About the position

We have a vacancy for a PhD Candidate at the Department of Structural Engineering

The vacant PhD position is on production and durability of sprayed concrete tunnel linings in a new research project: SUPERCON - Sprayed sUstainable PErmanent Robotmade CONcrete tunnel linings. The research partners are SINTEF (project leader), NTNU, NGI. The Norwegian research council and a group of industries fund the project. The main objective of the PhD is to investigate durable and functional sprayed concrete materials with low environmental impact for permanent and water proof tunnel linings. The production process (materials selection, proportioning, pumping, spraying, curing) is important for the quality of the lining. Therefore, input data affecting the sprayed lining quality will be investigated. This includes rock contour scans, concrete rheology- and set-properties, pump-and spray velocity and pressure, layer build-up, compaction, rebound etc. To make spraying robots more autonomous, real-time monitoring of such parameters may also be needed as input- and control parameters to predict and obtain required lining quality. In addition selected in-situ hardened lining properties will be investigated, for example compaction, porosity, strength, shrinkage, permeability and frost durability. Some of this work will be done in separate parts of the SUPERCON project. Hence the PhD candidate will interact in both study of the robotic application and of finished lining quality.

For the PhD position we seek civil engineering candidates with background in concrete materials and/or structures, civil production and/or engineering geology. The candidate must have an interest in / be open to combine research on properties of fresh (rheology, proportioning, sprayability) and hardened (strength, durability) concrete with robotics. The research shall increase the understanding of fresh and hardened properties of sprayed low-carbon concrete adapted to an operator-free spraying process. The candidate will work with a team of experienced researchers within the fields of concrete materials, civil production, tunnelling and engineering geology as well as two companies manufacturing robots and -control systems. The PhD will also cooperate with an ongoing PhD study at NTNU IBM on durability and life-time of tunnel linings.

The position reports to professor Stefan Jacobsen.

Job abstractJV_description

• review and course work
• investigate material- and process parameters affecting sprayed concrete performance

Qualification requirements

PhD candidate:
The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master's degree or second degree (equivalent to 120 credits) with a strong academic background in concrete materials or equivalent education with a grade of B or better in terms of NTNU's grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant

Other qualifications

• MSc of civil engineering within concrete technology, candidates with some course- and project specialization within concrete technology and-/or cement based materials. Candidates with MSC degree in other fields (eg. concrete structures , heavy construction- or tunnelling production, engineering geology, or similar) may also be considered
• Interest in combining well-structured experimental-/ laboratory research with research hypotheses and models
• computer science/ -process control
• Excellent written and oral English language skills. Norwegian language skills is an advantage

Personal characteristics

• highly ambitious and motivated for research work in this field
• keen interest in experimental and practical engineering research work in the laboratory
• well-organized and able to plan and conduct laboratory activities and execute experiments
• team worker that can cooperate in interdisciplinary team

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement

We offer

• exciting and stimulating tasks in a strong international academic environment
• an open and inclusive work environment with dedicated colleagues
• favourable terms in the Norwegian Public Service Pension Fund
• employee benefits

Salary and conditions

PhD candidate:
PhD candidates are remunerated in code 1017, and are normally remunerated at gross from NOK 449 400 before tax per year. From the salary, 2 % is deducted as a contribution to the Norwegian Public Service Pension Fund.

The period of employment is 3 years (or 4 with 25% required duties). Appointment to a PhD position requires admission to the PhD programme in Engineering.

As a PhD candidate, you undertake to participate in an organized PhD programme during the employment period. A condition of appointment is that you are in fact qualified for admission to the PhD programme within three months.

Appointment takes place on the terms that apply to State employees at any time, and after the appointment you must assume that there may be changes in the area of work.
