Evaluation Of Bagasse Ash As Cement And Sand Replacement For The Production Of Engineered Cementitious Composites (Ecc), Gabriel Arce, Marwa Hassan, Sujata Subedi, Ana Rivas, Samantha Hidalgo, Hugo Eguez
Data
The objective of this study was to develop novel Engineered Cementitious Composites (ECC) materials implementing sugarcane bagasse ash (SCBA). To this end, the effects on the mechanical and physical properties of ECC materials of: (1) Louisiana raw SCBA (RBA) as a partial and complete replacement of sand (i.e., class S mixtures); (2) Louisiana post-processed SCBA (PBA) as a partial replacement of cement (i.e., class C mixtures); and (3) Ecuador raw SCBA (EBA) as a partial and complete replacement of sand (i.e., class S-E mixtures) were studied. Sand replacement levels with RBA and EBA evaluated were 25, 50, 75, and 100% …

Eco-Friendly Stabilization Of Sulfate-Rich Expansive Soils Using Geopolymers For Transportation Infrastructure, Xinbao Yu, Anand Puppala, Miladin Radovic, Sayantan Chakraborty, Jungyeon Jang, Oscar Huang
Data
Traditional calcium-based stabilizers, such as lime, to stabilize sulfate-rich expansive soils, are lasting-challenges in geotechnical engineering. The biggest problem with using calcium-based stabilizers is that when calcium and water are exposed to sulfate-rich expansive soils, they form ettringite as an expansive mineral, which causes sulfate-induced heaving. The study aimed to investigate the feasibility of stabilizing sulfate-rich expansive soils using geopolymers for transportation infrastructure. Literature review on sulfate-induced heaving and sulfate-rich soils stabilized with geopolymers suggests a direction for how to stabilize sulfate soils using geopolymers. The engineering tests were conducted to determine the swell, shrinkage, and strength behavior of natural, …
