Backfilling Shaft Surround Using Recycled Concrete Waste Material
( Qatar University Press , 2023 , Conference)The massive development in the State of Qatar to fulfil the Qatar National 2030 Vision requires efforts to direct the construction sector towards reducing economic, social and environmental impacts through the application ... -
Marine Dredging Sediments Valorization in Self-Compacting Concretes
( Qatar University Press , 2023 , Conference)Rock and eroded soil are transported by wind, tide, and human action (development works), and deposited as sediment in ports, estuaries, and rivers. The sediment accumulation at the bottom of ports disrupts maritime ... -
Utilisation of Waste Plastics Admix with Laterite Soil for Production of Road Pavement Interlocking Blocks
( Qatar University Press , 2023 , Conference)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 ... -
Impact of the Fiber Distribution Characteristics on the Uniaxial Behaviour of Fiber-Reinforced Composites- An Experimental Study
( Qatar University Press , 2023 , Conference)The demand for development of fiber-reinforced composites has enhanced as the practise of integrating fibres into concrete has become prevalent over the past few decades.. The intersection zone where the fiber crossing the ... -
Ashghal Quality Assurance & Quality Control system - QSD Role in Monitoring & Reporting the Quality Performance in Ashghal Projects

Utilization of Recycled Materials in Infrastructure Projects: Ashghal Approach
( Qatar University Press , 2023 , Conference)As a result of numerous infrastructure projects which have taken place in Qatar in the last decade, there has been an unprecedented increase in demand for construction materials. In addition, the huge program of infrastructure ... -
Launching a 148m-Long Tunnel Boring Machine from a 15m-Inner Diameter Shaft
( Qatar University Press , 2023 , Conference)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 ... -
Influence of Pier Stiffness on Track-Bridge Interaction
( Qatar University Press , 2023 , Conference)The bridge is a common engineering structure over which a rail track is often laid. With the introduction of continuous welded rail (CWR), major rail tracks have shifted worldwide from jointed rail to continuous welded ... -
The Use of Demolished Concrete Lumps (DCL) in Rectangular CFSTs Under Flexure
( Qatar University Press , 2023 , Conference)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 ... -
Modeling Short-Term Deflection of Reinforced Concrete Slabs using the Layered Approach
( Qatar University Press , 2023 , Conference)This paper examines the short-term deflection of reinforced concrete slabs taking the tension-stiffening phenomenon into account. The main goal of this study is to develop a model that predicts the deflection of one-way ... -
Recycled Polypropylene Fibres for Reinforcing Cement Mortar under Arid Conditions
( Qatar University Press , 2023 , Conference)Concreting in arid environment is a delicate operation, due to many problems, such as the premature evaporation of mixing water, which affects the material consistency and the shrinkage cracking which threatens its durability. ... -
Analysis of Factors Affecting the Performance of Dynamic Compaction Technique: A Study of Coastal Area of Eastern Province in Saudi Arabia
( Qatar University Press , 2023 , Conference)Coastal areas of the Eastern Province of Saudi Arabia have soil with low bearing capacity due to saturation with water, high contents of salt and inclusion of organic materials. The dynamic compaction (DC) technique, which ... -
