Longterm Field And Laboratory Leaching Tests Of Cemented

Mar 15, 2011 High leach rates were found for sodium and nitrate at the initial stages of the laboratory leaching test. Nearly half of the initial nitrate salt content dissolved during the 1-year leach test. The release of sodium nitrate has led to about 10 increase in porosity and to a decrease in mechanical strength to lower values.
