“…Furthermore, geopolymer-based materials possess comparable or even superior mechanical properties and durability, especially excellent resistance to chemical corrosion and thermal properties [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Research findings revealed that geopolymers blended with various mineral additives show a significant improvement in mechanical properties and durability at various temperature conditions [ 7 , 8 ].…”

“…Research findings revealed that geopolymers blended with various mineral additives show a significant improvement in mechanical properties and durability at various temperature conditions [ 7 , 8 ]. The results advocate that geopolymer mixtures with desired properties can be designed for ambient temperature curing condition with minerals additives, which may further promote them as an environmentally friendly construction material [ 7 , 8 , 9 ]. Geopolymer-based binders show inherently superior fire resistance as compared to Portland cement-based binders.…”

This paper presents an experimental investigation on geopolymer coatings (GPC) in terms of surface protection of civil structures. The GPC mixtures were prepared with a quadruple precursor simultaneously containing fly ash (FA), ground granulated blast-furnace slag (GBFS), metakaolin (MK), and Portland cement (OPC). Setting time, compressive along with adhesive strength and permeability, were tested and interpreted from a perspective of potential applications. The preferred GPC with favorable setting time (not shorter than 120 min) and desirable compressive strength (not lower than 35 MPa) was selected from 85 mixture formulations. The results indicate that balancing strength and setting behavior is viable with the aid of the multi-componential precursor and the mixture design based on total molar ratios of key oxides or chemical elements. Adhesive strength of the optimized GPC mixtures was ranged from 1.5 to 3.4 MPa. The induced charge passed based on a rapid test of coated concrete specimens with the preferred GPC was 30% lower than that of the uncoated ones. Setting time of GPC was positively correlated with η[Si/(Na+Al)]. An abrupt increase of setting time occurred when the molar ratio was greater than 1.1. Compressive strength of GPC was positively affected by mass contents of ground granulated blast furnace slag, metakaolin and ordinary Portland cement, and was negatively affected by mass content of fly ash, respectively. Sustained seawater immersion impaired the strength of GPC to a negligible extent. Overall, GPC potentially serves a double purpose of satisfying the usage requirements and achieving a cleaner future.

“…Geopolymer has emerged as an innovative technology for sustainable building and civil engineering; pioneered by Joseph Davidovits [1,2]. It is the product of "geopolymerisation" that is a reaction at room temperature or slight high temperature between aluminosilicate powder as precursors and a high alkaline solution.…”

“…As well as Portland binder's, geopolymer materials are attractive because of their excellent mechanical properties, durability and thermal stability. In addition, owing to their low calcium content, they are more resistant to acid, and their manufacture requires less energy, limiting the environmental footprint [1][2][3]. Despite the many advantages quoted by numerous authors, significant difficulties still appear in effective use of geopolymer binders due to many reasons and mostly to their behavior overtime.…”

Concrete is a building material that is widely used worldwide. The main ingredient in concrete is cement, which causes high CO 2 emissions into the atmosphere. An alternative to conventional cement-based concrete is geopolymer concrete. This material is inadequately researched to be used as a building material. In this work, mechanical properties of geopolymer-based concrete are investigated to estimate its potential in construction industry.
