Project Description:

Ultra High Performance Concrete contains as an essential component mass reinforcement in the form of fine short fibers, either made of steel or other synthetic materials. The strength of the final product depends to a great extent on the tensile strength of the fiber – however fiber manufacturers provide the nominal technical data of the fibers (strength in tension and elongation capacity) whereas UHPC manufacturers have no means of assessing the actual strength. Fiber elements are less than 15mm long and their diameter may be tenths of a mm. To carry out a direct tension test on these products it is necessary to use electronic microactuators and micro-load cells, miniature grips and proper data collection and data acquisition procedures. No such facility is available at the moment for the testing needs of the industry. The summer project will involve fabrication, verification and proofing of prototype test beds that could serve the purpose of testing quickly small samples of fiber for strength assessment and deformation capacity estimation.

Duties and Responsibilities of the student:

Work together with graduate/doctoral student towards the development of a miniature test bed for assessing the strength of steel fibers. If successful the product could be possibly patented.

Skills and Qualifications:

(Technical Skills): Dexterity with electronic equipment, and understanding of basic mechanics of materials

(Interpersonal Skills): Good at team work

(Assets): Interest in Structural Engineering

Degrees, courses and Disciplines prerequisite*: Civil Engineering Third or Fourth Year

Stipend: TBD

External applicants can apply? N/A

Duration: 16 weeks minimum

Start Date: 05/01/2018 (estimated)

End Date: 08/31/2018 (estimated)
