Introduction
The Materials Laboratory of the Civil Engineering Department is constructed over an enclosed area of 1000 square meter. It is fully equipped and supported by highly qualified technical staff to respond to the needs of academic institutions, researchers, engineers and construction industries for testing of:
(a) Concrete
(b) Cement
(c) Aggregates
(d) Natural Building Stone
(e) Tiles and Bricks Equipment
Latest state of the art equipments that are mostly fitted with computerized data collection are used to perform various types of materials testing to the highest standard. Some of these machines are:
1. Abrasion machines
2. BS & ACI Sieves
3. Flakiness & Elongation Gauges
4. Blain & Vicat apparatus
5. Concrete gradient analyzer
6. Concrete mixer
7. Compacting & Kelly Ball apparatus
8. Slump and V-B time apparatus
9. Concrete Permeability System
10. Flexural (beams) frame
11. Fully automated compression machine
12. ISAT
13. Bond Tester
14. Micro-cover meter
15. Universal Testing Machine
16. Corrosion mapping System
17. Concrete test hammer
18. Ultrasonic concrete test
All tests are run by highly qualified engineers and technicians who are constantly supervised by experienced faculties in order to assure the compliance of these tests with international standards (BS, ASTM, or EN). Accurateness of computer generated tests results are often verified and thus considered reliable by decision-makers. Quality assurance of material testing services is maintained through periodic evaluation programs in term of checking the calibration of the equipment and upgrading them to meet the market demands.
