Development and Performance of Cement Bound Materials in Road Pavements
( Qatar Univesrity Press , 2020 , Conference Paper)The use of cement bound materials (CBMs) for road construction in Qatar is relatively new. CBM improves the structural capacity and durability of pavement, but considerations should be made to the setting time and strength ... -
Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
( Qatar Univesrity Press , 2020 , Conference Paper)"Concrete is the most commonly used materials for construction in Qatar as well as in the world. Exposure to sever environmental conditions causes physical deterioration of concrete structures and significantly affect ... -
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 ... -
Effect of self-healing calcium nitrate microcapsules on concrete properties
( National Research Council , 2016 , Article)Self-healing concrete with microencapsulated calcium nitrate was investigated. The compressive strength of concrete admixed with microcapsules (as a percentage of the weight of the cement) was tested and compared with that ... -
Experimental prediction of the elastic properties of nanocomposite cementitious materials based on nanoindentation measurements
( American Scientific Publishers , 2017 , Article)This paper provides in depth novel exploration of the local mechanical properties of nanocomposite cement using the nanoindentation technique. The elastic properties of carbon nanotubes (CNTs)-reinforced and unreinforced ... -
Hardened Properties of Self-Compacting Concrete Incorporating Recycled Granite Waste as Fine Aggregate
( Qatar University Press , 2023 , Conference Paper)The present paper investigates the hardened properties of self-compacting concrete by reusing granite waste to replace natural fin aggregates. The reuse of solid wastes as powder or aggregates allows us to produce sustainable ... -
Mechanical Performance and Thermo-Physical Properties of Cement Mortar Incorporating Hybrid Slags
( Qatar Univesrity Press , 2020 , Conference Paper)Owing to the growing environmental pressure to reduce waste and pollution, the effective utilization of industrial solid wastes in construction applications has gained notable attention. This study investigates the mechanical ... -
