QUIKRETE® Fiber-Reinforced Concrete Mix #l006-60Properties
Mix meets or exceeds the strength requirements of ASTM C387. It will achieve a compressive strength of 2500 psi (17.3 MPa) at 7 days and 4000 psi (27.6 MPa) at 28 days when tested in accordance with applicable standards.

Constituents and Nomenclature
This is the apparatus that we used to test our concrete samples
for our compression analysis
Our “ideal” water concentration samples should have theoretically had the greatest compression, but since they
did not, we should have added more water (such as 15% more) or until visually satisfying. Therefore giving the
“ideal” concentration the highest compression and the 15% more and 15% less, a lower compression result.
Some of our samples had so little water that they just crumbled under compression and gave no data reading.
