Aggregate and Polymer testing
We got the biodegradable polymer from Coim Inc. and have begun to test various ratios of sand aggregate to polymer. Our early hypothesis that a 60:40 sand to polymer ratio would be the most effective seems to be in error. We have begun testing ratios between 80:20 , 85:15, and 90:10 . Having made a couple TEST MUFFINS, we are letting them completely set. A piece was placed in water to begin to observe the degradation time. 3 mixes and 25 pairs of vinyl gloves gone.
