Due to the associated economic, environmental, and performance advantages, using natural pozzolans as a substitute for cement is regarded as a standard guidelines in the construction sector. In order to achieve, it is beneficial to use GGBS in the production of concrete, which was identified as the most effective supplementary cementitious material in resisting environmental threats. According to the literature review, GGBS concrete is more impermeable than PPC concrete (concrete with fly ash) or pure OPC concrete. However, it has the potential to increase the strength of concrete, which is a significant disadvantage of pervious concrete. Hence this study investigates the variation of strength and permeability of pervious concrete in order to obtain the optimal proportion of GGBS inclusion in concrete production. Along with that, the research uses artificial neural networks to estimate the compressive strength, water permeability, and porosity of pervious concrete blended with several proportions of GGBS. The study results showed that the inclusion of larger aggregate sizes significantly increased the strength but the effect of adding GGBS in partial replacement of cement could not. As a result, GGBS might replace some of the cement in concrete without significantly altering its mechanical qualities. Further, the developed ANN models outperformed the conventional MLR model and it can act as a useful alternative to analytical models for predicting strength and permeability values in pervious concrete.

“…A large number of voids makes pervious concrete relatively lightweight (density ranges between 1600 and 1900 kg/m 3 ). According to [ 25 ], the porosity of PCO ranges from 15% to 35%, and the compressive strength ranges from 2.8 to 28 MPa [ 17 , 26 , 27 ]. The flow rates of water flowing through pervious concrete differ depending on the aggregate particle size and density of the mix, but usually it ranges between 504 and 4392 cm/h.…”

Pervious concrete (PCO) has many advantages and applications, such as water pooling reduction, noise attenuation, replenishment of groundwater reserves, etc. However, the use of pervious concrete is limited due to its low compressive strength and durability, especially as a result of portlandite leaching from concrete exposed to flowing water. The effects of active additives (nano SiO2 (NS) spent catalyst generated at the fluid catalytic cracking unit (FCCCw) and paper sludge waste burned at 700 °C (PSw)) along with particle size distribution of the coarse aggregate on the properties and durability of pervious concrete were determined in the research. Active additives used in the binder were found to reduce portlandite leaching from concrete exposed to flowing water to significantly increase the resistance of concrete to freezing and thawing cycles and to increase sound absorption, compressive strength and infiltration rate. In addition, industrial waste (FCCCw and PSw) used as active additives significantly reduced the use of clinker in concrete applied in the construction of water pervious systems. The coarse aggregate size distribution had the greatest effect on the density, ultrasound pulse velocity (UPV), porosity, compressive strength and infiltration rate of pervious concrete.

“…At the same time, superplasticizer is a vital fixing in HPC prepared by copper slag to give great functionality and better consistency. The utilization of Fayalite slag in concrete clinker formation and the impacts of copper slag on the properties of concrete have been examined by numerous analysts [22][23][24]. A few works detailed the mechanical properties of concrete prepared using fayalite slags substitution for sand, and crushed stones show more development than ordinary cement [25][26][27].…”

Mineral admixtures are frequently utilized as cement substitution materials in high-performance concrete (HPC), and so many studies have explored the influence of mineral admixtures on the rheological behavior of HPC. Investigations were done to examine the impact of nanosilica less than 100 nm on HPC by substituting copper slag at a fixed substitution of forty percent for fine aggregate. Concrete samples were cast by substituting cement with nanosilica at (0.5, 1, 1.5, 2, 2.5, and 3) percentages. Examinations on mechanical properties and durability were done on specimens. The above tests demonstrated an increase in water demand because of the increase in the nanosilica substitution percentage. Mechanical and durability properties were improved at a larger rate with the incorporation of nanosilica. The outcomes indicated that colloidal nanosilica is an effective material that enhances the microstructure and acts as a catalyst for pozzolanic activity. The incorporation of nanosilica improves the strength up to two percentage substitution level.
