1. Objectives:-
Concrete is the most common and versatile construction material. Those who deal with concrete need to have “Hands on” experience and genuine feel of concrete making, to understand its quality and behavior. Concrete making with variations in characteristics of cement, proportioning of aggregates, chemistry of material and chemical admixtures, control of water-binder ratio is a challenge to any Civil Engineer. Through this event we see ahead to encourage young engineers, professional, contractors, etc. to experience through this competition, the art and science of producing good quality concrete.

 

2. The competition:-
Produce concrete to achieve, as closely as possible, a compressive strength of 15 MPa on the day of competition at the time of testing of the cubes. Other parameters of mix design may be chosen by the competitors to obtained the closest specified strength on the day of testing.

 

3. Eligibility:-
3.1) The competition is open to all the college students of any discipline.
3.2) A team of competitors shall consist of maximum two participants, also more than one team from same college can take part in the competition, but each team shall have different set of participants and Mix Design.
3.3) The completed “Data Sheet” must form a part of Mix Design Report duly certified by the Head of Department/ Faculty Member of that college.

 

4. Use of materials:-
4.1 Coarse and fine aggregate from natural source shall comply with requirements of IS-383. The maximum size of coarse aggregate, gravel, or crushed stones shall not exceed 20mm.
4.2 Cement shall be any of the following:-
a) Ordinary Portland Cement
b) Portland Slag Cement
c) Portland Pozzolana Cement
4.3 Chemical Admixtures to confirm to IS-9103 or ASTM 494 or 1017 as applicable, may be added.

 

5. Mix Design:-
The mix shall be designed to achieve strength of 15 MPa on 7 days water cured cube sample testing.

 

6. Cube Specimen:-
Cubical test specimens shall be of 150X150X150 mm in size within a tolerance limit of 3mm, cast as monolithic one unit. Any reinforcing by provision of bars, fibres  or mesh, impregnation with materials like any polymer, epoxy or any synthetic glues or similar binders or modifiers is not permissible.

 

7. Curing and age of Cubes:-
7.1) Minimum 7 days curing should be done in clean fresh water at ambient temperature.

 

8. Submission of the entry:-
8.1) A Mix Design Report shall be submitted with each entry is not more than 12 pages in A4 size papers with 1½ space typing.
8.2) Minimum 3 cubes shall be submitted with each entry.
8.3) Mark ‘X’ from corner of the upward face of the cube to receive the test load.
8.4) Name of the participants/institutes shall not be indicated or marked on the cubes.

 

9. Testing of cubes:-
9.1) Testing of cubes will start at 10.00am on 5th March 2008, at “Concrete Testing Lab”, Department of Civil Engineering, Sinhgad College of Engineering, Pune-41.
9.2) The average strength of 3 cubes in direct compression shall be considered for merit adjusted from following:-
a) Ratio of strength to cement content
b) Uniformity of results
c) Deviation from target strength
d) Economy

 

10. Adjustments:-
a) The institute will appoint the judges.
b) Decision of the judges regarding acceptability of cubes for entry and evaluation of the merit shall be final.
