Self-compacting geopolymer concrete (SCGC) has emerged as a promising alternative to traditional due its environmental benefits. In SCGC, alkaline binders, such sodium hydroxide (NaOH) and silicate (Na₂SiO₃), play crucial role in influencing both workability strength. Notably, the ratio of binders significantly impacts overall performance SCGC. This study investigated five SCGC mixes with varying binder (A/B) ratios ranging from 0.40 0.60, incorporating 50% fly ash (FA) ground granulated blast furnace slag (GGBS). The included 14 M NaOH, superplasticizer (9 kg/m³), extra water (54 kg/m³) evaluate effect A/B on mechanical strength properties. results revealed that fresh properties 0.4, 0.45, 0.5 complied EFNARC guidelines, assessed by slump flow test, lowest T50cm recorded at 696 mm. mix an exhibited best performance, achieving compressive (CS) 38.3 MPa, splitting tensile (STS) 4.63 flexural (FS) 5.85 MPa. These findings suggest optimizes rheological NaOH concentration.

Replacing conventional materials with new recycled is one of the goals sustainable development, as it promotes creation environmentally friendly products while reducing amount waste to be treated. A common recyclable stream associated urban living glass, which typically comes from packaging or product containers. Although most this can reused and/or recycled, worth exploring alternative uses, especially for areas high fluctuations in glass production. An example would sudden increase tourist during season. To end, present work presents results life cycle assessment geopolymerization production cement tiles. The methodology includes estimation mass and energy balances by dividing whole process into several sub-processes (NaOH addition, consumption, etc.). NaOH addition was found burden-intensive process, a total damage 9 × 10−5 DALY per ton human health category, minor contribution all categories attributed electricity demands (7.7 19.4%). By comparing recycling, an environmental benefit 20 mPt 26 kg CO2 demonstrated, indicating process’s expediency. study valuable tool up-scaling processes towards circular economy.

In order to reduce the negative impact on environment caused by massive accumulation of red mud (RM) and Yellow River sand (YRS), new alkali-excited granulated blast-furnace slag (GGBS)/RM/YRS (AGRY) geopolymer cementitious materials were prepared combining RM YRS with GGBS in different ratios using sodium silicate as alkali exciter. The effects dosage curing conditions mechanical properties, hydration products, pore structure investigated analyzed terms cost carbon emissions. results showed that when was 40%, compressive strength AGRY material could reach 48.8 MPa at 28 d under standard curing, which properties comparable those without YRS. has a more compact internal structure, combination promotes chemical reaction Al Si elements generates (N, C)-A-S-H gel are key enhancement material. addition, is only 90% cement for same low emission accounting 43% emission.
