Mortar Master

Bored of using the same materials in concrete? Bored of the routine theory sessions in concrete? Want to do something practical? Here is a chance for you to try out new stuff and come out with a concrete cube of the given specifications.

Abstract Deadline Extended to 14th February 2019

Upload Abstract

The event consists of two stages(note: not two rounds). The first stage will include activities that you will be carrying out at your respective colleges and the second stage will be conducted at NIT-Trichy.

Stage 1:

  1. Registration for the event

  2. Release of the problem statement

  3. Designing the mix and casting three concrete blocks within the specified restrictions.

  4. Preparing a report of the design mix and its online submission to us before the specified deadline

Stage 2:

  1. Bring the cast concrete blocks to our college during Pragyan.

  2. Weight, strength and size of the blocks will be tested.

  3. The submitted design reports will be evaluated and the teams will be asked to give a brief oral presentation of their work upon which they will be questioned.

  4. Points would be awarded across each category (See Judging Criteria) and the winner will be adjudged accordingly.

Note:The resources for accelerated curing have been uploaded in the website and can be used by the participants for reference. Shortlisted candidates will be informed via e-mail.

 

Rules:

  • 2 to 3 members per team.

  • The mix design should strictly adhere to the Indian Standards Code.

  • It is necessary to get the design report attested by the Head of the Department of your college.

  • Design mix report should be uploaded in the site on or before 14th February 2019.

  • The abstract should be in the standard format as mentioned in the resources.

  • Any violation or deviation from the criteria mentioned in the problem statement will result in the disqualification of the team.

  • Any violation from the rules mentioned will also lead to the disqualification of the team.

  • The judges’ decision will remain final.

 

Judging Criteria:

The contestants will be judged on the following points:

  • Least weight:

The least average weight among the contestants will be adopted as the datum, say D kg. Teams with average weight of their cubes falling within D kg and (D + 5% of D) kg will proceed for the oral round. In case the number of teams falling within this range is low, then the top five teams with the lowest average weights will proceed for the oral round.

The next section concerns only those teams that qualify for the oral round.
Points awarded for the least weight will be equal to (2.5 – w)*25, ‘w’ being the average weight of the three cubes in kg.
Note: Only teams scoring positive points in this will proceed to the next stage. For example if average weight of the cubes turn out to be 2.6 kg then points awarded will be
= (2.5-2.6)*25= -2.5, in which case the contestants automatically fail to qualify, even if the team finishes in the top five.

  • Design report:

The design report to be submitted online will carry 10 marks and will be awarded by the judge. Contestants are advised to stick with the design format provided in the Pragyan website.

  •  Oral briefing:

The oral presentation will be conducted by the judge, who will also question the team members on the submitted design report. This section will carry a total of 20 marks.

Design three concrete cubes of 100 mm size having strength of 40-48Mpa. Take note that the range is not for the average strength of the three cubes but calls for each cube’s strength to fall within the specified range. Within the specified range there are no points awarded for higher strength. Least weight of the concrete cubes is desirable and their average will be taken for grading in the judging format.

Abstract Submission Deadline:  14th February 2019.
