Non-destructive Evaluation of Cementitious Materials using Highly Nonlinear Solitary Waves
This project is to develop a novel non-destructive evaluation (NDE) technique for accurate assessment of the strength of cementitious materials and detection of defects in cementitious materials. The NDE technique will use highly nonlinear solitary waves (HNSWs) generated in a granular crystal sensor. The dynamic interaction of HNSWs in a granular crystal sensor with cementitious materials is studied to evaluate their mechanical properties such as the compressive strength and the elastic modulus of fresh and hardened cementitious materials and the effect of micro/nano reinforcements on strength. Moreover, we explore the possibility of the detection of defects such as voids or cracks in cementitious materials using a granular crystal sensor.
Thermo-Mechanical Tire-Pavement Interaction
This project is to reduce high level of traffic accident fatalities in Abu Dhabi by studying skid resistance of an asphalt pavement influencing rod driving safety. To achieve this goal, this research focuses on developing reliable experimental and computational techniques to account for the influence of asphalt pavement temperature on skid resistance measurements in UAE. This will be achieved on the basis of laboratory tests, field tests, and advanced computational techniques. The particular advantage of this approach is that for any given pavement surface the influence of environmental and operating conditions on skid resistance can be evaluated and quantified.
Mechanical Properties and Durability of Cementitious Materials with Micro/Nano Reinforcements
This research is to investigate the effects of micro/nano reinforcements (e.g., carbon nanotube and graphene) on the mechanical properties and durability of cementitious materials (e.g., concrete and mortar) to extend the service life of the civil structures. Experiments are performed to verify the performance of micro/nano reinforcements to produce high-quality concrete/mortar that can improve poor ductility and resistance to cracking of traditional concrete. This goal will be achieved by evaluating the compressive strength and flexural strength of cementitious materials with the addition of reinforcements and determining the optimal quantity of reinforcements that can produce high values of strength properties based on the parametric study of mix proportions. Moreover, the effect of micro/nano reinforcements on chloride ion penetration into cementitious materials will be investigated under UAE environmental conditions.
Effect of Micro/Nano Reinforcements on Mechanical Properties of 3D Printed Cementitious Materials
This project will explore the development of cementitious-based 3D printable materials toward a goal to the design of new additively manufacturing for concrete infrastructure construction. Of particular interest of this research is the design of a cementite-based 3D printable material, with/without micro/nano-filaments, that has good mechanical properties, least sensitive to running conditions and curing quickly, and that can build small- and large-scale structures in UAE extreme environmental conditions via the 3D printing process. This research will be achieved as follows: 1) Development and testing of a 3D printed cementitious material with micro/nano-filaments for additive manufacturing; 2) 3D printing of small- and large-scale structures using a cable driven 3D structure printer; 3) Quantification of the printed structures from dimensional and strength points of view.
