Sugar cane bagasse ash (SCBA) is an abundant byproduct of the sugar and ethanol industry. SCBA is generally used as a fertilizer or is disposed of in landfills, which has led to intensified environmental concerns. In recent years, SCBA research has mainly been focused on utilization in construction materials due to the abundance and pozzolanic characteristics of SCBA. In this paper, a comprehensive review of the state-of-the-art morphology, physical properties, chemical composition, and mineralogical composition of SCBA is presented. Studies indicate that SCBA is a potentially promising construction material. The applications of SCBA as a pozzolanic material, a new source for preparing alkali-activated binders, aggregates, and fillers in construction materials, are summarized. The impacts of SCBA on fresh and hardened concrete properties are highlighted, including the physical properties, mechanical strength, microstructure, and durability. Key factors that govern pozzolanic activity are discussed in detail, including calcination and recalcination temperatures, and durations, fineness, loss on ignition (LOI), and crystal silicon dioxide. Finally, further research on the optimal and broad utilization of SCBA in construction materials is recommended.

Utilization of industrial and agricultural waste products in the industry has been the focus of research for economical, environmental, and technical reasons. Sugar-cane bagasse is a fibrous waste-product of the sugar refining industry, along with ethanol vapor. This waste-product (Sugar-cane Bagasse ash) is already causing serious environmental pollution which calls for urgent ways of handling the waste. Bagasse ash mainly contains aluminum ion and silica. In this paper, Bagasse ash has been chemically and physically characterized, and partially replaced in the ratio of 0%, 5%, 15% and 25% by weight of cement in concrete. The Fresh concrete tests like compaction factor test, Slump cone test was obtained and hardened concrete tests like compressive strength, split tensile strength, flexural strength and Modulus of Elasticity at the age of 7 and 28 days was obtained. The result shows the increases in percentage of bagasse ash replacement, strength also increased.

In this study the Sugar cane bagasse ash (SCBA) was characterized for chemical composition, morphological and mineralogical properties. From XRF analysis it was found that the SCBA has SiO2, Al2O3, Fe2O3 and CaO content of 67.25%, 6.37%, 4.21% and 13% respectively and it has a very low LOI value of 0.34% and can be classified as Class F ASTM pozzolan according to ASTM C 618-2009. SCBA can be used as a pozzolanic material after grinding to less than 45 Micron. Based on the properties obtained from the characterization in this study it can be concluded that, utilization of SCBA in concrete will positively affect hardened concrete properties due to pozzolanic reaction, cementing properties and filling effect of SCBA. Moreover it will minimize the negative impacts associated with SCBA disposal.

In the present research, was studied the electrochemical behavior of AISI 304 stainless steel and Galvanized Steel embedded in Ternary Ecological Concrete made with partial substitution of Portland Cement (PC) by combination of Sugar Cane Bagasse Ash and Silica Fume (SCBA-SF) in 10, 20 and 30% and exposed to a 3.5% solution of Na2SO4 as an aggressive medium. For the design of the concrete mixtures was used ACI 211.1 method. Quality control tests of fresh and hardened concrete were carried out in accordance with the ONNCCE and ASTM standards. The electrochemical evaluation was carried out for a period of 6 months, using the techniques of corrosion potential Ecorr (ASTM C-876-15) and Linear Polarization Resistance-LPR- (ASTM G59) to determine the corrosion rate Icorr. The results indicate that AISI 304 SS has a high corrosion resistance from the curing stage to the end of monitoring, with values of Ecorr lower than -200 mV and negligible corrosion levels with values of Icorr below 0.1 µA/cm2, greater protection is identified in the Ternary Ecological Concrete with replacement of 30% of PC by SCBA-SF.

In the present investigation, the physical, mechanical and durability properties of six concrete mixtures were evaluated, one of conventional concrete (CC) with 100% Portland cement (PC) and five mixtures of Ecofriendly Ternary Concrete (ETC) made with partial replacement of Portland Cement by combinations of sugar cane bagasse ash (SCBA) and silica fume (SF) at percentages of 10, 20, 30, 40 and 50%. The physical properties of slump, temperature, and unit weight were determined, as well as compressive strength, rebound number, and electrical resistivity as a durability parameter. All tests were carried out according to the ASTM and ONNCCE standards. The obtained results show that the physical properties of ETC concretes are very similar to those of conventional concrete, complying with the corresponding regulations. Compressive strength results of all ETC mixtures showed favorable performances, increasing with aging, presenting values similar to CC at 90 days and greater values at 180 days in the ETC-20 and ETC-30 mixtures. Electrical resistivity results indicated that the five ETC mixtures performed better than conventional concrete throughout the entire monitoring period, increasing in durability almost proportionally to the percentage of substitution of Portland cement by the SCBA–SF combination; the ETC mixture made with 40% replacement had the highest resistivity value, which represents the longest durability. The present electrical resistivity indicates that the durability of the five ETC concretes was greater than conventional concrete. The results show that it is feasible to use ETC, because it meets the standards of quality, mechanical resistance and durability, and offers a very significant and beneficial contribution to the environment due to the use of agro-industrial and industrial waste as partial substitutes up to 50% of CPC, which contributes to reduction in CO2 emissions due to the production of Portland cement, responsible for 8% of total emissions worldwide.

This research evaluates the behavior corrosion of galvanized steel (GS) and AISI 1018 carbon steel (CS) embedded in conventional concrete (CC) made with 100% CPC 30R and two binary sustainable concretes (BSC1 and BSC2) made with sugar cane bagasse ash (SCBA) and silica fume (SF), respectively, after 300 days of exposure to 3.5 wt.% MgSO4 solution as aggressive medium. Electrochemical techniques were applied to monitor corrosion potential (Ecorr) according to ASTM C-876-15 and linear polarization resistance (LPR) according to ASTM G59 for determining corrosion current density (icorr). Ecorr and icorr results indicate after more than 300 days of exposure to the sulfate environment (3.5 wt.% MgSO4 solution), that the CS specimens embedded in BSC1 and BSC2 presented greater protection against corrosion in 3.5 wt.% MgSO4 than the specimens embedded in CC. It was also shown that this protection against sulfates is significantly increased when using GS reinforcements. The results indicate a higher resistance to corrosion by exposure to 3.5 wt.% magnesium sulfate two times greater for BSC1 and BSC2 specimens reinforced with GS than the specimens embedding CS. In summary, the combination of binary sustainable concrete with galvanized steel improves durability and lifetime in service, in addition to reducing the environmental impact of the civil engineering structures.

ABSTRACT The objective of this study is to assess the effect of the laminar inclusion on the physical and mechanical properties of sugarcane bagasse particleboard. We used the commercial panels of sugarcane bagasse produced in China. To evaluate the effect of the laminar inclusion was tested two wood species (Pinus and Eucalyptus) and two pressures (10 and 15 kgf.cm-2) along with a control (without laminar inclusion). The panels with laminar inclusion obtained improvements in the physical properties, with a significant reduction in the WA2h, WA24h and TS2h. There was a significant increase in the properties MOE and MOR parallel and Janka hardness, while the properties MOE and MOR perpendicular decreased significantly. The pinus and eucalyptus veneers inclusion resulted in similar results when added to the panel with a 10 kgf.cm-2 pressure. The use of 15 kgf.cm-2 pressure is not indicated for the pinus veneer inclusion in sugar cane bagasse panels. There was no effect of the pressure level when evaluating the eucalyptus veneer inclusion on the properties of the sugarcane bagasse panels.
