“…After 28 days, the slowest reaction occurs leading to post-enhance the compressive strength of the cements. Furthermore, it can be observed that a higher amount of BRHA added to the cement results in lowering the compressive strength, which agrees well with other researches [9,10,[14][15][16]. This is probably because the increment of silica to alumina ratio (SiO2/Al2O3) in concrete due to the large amount of SiO2 in BRHA exhibits the geopolymer reaction and the gelation process [16].…”

“…Furthermore, as BRHA prepared from agricultural waste is almost costless, the partial replacement of cement can lower the concrete construction cost. Recent literatures [9,10] have reported that the increase in RHA used in cement led to a decrease in concrete compressive strength, so the acceptable replacement ratio must be considered. Moreover, the effects of BRHA replacement on corrosion and chloride penetration are also investigated.…”

In this work, the black rice husk ash (BRHA), a pozzolanic material, was used as a partial replacement in concrete with the weight percentages of 0%, 10%, 20%, 30%, 40% and 50% for enhancing the corrosion resistivity in the marine environment. The compressive strength, corrosion by accelerated corrosion test by impressed voltage (ACTIV), and chloride (Cl−) penetration of concrete specimens were investigated after 28 days of curing. For corrosion and chloride penetration analyses, the 20% of BRHA replacement specimen was the most effective concrete specimen because the deformation was not observed within 19 days of the test. The cement specimens with lower BRHA percentages were cracked due to the development of stress by the rust formation. For higher BRHA percentages, the protective Fe2O3 was dissolved due to the acidic environment caused by higher chloride accumulation in the cement specimens. The steel rebar was then aggressively attacked by the chloride and it was finally broken. Therefore, the optimization of the BRHA percentage is needed to minimize corrosion. However, the longer curing time of 20% BRHA replacement specimen is required for increasing the compressive strength because its compressive strength is slightly lower than the standard.

“…During the technology development, the quality of PCPs is increasing with the improvement of their compressive strength and noise reduction. PCPs, in contrast to conventional concrete pavement, have a high percentage of voids, between 15% and 25% [14]. Figure 2 shows the position of voids spaces,coarse aggregates and cement paste in PCPs.…”

Pervious concrete pavements (PCPs) have been widely accepted as a green infrastructure solution for urban areas. Currently, pervious concrete is commonly used in permeable pavement systems such as roadways, sidewalks, driveways, parking lots, and other light-duty flatwork applications. However, the main disadvantage of this type of pavement is that it loses permeability over time due to clogging and lower compressive strength due to the pore's structures. These critical issues are the topic of this review paper. Laboratory test results relevant to the compressive strength, clogging and maintenance are discussed in detail. This review aims to present a compilation of prominent findings of studies focused on compressive strength, clogging and maintenance of PCPs. Note that PCPs with higher compressive strength must be used on roads with high traffic volumes. Subsequently, periodic maintenance is necessary to prevent sediment clogging and maximise the life of PCPs. Based on this review paper, the area of need for future research are identified.

“…Since the use of pozzolans usually reduces the compressive strength of concrete, in order to reduce this negative effect, nanoparticles are used in concrete [14]. Nanoparticles can increase the density of particles in concrete, thereby increasing the density of nanostructures in concrete and improving its mechanical properties.…”

In recent years, natural pozzolans have been proposed as a way to improve the mechanical and biocompatible properties of concrete. This study investigated the effects of different amounts of nanoparticles, coal slag pozzolan, and their combination on the mechanical properties and durability of concrete. For each mixed design, nine cubic samples of 10 × 10 × 10 cm and 30 × 15 cm were made and then cured in water for 28 days before being tested for compressive and tensile strength. According to the results, pozzolan at about 5% of cement weight increased the compressive strength of concrete compared to samples without pozzolan. Nanoparticles of FeNi3 greatly enhanced the compressive and tensile strength of concrete in most samples containing nanoparticles. The compressive and tensile strength of 28-day concrete increased by 27% and 18%, respectively. Pozzolan (10%) and 2% of FeNi3 (CP10F2) in concrete also reduced the water absorption of the samples, which can improve the durability parameters of concrete. In concrete exposed to sulfuric acid, sample CP0F2 (2% of FeNi3 nanoparticles) had a positive effect on compressive strength, and samples containing 2% of FeNi3 nanoparticles had higher compressive strength than those with pozzolan replacing cement. The simultaneous use of coal slag and FeNi3 nanoparticles has increased the mechanical properties and durability of concrete in addition to reducing cement consumption.
