CDIO Process for developing unfired brick---step 1

1st, accomplished reference reading and comprehending

2nd, selected raw materials and designed mixture based on the principles of environmental protection and energy-saving.

3rd, applied the first mixture and found that the w/c ratio was high, leading to lower strengths, as shown in Fig.1.

After reform

1st mix design

CDIO Process for developing unfired brick---step 2

1st, a further reference reading, team discussion and teachers` suggestions---to modified their mixture

2cd, selected raw materials according to the modified mixture.

3rd, applied the second mixture.

After reform

2nd mix design

Polymer was added, the w/c ratio was reduced

Comments from students

The teamwork re-design project of CEM makes us really go into the construction practice.

We resisted at first doing this project because we thought the experiment being hard, dirty and tired.

However, during the project process we really felt the joy of the harvest of working hard, and understood the knowledge more deep-set through learning from practice.

Here, I show my thanks to Teacher Li for providing us the good guidance, and I also thank my classmates for their good ideas to amend my project.
