Clinker-free CaO-activated silica fume as a cementitious binder for pavement application

Lahoti, Mukund (Elsevier, 2024-10)

Ordinary Portland cement (OPC) production requires heating limestone up to 1450 °C and produces 0.5–0.9 kg of carbon dioxide for every 1 kg produced. Moreover, the massive volume of cement manufactured around the world ...

Resilience Based Earthquake Design of Buildings: Current Practice, Problems, and Opportunities in Indian Scenario

Muthukumar, G. (ASCE, 2018)

Resilience based design (RBD) gives an advantage in designing for both direct and indirect losses. It was observed that most significant losses to the economy is due to indirect losses incurred due to long downtime—inability ...

Influence of Shear Core Curtailment on the Structural Response of Core-Wall Structures

Muthukumar, G.; Kumar, manoj (Springer, 2018-08)

Shear walls and shear cores are the major lateral load resisting elements in multi-storeyed framed structures because of their proven track record in mitigating the damage under severe earthquake ground motions including ...

Post-Earthquake Assessment of Buildings Using Deep Learning

Muthukumar, G. (2019-07)

Classification of the extent of damage suffered by a building in a seismic event is crucial from the safety perspective and repairing work. In this study, authors have proposed a CNN based autonomous damage detection model. ...

Design and Performance Criteria for Fire-Resistant Design of Structures – An Overview

Muthukumar, G. (Springer, 2020-09)

Concrete, despite being inherently fire resistant, cannot be considered as a fire-proof material. It undergoes substantial variation in its characteristics during exposure to elevated temperatures. These variations may ...

Alkali-activation potential of stone wastes

Bhunia, Dipendu (Elsevier, 2023-03)
