چکیده
Abstract The resistance of alkali-activated materials (AAMs) to degradation processes, particularly the decalcification, was studied in this paper. ground granulated blast furnace slag using various activators with same activator dosage 6% Na 2 O by weight (sodium hydroxide, sodium waterglass and carbonate) subjected testing decalcification (immersion 6M NH 4 NO 3 ) for 84 days. reference samples were stored water. progress phenolphthalein technique, mechanical properties (compressive flexural strength), dilatometry analysis or measurements. results obtained compared CEM III/A 32.5R. significant loss mass along deterioration observed all binder types, still some AAMs showed better durability than cementitious one.

Microstructural and Mechanical Properties of Alkali Activated Colombian Raw Materials
Microstructural and mechanical properties of alkali activated binders based on blends of Colombian granulated blast furnace slag (GBFS) and fly ash (FA) were investigated. The synthesis of alkali activated binders was conducted at 85 °C for 24 h with different slag/fly ash ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100). Mineralogical and microstructural characterization was carried out b...

متن کاملUse 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...
