Enhancing corrosion resistance of RC pipes using geopolymer mixes when subjected to aggressive environment
TL;DR: In this article , the performance of reinforced concrete (RC) pipes is compared with OPC concrete mixtures with two different geopolymer concrete mixes based on different ratios of granulated blast furnace slag (GBFS), fly ash (FA), and pulverized red brick (RB) subjected to three different environments, ambient, tap water and an aggressive environment, and a solution of 10% magnesium sulfates + 5% chloride (MS-CL).

Mechanical and microstructural properties of GGBFS–RHA geopolymer concrete
TL;DR: In this paper, the suitability of ground granulated blast-furnace slag (GGBFS)- and rice husk ash (RHA)-based geopolymer concrete for construction of structural elements was evaluated.
Journal ArticleDOI
Workability, compressive strength, and microstructures of one-part rubberized geopolymer mortar
TL;DR: In this article , a one-part rubberized geopolymer mortar (ORGM) activated by a solid alkali activator was developed, and an experimental investigation was conducted on the setting time, fluidity, density, and compressive strength, of the ORGM, and the test findings were compared with two-part TRGM, which has a similar functional cost, a more convenient preparation method and a slower polymerization process.

Utilization of optimized microwave sintering to produce safe and sustainable one-part alkali-activated materials
TL;DR: In this article , safe and sustainable one-part alkali-activated slag mixes (OP-AAS) were prepared through an efficient microwave sintering for a mixture of active amorphous ground granulated blast furnace slag (GGBFS) and sodium hydroxide powder (NaOH).
New phosphate glasses containing industrial waste and their applications for building engineering
TL;DR: The use of phosphate as a glass former, instead of silicate, is a remarkable innovation, and according to the knowledge of the authors, no other work reports its utilization for building engineering purposes as discussed by the authors.

The greening of the concrete industry
TL;DR: The concrete industry is known to leave an enormous environmental footprint on Planet Earth as discussed by the authors, which contributes to the general appearance that concrete is not particularly environmentally friendly or compatible with the demands of sustainable development.
