Abstract
A simple and rapid method of determining chloride in portland cement concrete powder is described. This method can be used under field conditions in a portable laboratory. An organic flocculant is used to flocculate the insoluble portion from a portland cement concrete powder suspension in hot water. The clear decant is analyzed for chloride content using a chloride ion-selective electrode.
