“…For example, the electrical resistivity test provides a rapid indication of the likely resistance of concrete to CP and the likely subsequent rate of corrosion [54,56,57]. Nevertheless, electrical resistivity is much easier and faster than RCPT [58]. Water can transport salts, such as magnesium chloride, calcium chloride, and sodium chloride, which affect the service life of concrete structures [59].…”

This systematic literature review (SLR) aims to present and analyze the recent research on the effect of recycled glass (RG) on the durability of concrete applications in terms of transport properties, chemical attack, alkali-silica reaction (ASR), and freeze/thaw (FT). RG could be utilized in concrete as a replacement or addition in three forms, namely glass powder (GP), glass aggregate (GA), and glass fiber (GF). The methodology of this study was based on a criterion for the selection process of reviewed studies to assess and synthesize the knowledge of the durability of RG in concrete. The articles were assessed and screened, then 114 review articles were selected. The direction of utilization of RG in concrete depends on the type, particle size, and pozzolanic performance. The valorization of RG had a positive impact on the durability of concrete; however, the mutual synergy of multiple substitutions with glass also had better results. Nowadays, fine glass aggregate (FGA) could be promoted to be used as a partial substitute for sand due to the easiness of recycling. Furthermore, GF is strongly encouraged to be used in fiber concrete. An analytical framework that highlights the durability improvement of glass-modified concrete is presented. The results suggested that it is technically feasible to utilize glass as a part of concrete in the production of durable concrete. It provides a higher resistance to transport properties and chemical attacks by providing an extended lifespan. In addition, RG plays a great role in FT action in cold climates while it does not have a significant impact on ASR, provided refinement of glass results in the reduction of ASR and thus overcomes the expansion and cracks of concrete. However, up to 20% GP and up to 30% fine glass aggregate (FGA) could be replaced with cement and aggregate, respectively, to achieve a positive effect on durability based on the W/C ratio provided, not compromising the strength.

“…To improve the impermeability of cement‐based materials under nonhydrostatic pressure in which water enters capillary pores by capillary suction, 8 admixtures based on fatty acids are utilized 9–11 . Use of supplementary cementitious materials (SCMs) can also play an important role when permeability of under hydrostatic pressure, which is the situation that water enters capillary pores by pressure gradient, 8 needs to be improved 12–14 . However, using SCMs and admixtures based on fatty acids to improve impermeability may have some side effects on other properties of these materials 15–18 and these side effects should be considered.…”

Calcium stearate (CS) is effective to reduce permeability of different building materials under nonhydrostatic pressure but more actions need to be taken to shed light on its main and side effects on properties of cement‐based materials. This research project investigates the effect of CS on properties of these materials. Compressive strength analysis shows that the addition of CS at the dosage of 1% of cement weight reduces this parameter by approximately 20% but reducing water‐to‐binder ratio, and replacing 7.5% of cement weight with silica fume (SF) compensate for the strength loss caused by CS. Results of drying shrinkage test show that the addition of CS slightly increases drying shrinkage but replacing 7.5% of cement weight with SF can compensate for the negative effects of CS on drying shrinkage. Permeability analysis shows that CS is not as effective as SF and natural zeolite (NZ) to improve impermeability under hydrostatic pressure but it is more effective than SF and NZ to improve impermeability under nonhydrostatic pressure because the addition of CS at the dosage of 1% of cement weight reduces capillary water absorption by roughly 60%. Therefore, the simultaneous use of CS and these supplementary cementitious materials improves not only impermeability under hydrostatic pressure but also impermeability under nonhydrostatic pressure.

“…The lightening of concrete structures is among the important topics in the construction industry and civil engineering, being of great interest to engineers and researchers. Reducing building weight by using lightweight materials, in addition to saving money, time and energy, can reduce the damage caused by natural disasters such as earthquakes 1–4 . Lightweight structural members and bearing members in particular, could be fabricated using lightweight concrete, which will result in a decrease in the dimensions of the structures 5, 6 .…”

The porous lightweight aggregates adversely affect fresh properties of concrete, including slump and disruption of pumping concrete. Besides, this type of concrete is very susceptible to shrinkage cracking. In this study, two types of lightweight aggregates were used with a combination of two types of coating, including hydrophobic polymers ‐polyvinyl acetate and styrene‐butadiene rubber coatings. The coatings were applied in single and double layers. For the fresh concrete, the fresh properties of concrete, including slump flow, T50, flow time, and L‐Box were evaluated and for the hardened concrete, compressive strength, flexural strength, tensile strength, water absorption and shrinkage was studied. It was seen that the slump flow of coated lightweight aggregates increased by 10%, and also coating process reduced the water absorption of the aggregates up to 82%. The compressive strength increased by up to 21% for the coated aggregates. Scanning electron microscopy was also used to investigate the microstructure of the mortar‐aggregate interface. Microstructural images showed a uniform and dense interfacial zone of cementitious matrix‐aggregate for coated lightweight aggregates. Moreover, an improvement of 50–150 μm in the interfacial zone's thickness was seen for coated aggregates compared to uncoated aggregates.
