Bio-Based Self-Healing Concrete for Sustainable and Durable Concrete Infrastructure
( Qatar University Press , 2023 , Conference Paper)In this study, bio-self-healing concrete was manufactured using a natural phenomenon called microbial-induced calcium carbonate precipitation (MICP). The bacillus cereus bacteria isolated from Qatari soil was used for this ... -
Sustainability Driven Strategy for Achieving Sustainable Infrastructure: Musaimeer Pumping Station and Outfall Project
( Qatar University Press , 2023 , Conference Paper)The increasing emphasis on global sustainability issues such as climate change, loss of biodiversity, deforestation, and water scarcity has provided a strong mandate for the construction industry to incorporate sustainable ... -
A Markovian-Genetic Algorithm Model for Predicting Pavement Deterioratio
( Qatar University Press , 2023 , Conference Paper)Pavement structures are constantly deteriorating due to many distresses, for instance cracks and rutting that are initiated and expanded. Deterioration models of pavement structures is an important component of pavement ... -
Self-compacting Backfills using Fly Ash and Dredged Marine Sediments for Public Work Applications
( Qatar University Press , 2023 , Conference Paper)Sediment accumulation at the bottom of ports disrupts maritime activities and disturbs the physicochemical balance of water bodies. In France, the maintenance of the 6500-kilometer long coastline would require the extraction ... -
Efficacy in developing a Sustainable, Resilient, and Interdependent Infrastructure System in the Gulf Region
( Qatar University Press , 2023 , Conference Paper)The world is becoming increasingly interconnected, and the exchange of information, knowledge, and services assists in developing and managing many aspects of the built environment. Sustainable, resilient, and interdependent ... -
Potential Utilization of Alternative Construction Materials in Qatar, in lieu of Conventional Washed Sand
( Qatar University Press , 2023 , Conference Paper)Natural sand that has been washed is an essential material used in infrastructure development and construction projects of all sizes. Due to the depletion of natural sand sources in Qatar, there has arisen a need to develop ... -
Experimental Validation of Repair Methods for Earthquake-Damaged Bridges Incorporating Pipe-Socket Precast Pier System
( Qatar University Press , 2023 , Conference Paper)This project focuses on the retrofitting of concrete bridge piers. In the first phase of the project, a half-scale bridge bent was designed and experimentally tested in the Idaho State University (ISU) Structural Lab (SLAB) ... -
Potential Implementation of Warm Mix Asphalt (WMA) in Pavement Construction in the State of Qatar
( Qatar University Press , 2023 , Conference Paper)Warm-mix asphalt (WMA) technology has been used in many countries around the world, in lieu of Hot Mixed Asphalt (HMA), due to its ability to allow significant reduction in the temperatures at which asphalt mixes are ... -
Launching a 148m-Long Tunnel Boring Machine from a 15m-Inner Diameter Shaft
( Qatar University Press , 2023 , Conference Paper)The city of Doha has grown and expanded rapidly in the last 20 years, but this growth has strained the country's infrastructure, including its aging sewerage system and treatment facilities. ASHGHAL has therefore launched ... -
The Use of Demolished Concrete Lumps (DCL) in Rectangular CFSTs Under Flexure
( Qatar University Press , 2023 , Conference Paper)This paper investigates the flexural performance of rectangular concrete-filled steel tube (CFST) beams that are partially incorporated with demolished concrete lumps (DCLs). In total, three CFST beams were prepared and ... -
