Winners will be selected based on submissions meeting the (Objective)

Saturday, February 8th (Casting)

Arab Center for Engineering Studies (ACES)

Saturday, March 7th (Testing)

Arab Center for Engineering Studies (ACES)


1. To produce concrete cubes with an average compressive strength of (50 MPa) and a saturated surface-        dry density of about (2400 kg/m3) with the highest cementitious efficiency and the lowest cost. To prepare      and submit a report as per section 7 of this competition. (100 points)

2. To prepare and present a Flash Poster (within 1 min.) explaining the process of designing, preparing,             testing the cubes & outlining the main findings. One example of a Flash Poster presentation can be                 found at (20 points)


Students winning the First prize will receive a cash prize of 450 JD. Second and Third prizes will receive 360 JD and 240 JD, respectively. All winners will also be awarded certificates of recognition.


1. Design and prepare concrete mix.

2. Use cement economically! Cost is a factor in the competition.

3. Use and test 3 concrete cubes (cube side: 150 mm).

4. (Final) concrete mix to be supervised in the Concrete Lab. at ACES.

5. Curing:

a. Cubes to be tested must be standard laboratory moist cured, provided that the cubes do not leave ACES.     

b. Cubes must be at or near room temperature at the time of testing.

c. No external loads may be applied during curing (including pressure).

d. (Trial) mixes and cubes may be prepared and tested at any concrete lab. Not necessarily at ACES. Preferably at Students’ universities. This may include mixing & preparing 3 cubes, and testing them at 7days.

e. Final mixes and cubes must be prepared and tested at ACES.

6. Laboratory materials allowed: Type I portland cement, silica fume, crushed limestone, natural aggregate, natural sand, superplasticizer, calcium chloride, set retarder.

7. Any other materials will NOT be allowed including those below:

a. Steel or metallic aggregate or reinforcement.

b. Fibers of any size.

8. Cubes will be tested at (28 days). The average compressive strength of (three) cubes will be calculated.


1. Participants must be undergraduate civil engineering students currently enrolled at university. 

2. Teams of up to three students (maximum) may participate. A student may not be a member of more than        one team.

3. Each team may submit one entry only.

4. Students have to register their team and testing plan with the competition (Tehcnical Manager) before             they are given clearance to start work in the lab.


The strength and density will be scored for how close the measured values are to the specified values. The cost will be the sum of the costs of the individual materials, priced at contest assigned costs (to be provided). The cement efficiency will be the compressive strength divided by the total amount of cementitious material in one cubic meter of mix for a result in MPa/#cement per cubic meter. The report and flash poster, each, will be given scores of 5 (excellent), 4 (very good), 3 (good), 2 (fair) or 1 (poor). The following formula will be utilized to compute the score, out of 120, of (items 1 and 2) in the (Objective):

Score120= (20-2.5|∆fcu|)+(20-0.25|∆D|)+(20-2|∆S|)+(20-400|∆Eff|)+4RS+4FPS


∆fcu= fcu - 50 MPa; fcu is the measured average compressive strength of three cubes.

         |∆fcu| is limited to 8 MPa

D = D - 2400 kg / m3; D is the measured average density of three cubes.

             |∆D| is limited to 80 kg m3

S is the deviation from the lowest cost design.

             |∆s| is limited to 10 JD

Eff is the deviation from the most efficient design; efficiency = fc  ⁄  kg cement per cubic meter.

           |∆Eff| is limited to 0.04 MPa / kg

RS is report score; 5 (excellent), 4 (very good), 3 (good), 2 (fair), 1 (poor), 0 (none)

FPs is flash poster score; 5 (excellent), 4 (very good), 3 (good), 2 (fair), 1 (poor), 0 (none)


1. Two (student judges) and one (senior council) will be appointed by the student  competition committee.

2. The judges will determine whether or not the rules have been followed.

3. The decision of the judges will be final, and no appeals are allowed. The council will moderate the opinion of the       judges, if the need arises.

4. The judges may, if needed, use any means to verify the requirements of the competition.

5. The student competition committee retains the right to modify these rules as special circumstances arise.


The Official Mix Design and Testing Forms along with the written report must be emailed to

[email protected] by March 10, 2020.

The (Report) must be sent as a (Microsoft Word) document and the (Mix Design and Testing Forms) must be sent as (Microsoft Excel) spreadsheets. Formats other than Word and Excel will not be accepted. Failure to meet this deadline will result in a score of zero for the report. These forms are used in scoring the competition. They must be correct and are subject to verification. (Hard copies) of The Official Mix Design and Testing Forms & written Report must be submitted (in person) on the (Day of Testing the cubes).

A (Flash poster) as per the requirements of item 1 (Objective) shall also be emailed to [email protected] by March 17, 2020.

All Civil Engineering Students are invited!
