Performance of ecological cement-based composites containing sugarcane bagasse ash – A review
Bibliographic record
Abstract
In recent years the sugarcane bagasse ash (SCBA) has been used to produce environmentally-friendly cement-based composites. The SCBA is an agricultural waste which is obtained as by-product from the combustion of sugarcane bagasse in sugar mills. This ash is available in large quantities in emerging countries such as Brazil, India, Thailand and Mexico, and its disposal in open dumps is causing different environmental issues. A number of researchers report that the SCBA from sugar mills needs a post-treatment such as recalcination, grinding, sieving or the combination of these methods in order to enhance its pozzolanic activity. After processing, up to 30% of SCBA can be used as a partial Portland cement replacement in composites. This replacement may cause microstructural changes in the cementitious matrix and the improvement of the mechanical properties in composites containing it. However, studies on the durability of such composites are required. This paper focuses on the performance of cement-based composites containing treated SCBA. The microstructural, mechanical and some durability properties of those composites are discussed. This literature review is useful to carry out further researches about the durability of reinforcement embedded in cement-based composites containing SCBA (SCBAC).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
