چکیده
This paper focuses on the development of high-strength and eco-friendly one-part (i.e., dry-mix) alkali-activated mortar with ground granulated blast furnace slag as main precursor. In addition to slag, phyllite dust silica fume were used co-binders in binary ternary blends improve mechanical properties. Particle packing optimization was employed for mix proportioning achieve a compact matrix skeleton. The results revealed that 10% increase strength gained after adjusting particle an additional 20% increment observed blending other mineral admixtures. Ternary blend all three binders achieved compressive value 145 MPa (at 28 d age), which is highest reported materials. Additionally, present potential economic benefits because their ability replace lower-cost industrial side streams.

Use of Slag/Sugar Cane Bagasse Ash (SCBA) Blends in the Production of Alkali-Activated Materials
Blast furnace slag (BFS)/sugar cane bagasse ash (SCBA) blends were assessed for the production of alkali-activated pastes and mortars. SCBA was collected from a lagoon in which wastes from a sugar cane industry were poured. After previous dry and grinding processes, SCBA was chemically characterized: it had a large percentage of organic matter (ca. 25%). Solutions of sodium hydroxide and sodium...

متن کاملSELF-Cured Alkali Activated Slag Concrete Mixes- An Experimental Study
Alkali Activated Slag Concrete (AASC) mixes are manufactured by activating ground granulated blast furnace slag (GGBFS) using sodium hydroxide and sodium silicate solutions. The aim of the present experimental research was to investigate the effect of increasing the dosages of sodium oxide (Na2O, in the range of 4 to 8%) and the activator modulus (Ms) (i.e. the SiO2/Na2O ratio, in the range of ...
متن کاملThe Interfacial Transition Zone in Alkali-Activated Slag Mortars
The interfacial transition zone (ITZ) is known to strongly influence the mechanical and transport properties of mortars and concretes. This paper studies the ITZ between siliceous (quartz) aggregates and alkali-activated slag (AAS) binders in the context of mortar specimens. Backscattered electron (BSE) images generated in an environmental scanning electron microscope (ESEM) are used to identif...
