About a month ago on 19th February, my materials & construction class had a hands-on lab where we were to make a batch of concrete that would be compression tested. The test was on the 17th of April.
Our mix consisted of:
- 40oz Cement
- 45oz Water
- 45oz Sand
- 40oz Aggregate
- 1ft² sheet of fiber glass cut up
- 1ft² sheet metal mesh cut up
- Concrete dye
- 65 paper clips
The design mix held 197,000 lbs!!
