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 ...
Marine Dredging Sediments Valorization in Self-Compacting Concretes
(
Qatar University Press
, 2023 , Conference Paper)
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 ...
Impact of the Fiber Distribution Characteristics on the Uniaxial Behaviour of Fiber-Reinforced Composites- An Experimental Study
(
Qatar University Press
, 2023 , Conference Paper)
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 ...
Planning and Implementing of Effective Enabling Works for a Successful TBM Tunnelling Project
(
Qatar University Press
, 2023 , Conference Paper)
The outfall tunnel, which forms part of the Musaimer Pump Station and Outfall project (MPSO), is a 10.2 km long subsea tunnel that extends from the south coast of Doha, starting onshore, and continues under the Arabian ...
Influence of Pier Stiffness on Track-Bridge Interaction
(
Qatar University Press
, 2023 , Conference Paper)
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 ...
Backfilling Shaft Surround Using Recycled Concrete Waste Material
(
Qatar University Press
, 2023 , Conference Paper)
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 ...
Characterisation of Sewage Sludge and Municipal Solid Waste for Use as Cementitious Materials
(
Qatar University Press
, 2023 , Conference Paper)
Volumes of accumulated solid waste materials of sewage sludge (SS) and municipal solid waste (MSW) in Qatar continue to increase annually with a potentially negative impact on the environment. This paper presents an ...
Utilization of Recycled Materials in Infrastructure Projects: Ashghal Approach
(
Qatar University Press
, 2023 , Conference Paper)
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 ...
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 ...
Effect of Chemicals on Compressive Strength of Plastic-Laterite Interlock Paving Blocks
(
Qatar University Press
, 2023 , Conference Paper)
This research centres on the need to develop a simple but sustainable material for the utilization of the quantum of plastic wastes that litter our environment. The research uses waste plastics and laterite soil and converts ...
