MCI-2005 and MCI-2006 Beats DCI in ASTM: G109 Testing

 

MCI¨ competitor DCI (calcium nitrite) has begun to corrode in an ongoing ASTM: G109 test between Cortec¨ MCI-2005, MCI-2006 and other competitors. At a dosage of four gallons per yard, the intital corrosion rate of DCI is 20 percent greater than the initial rate of the control. American Engineering Testing, St. Paul, Minnesota, found the DCI samples started to corrode in the forty-third test cycle. They are expected to surpass the MCI-2006 samples for the total charge passed in the sixty-second cycle of testing.

The ASTM: G109 test is a standard test that determines the effects of chemical admixtures on steel reinforcements embedded in concrete in chloride environments. Each cycle runs about a month, with two weeks wet and two weeks dry. See the enclosed report for detailed information.
