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 ... -
Performance of Mild Steel and Corrosion-Resistant Steel Rebars in Chloride-Contaminated Concrete
( Qatar University Press , 2023 , Conference Paper)Reinforced concrete (RC) infrastructure in Arabian Peninsula is subjected to harsh climatic conditions of high temperatures, humidity, and airborne chlorides and there is a high concentration of salts in seawater and soils. ... -
Upgrading Existing Infrastructures - The Case Study of Industrial IC Bridge
( Qatar University Press , 2023 , Conference Paper)Doha, the capital of Qatar, has been facing phenomenal growth of vehicular traffic owing to rapid development which has resulted in traffic congestion causing significant rise in travelling time in some areas. To mitigate ... -
Galvanized Steel as a Sustainable Material-Technology and Failure Analysis
( Qatar University Press , 2023 , Conference Paper)The building industry is responsible for 40% of global CO2 emissions and 36% of global energy consumption. Therefore, it is not surprising that the industry is motivated to embrace more environment-friendly procedures and ... -
Data Interpretation Framework for Pile Thermal Integrity Testing
( Qatar University Press , 2023 , Conference Paper)Given the inherent nature of how deep cast in-situ concrete foundations (piles and diaphragm walls) are constructed, evaluating their integrity is difficult. Several well-established methods for testing integrity have been ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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) ... -
Utilisation of Waste Plastics Admix with Laterite Soil for Production of Road Pavement Interlocking Blocks
( Qatar University Press , 2023 , Conference Paper)Plastic wastes are non-biodegradable and hence pile up in refuse dumps and streets constituting an eyesore and menace to the environment. Some of them end up in drainages and waterways where they block water passages ... -
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 ... -
