Specifications of concrete cube
1. The dimensions of the concrete cube should be 100mm.
2. The concrete cube must be solid and homogenous.
3. The concrete cube must have the same concrete mix design as the concrete bowlingball.
4. The concrete cube should be casted concrete and without any coating on it.
1. Each team's concrete bowling ball and cube must meet all requirements.
2. Only one concrete bowling ball and cube are allowed during the competition.
3. The concrete bowling ball must be presented during the registration.
4. The concrete cube is used to deter and check for verification purposes.
5. In the event of any false declaration of information by participants, the organizing committee reserves the final decision right to withdraw the participation of the teams.
3.1 Materials to be used

reason for the material used in concrete mix design should be provided.
4.0 Scoring Criteria
1. The competition scoring criteria are divided into four (4) parts: 10-pin bowling score,
strength to weight ratio test, workmanship and presentation.
2. Bowling balls which didn't pass the diameter and weight measurements will be
disqualified.
3. The entry requirement will be verified by the committee members.
4.1 10-Pin Bowling Score (20%)
1. The bowling ball will be placed on the ramp of the bowling track and released to knock
down the pins.
2. There will be two (2) bowling tracks of different lengths (long and short pathways)
and each team is given five (5) attempts equally distributed among members to knock
down the pins at each bowling track.
3. The final score will be calculated based on the sum of the three best attempts.
4.2 Strength To Weight Ratio Test (40%)
1. The participants are required to find a good balance between strength and weight within
the required limits to acquire the highest mark.
2. The concrete bowling ball will be tested using a compression testing machine.
3. The maximum load after failure will be recorded.
4. The score obtained will be calculated based on ratio:
4.1 The strength to weight ratio of the concrete ball for each team = k.
4.2 The value of k will be compared with the rest of the teams.
𝑇ℎ𝑒 𝑣𝑎𝑙𝑢𝑒 𝑜𝑓 𝐾 𝑓𝑜𝑟 𝑒𝑎𝑐ℎ 𝑡𝑒𝑎𝑚
𝑇ℎ𝑒 ℎ𝑖𝑔ℎ𝑒𝑠𝑡 𝑣𝑎𝑙𝑢𝑒 𝑜𝑓 𝐾 𝑎𝑚𝑜𝑛𝑔 𝑡ℎ𝑒 𝑡𝑒𝑎𝑚
𝑥40% = 𝑥𝑥%
