Commercial sodium hydroxide (NaOH) and silicate (SS) have remained two of the leading alkaline activators widely used in producing geopolymer concrete, despite some identified negatives regarding their availability additional CO2 emissions relating to overall manufacturing process. This study reports viability developing concrete using a laboratory-synthesised silica fume (SF)-derived SS solution combination with NaOH at molarity 10M as an alternative binary alkali-alkaline activator Ground Granulated Blast Furnace slag (GGBS). The use SF development geoolymer will pave way for quality usage other high-silica content by-products from nature, industry, agriculture. In currently reported proof concept, four batches were produced different activator/precursor-A/P ratios (0.5 0.9) NaOH-SS/SH volume (0.8/1.2 1.2/0.8), establish impact on engineering performance. Two controls adopted ordinary mixes. performance was assessed slump compaction index (CI) tests, while Unconfined Compressive Strength (UCS) tensile splitting (TS) tests measured curing ages accordance appropriate standards. results indicated reduction values A/P ratio decreased, CI showed reversal trend slump. Consequently, mix GC2 attained highest UCS strength gain (62.6 MPa), displaying superiority alkali activation polymerisation process over CSH gel. Furthermore, variation more pronounced than SS/SH due its vital contribution geopolymerisation

This study aims to conduct comprehensive assessment of engineering and environmental attributes geopolymer pervious concrete with natural recycled aggregate. Pervious mixtures were fabricated different paste aggregate types for laboratory characterization at scales. As compared traditional cement concrete, mechanical strengths increase significantly when either coarse (NCA) or (RCA) is used. The replacement NCA RCA reduces strength but the advantage maintained. Micro-scale observations indicate that pastes have better bonding RCA. Life-cycle (LCA) results show lower global warming potential (GWP) eutrophication (EP), greater energy consumption (EC) acidification (AP) are achieved by geopolymer-based concrete. Photochemical ozone creation (POCP) found fly ash-based smaller metakaolin-based use brings benefit raw materials transportation stages, in addition avoiding landfilling preserving achieves best overall performance considering multi-criteria indicators regardless type.
