Assessing Ground Vibration Caused by Rock Blasting in Surface Mines Using Machine-Learning Approaches: A Comparison of CART, SVR and MARS

Gbétoglo, Charles Komadja; Rana, Aditya; Adissin Glodji, Luc; Anye, Vitalis; Jadaun, Gajendra; Azikiwe Onwualu, Peter; Sawmliana, Chhangte (Sustainability, 2022-08-10)

Ground vibration induced by rock blasting is an unavoidable effect that may generate severe damages to structures and living communities. Peak particle velocity (PPV) is the key predictor for ground vibration. This study ...
Assessment of stability of a Himalayan road cut slope with varying degrees of weathering: A finite-element-model-based approach

Gbetoglo Komadja, Charles; Sarada Pradhan, Prasad; Amulya Roul, Ratna; Babatunde, Adebayo; Jean Habinshuti, Baptiste; Luc Glodji, Adissin; Azikiwe Onwualu, Peter (Heliyon, 2020-11)

Slope stability assessment is essential for safe and sustainable development widely applied in mining, civil, and environmental engineering projects around the world. This study aimed to conduct a stability analysis of a ...
Development of Sustainable and Eco-Friendly Materials from Termite Hill Soil Stabilized with Cement for Low-Cost Housing in Chad

Aboubakar Mahamat, Assia; Linda Bih, Numfor; Ayeni, Olugbenga; Azikiwe Onwualu, Peter; Savastano, Jr, Holmer; Oluwole Soboyejo, Winston (Buildings, 2021-02-26)

This paper explores the effects of cement stabilization (5, 10, 15 and 20 wt%) on the structural and mechanical properties (compressive/flexural strengths and fracture toughness) of abandoned termite mound soil. The crystal ...
The Effect of Bone Ash on the Physio-Chemical and Mechanical Properties of Clay Ceramic Bricks

Linda Bih, Numfor; Aboubakar Mahamat, Assia; Chinweze, Chukwuemeka; Ayeni, Olugbenga; Jechonias Bidossèssi, Hounkpè; Azikiwe Onwualu, Peter; E. Boakye, Emmanuel (Buildings, 2022-03-10)

Bone ash waste can be used to fabricate clay ceramic bricks, consequently managing their pollution of the environment. This is because bone ash (BA) and clay predominantly consist of calcium and alumina-silicate, respectively, ...
