چکیده
Introduction: The construction industry uses a large quantity of natural materials in the production concrete. Although attempts to incorporate green concrete began years ago, not every building such today, and roadways, particularly, still rely on unsustainable materials. Methods: Therefore, this study used alternative materials, including fly ash, manufactured sand aggregates, different molarities alkaline activators, waste byproducts geopolymer white-topping pavement layer. Recent developments have led emergence geopolymers as distinct classes In 1990s, ash-based became more popular than other kinds, they are efficient compared Portland cement Results: Aluminosilicate gel can be obtained by combining ash solution. A comprehensive literature review was performed study. It examines its critical design parameters, solutions, curing temperatures, methods, workability, compressive strength under various environmental conditions. This provides unique opportunity for researchers understand how performs. Discussion: range conditions were investigated determine enhance use material variety ways. fresh characteristics mixes studied using slump Vee-Bee tests, cured determined flexural, compressive, flexural fatigue tests. results indicated that with high-molarity activators an excellent maximum resistance 5.1 N/mm 2 strength, properties, making it suitable roadway pavement.

15 صفحه اولTechBrief: Geopolymer Concrete
Geopolymer concrete—an innovative material that is characterized by long chains or networks of inorganic molecules—is a potential alternative to conventional portland cement concrete for use in transportation infrastructure construction. It relies on minimally processed natural materials or industrial byproducts to significantly reduce its carbon footprint, while also being very resistant to ma...

متن کاملFactors Influencing Compressive Strength of Geopolymer Concrete
To study effects of several factors on the properties of fly ash based geopolymer concrete on the compressive strength and also the cost comparison with the normal concrete. The test variables were molarities of sodium hydroxide(NaOH) 8M,14M and 16M, ratio of NaOH to sodium silicate (Na2SiO3) 1, 1.5, 2 and 2.5, alkaline liquid to fly ash ratio 0.35 and 0.40 and replacement of water in Na2SiO3 s...
