Abstract:The objective of this study was to evaluate the use of sugarcane bagasse ash (SCBA) as a partial replacement of cement in concrete for road pavement application. The study explored the pozzolanic activity of SCBA produced from three different processing methodologies (i.e., raw SCBA, controlled SCBA and post-processed SCBA). The experimental results revealed that SCBA produced by the controlled burning of sugarcane bagasse fiber (SBF) at 650°C and grinding (C-650), presented the maximum pozzolanic activity. However, this SCBA production process was deemed challenging for large-scale industrial application due to low SCBA yield (i.e., 3 to 6%). On the other hand, post-processing of raw SCBA, by burning at 450°C and grinding (P-450), produced a similar pozzolanic activity to that of SCBA C-650. Moreover, since post-processing of raw SCBA produced a significantly higher SCBA yield (i.e., 85 to 90%) than that of controlled burning of SBF, SCBA P-450 was selected for further investigation in concrete mixtures. The effect of different dosages of P-450 (i.e., 20, 30, and 40% cement replacement by weight) on concrete properties was evaluated. It was determined that concrete mixtures utilizing substitutions of 10% and 20% of cement with SCBA exhibited a similar compressive strength to that of control after 90 days of curing for Class-A and Class-B concretes, respectively. At higher levels of cement replacement, the compressive strength of concrete mixtures decreased proportionally at both, 28 and 90 days of curing; yet, the relative strength gain from 28 to 90 days increased. Furthermore, at 90 days of curing, surface resistivity of SCBA admixed concrete mixtures was superior to that of control for all cases. Finally, a cost analysis showed that a 10% cement replacement with SCBA in concrete could yield a reduction of per lane-mile cost of 0.75%. The total size of the described zip file is 174 MB. Files with the .xlsx extension are Microsoft Excel spreadsheet files. These can be opened in Excel or open-source spreadsheet programs. Docx files are document files created in Microsoft Word. These files can be opened using Microsoft Word or with an open source text viewer such as Apache OpenOffice. JPG files can be opened using the system's photo viewer. TIF files are high quality images files that can be viewed using the system's photo viewer. The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. The .csv file is often used for moving tabular data between two different computer programs, due to its open format. Any text editor or spreadsheet program will open .csv files. PNG files can be opened using the system's photo viewer. BAK files are back up files created by various programs. These files are backups of the CSV files. XRDML files are used for storing analytical data collected by external measuring devices. XRDML files store data in XML format. These files can be opened using an open source software such as notepad. PDFs are used to display text and images and can be opened with any PDF reader or editor. A SAS file is a program used to automate some operations in SAS statistical analysis software suite. A SAS program is saved as text. It contains commands, imported libraries, and datasets required to complete such operations. These files can be opened with SAS or an open source statistical program such as R Studio.
