چکیده
This work presents a technical and economic study using sugar cane bagasse ash (SCBA) to partially replace Portland cement clinker. To evaluate the viability, replacement rates of 10, 20, 30% were used in experiments. The ashes following conditions: (i) as collected (AC), (ii) ground (G), (iii) re-burnt (RG). Three composition parameters mortar mix procedures: with water factor/fixed binder volume, weight, fixed flow. After feasibility analysis, benefit substitutions an analysis relationship between consumption acquired compressive strength, correlating possible costs, discussed. SCBA AC was not suitable for partial G presented satisfactory performance RG that best For same levels per cubic meter concrete reduced; from this, cost could be reduced by 8%, having value cement. Furthermore, use at inhibited alkali–silica reaction (ASR) concretes reactive basalt quartzite aggregate. (20 30%) (10 20%) ASR aggregate expandability Another point highlight durability shown cements SCBA, which, 900 days after accelerated test expansion alkali–aggregate reaction, maintained high flexural strength when compared results obtained before expansion. present concluded is feasible technical, environmental, perspective.

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 کاملBagasse ash and rice husk ash as cement replacement in self-compacting concrete
In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...
