Fly ash, GGBS, and silica fume based geopolymer concrete with recycled aggregates: Properties and environmental impacts

A Compensatory Approach for Enhancing the Strength and Durability of Green Concrete Composites (GCC) with Multiple Combinations of Recyclable Pozzolanic Materials (RPM)

“…The nature of micro silica may be highly ductile. Reference [25] It has been found that adding MS increases HPC's splitting tensile strength by 9%. Tensile strength is enhanced by the addition of MS because it strengthens the bond between the mineral aggregates and the binder matrix [27].…”

“…Generally speaking, each of them vary in their micro-structural features, elemental compositions and therefore, inevitably, in their chemical reactivity with water. This has created many conflicts in the selection of building materials for construction especially when some of them exhibit opposing effects on the intended qualities of mortar and concrete [21][22][23][24][25][26][27][28][29][30]. In this scenario, combining two or more types of mineral admixtures has shown to be a better option than using only one admixture for improving the properties of mortar and concrete [31][32][33][34][35][36].…”

“…On a preliminary investigation of the literature, it is revealed that most of the data-driven analytical research works rely on the morphological characterization techniques to evaluate the micro-structural evidence of physico-chemical compatibility of the composites [21][22][23][24]. Therefore, it is quite obvious to seek out the distinctive characteristics of various RPM composites using the inferences reported from the morphological studies [25][26][27][28][29][30].…”

“…Combined to the binary composites, studies on the tertiary combinations of RPMs are less-attempted. A few studies have reported the combined use of fly ash (FA), granulated slag (GS), and silica fume (SF) as ternary mixtures in lieu of OPC [25][26]. They found that the application of mineral admixtures along with composite cements, like Portland Pozzolana Cement (PPC) and Portland Slag Cement (PSC) can enhance the durability of concrete.…”

Sustainable cement-based materials blended with recycled water treatment sludge and other various waste products as binder: Characterization and environmental-economical impacts

“…Not only to reduce the environmental impacts caused by cement production, but also due to the shortage of natural resources, the development of environmentally-friendly, cost-effective and low-carbon building materials has become a topic of widespread concern Qaidi et al 2021;Hamada et al 2022). In this context, the use of waste by-products including silica fume (SF), ground granulated blast furnace slag (BFS) and fly ash (FA) as partial substitutions for Portland Cement (PC) has started to attract the attention of worldwide (Diniz et al 2022;Singh et al 2023;Wang et al 2023).…”
