Jafar Al Rashid

Create a prototype system to track concrete specimen

Use consumer level mobile devices

Integrate with Qest Field

Aim
Concrete is a major component in construction projects

Often tested in high volumes

Manual identification
Background
Wet concrete
sample
taken in field
Field tests are
carried out &
recorded
Specimens made
in the field from
wet samples
Specimens left
on site to cure
Field test
results returned
to office
Specimens retrieved from field
Specimens
logged in
laboratory
Specimens
weighted and measured
Specimens compressed & results recorded
Compressive strength data reported
Field test
results
reported
Specimens tied to field results
Phase 1 Attachment methods
Phase 2 Reliability
Phase 3 Statistical Evaluation
Tested 3 methods
1) Throw NFC tag inside the mold first
2) Pure a little bit of concrete first
3) Create the cylinder first and then push the NFC tag inside
Non of the tags is waterproof
Used 6 cylinders, 12 NFC tags
6 at the top and 6 at the bottom of each cylinder
3 for method 1
3 for method 2
6 for method 3

Needed to test the attachment method

Both waterproof and normal tags used

16 cylinders created, 1 tag in each

Kept in a curing tag and checked every week

Developed android application for the read rate of the tags
Used to phones to obtain better results
