“…(2016) reported approximately 58% increase in initial and final setting times for mixture with 20% of SBA compared to that of the control mixture. 23 On the other hand, it is wellestablished that SBA is not as reactive as cement. Therefore, the addition of SBA replaced with cement contents can act as a retarder for concrete mixtures.…”

Sugarcane bagasse ash (SBA) is a supplementary material widely used around the world for improving mechanical and durability properties of concrete. Main aim of this study was to examine the potential of SBA for controlling alkali-silica reaction (ASR) in concrete incorporating reactive aggregates. SBA and reactive aggregates were acquired from local industry and quarry. Mortar bar specimens were cast to investigate various dosages of SBA (i.e., 10, 20, 30, and 40% by cement weight) for mitigating the alkali-silica reactivity expansion as per ASTM C1260. Petrography analysis of aggregates revealed the presence of deleterious minerals, which are prone to ASR. Strength activity index and thermal analysis results confirmed the pozzolanic activity of SBA. Mortar bar results showed 20 and 40% decrease in ASR expansion for specimens incorporating 10 and 40% of SBA by cement weight, respectively. Moreover, scanning electron microscopy analysis showed no sign of cracks due to ASR for specimens incorporating SBA. The improved behavior of specimens with SBA addition was due to alkali absorption and dilution process leading to low CaO/SiO 2 ratio, confirmed through energy disperse X-ray spectroscopy. Therefore, it can be envisioned that full-scale implementation of SBA addition in concrete mixtures could mitigate land filling of this by-product and lead toward the development of eco-friendly and sustainable technique for controlling the ASR associated damages in concrete structures.

“…Furthermore, unburned particles represented by the loss on ignition value are in the ash. The variability on the chemical composition of the SCBA can be attributed to the combustion process of the bagasse but also to the maturity and harvesting methods of the sugarcane [19].…”

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).

Fly ash is currently a problem in different companies, mainly in thermoelectric plants, which must follow a production and consumption model that involves reusing, renewing, and recycling, thus contributing to the circular economy. This work aims to evaluate the reactivity and compressive strength of different types of ashes in concrete monoliths. For this purpose, sugarcane bagasse (SCBA), bituminous coal (BC), and untreated hazardous waste (RUD) were evaluated as replacements for cement. Monoliths and mortars have been manufactured in different mixtures, taken to a curing room, and their compressive strength and reactivity have been determined at different times (up to 28 days for the monoliths and up to 90 for the mortars), mainly in order to check the formation of calcium silicate hydrate (CSH) gels. In the monolith tests, the best performances have been with SCBA and BC, which have been used for the manufacture of the mortars. On day 56, the behavior of the replacement of 30% fly ash (15% BC:15% SCBA) presents a type H mortar behavior, with better results than the control. By day 90, all replacements had the same resistance as M mortars and even higher resistances than the control. This demonstrates the feasibility of its use in the production of Portland cement for the manufacture of low‐performance inputs. This implies the possible reduction of impacts, both in waste disposal sites and in emissions caused by the construction industry, thus contributing to the circular economy.
