Sugar Cane Bagasse Ash

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.

Sugar Cane Bagasse Ash

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.

Sugar Cane Bagasse Ash

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.

Electrochemical Evaluation

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.

Potential Use

Sugar cane bagasse ash (SBCA) is a fibrous waste-product of the sugar refining industry. It is generated as a combustion by-product from boilers of sugar and alcohol factories. This is composed mainly by silica and this by-product can be used as a mineral admixture in mortar and concrete. This waste product is already causing serious environmental pollution which calls for urgent ways of handling the waste. On the other hand, the boost in construction activities in the country created shortage in most of concrete making materials especially cement, resulting in an increase in price. This study examined the potential use of sugarcane bagasse ash as a partial cement replacement material. In this paper, Bagasse ash has been chemically and physically characterized, in order to evaluate the possibility of their use into concrete.

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.

Sugar Cane Bagasse Ash

The environmental impact of cement production increased significantly in the previous years. For each ton of cement produced, approximately a ton of carbon dioxide is emitted in decarbonation (50%), clinker furnace combustion (40%), raw materials transport (5%), and electricity (5%). Green strategies have been advanced to reduce it, adding natural or waste materials to substitute components or reinforce the mortar, like fibers or ashes. Sugar cane bagasse ash is a by-product generated from sugar boilers and alcohol factories with capacity to be used in concrete production. Composed mainly of silica, it can be used as mortar and concrete mineral admixture, providing great economic and environmental advantages, particularly in regions with sugar culture and industrial transformation like Brazil. In this research, a study of partial substitution of Portland cement by sugar cane bagasse (SCB) is analyzed, in order to reduce clinker in concrete volume, responsible for high emission of CO2 to the atmosphere. An experimental campaign with cementitious pastes was carried out to evaluate the durability properties’ changes due to SCB ash use. Samples containing 15% of sugarcane bagasse ash unveiled good results in terms of durability, indicating that concrete structure with sugar cane ash research is a new and important scientific topic to be highlighted.
