rainy seasons because of inappropriate drainage. The elimination of sand in pervious concrete reduces its strength performance its practical applications are still limited. This study is aimed toward the permeability improvement of conventional pavement concrete by the implementation of pervious concrete and also to improve its strength characteristics. In this study, an attempt has to be made to replace the cement with marble dust up to a replacement level of 0% to 20% with an interval of 5%. Also, natural aggregate is replaced with Linz-Donawitz (LD) slag by 5%, 15%, 25%, and 35%. From the study, it is found that the use of marble dust and LD slag improves the strength properties, but reduces the permeation properties.

“…; external factors mainly include ambient temperature, humidity, carbon dioxide content, and corrosive environment. The durability problems of concrete in practical applications mainly include [ 5 , 6 ]: (1) carbonation of concrete and corrosion of steel bars; (2) freeze–thaw damage of concrete; (3) erosion of chemical medium; (4) corrosion of physical concrete wear; (5) alkali–aggregate reaction [ 7 , 8 ]. Among the many durability problems, more attention has been paid to concrete carbonation [ 9 , 10 , 11 ].…”

The use of tricyclic copolymer latex (AMPS) can effectively improve the carbonation resistance of sulphoaluminate cement. This paper investigated polymer AMPS and polycarboxylic acid to modify sulphoaluminate cement materials by exploring the carbonation level of sulphoaluminate cement paste and mortar and the strength before and after carbonation. Then, the optimal dosage of polymer and polycarboxylic acid was obtained so that the carbonation resistance of sulphoaluminate cement reached the best state. The compressive strength was significantly improved by adding AMPS for sulphoaluminate cement paste and mortar. After carbonation, the strength decreased and combined with the carbonation level; it was concluded that the carbonation resistance of sulphoaluminate cement materials was the best when the optimal dosage of AMPS and polycarboxylic acid was 5% and 1.8%, respectively. Due to the addition of AMPS, the hydrated calcium aluminosilicate (C-A-S-H) and hydrated calcium silicate (C-S-H) gels, generated by the hydration of sulphoaluminate cement and the surface of unreacted cement particles, are wrapped by AMPS particles. The water is discharged through cement hydration. The polymer particles on the surface of the hydration product merge into a continuous film, which binds the cement hydration product together to form an overall network structure, penetrating the entire cement hydration phase and forming a polymer cement mortar with excellent structural sealing performance. To prevent the entry of CO2 and achieve the effect of anti-carbonation, adding polycarboxylic acid mainly improves the sample’s internal density to achieve the anti-carbonation purpose.
