This Standard sets out the method for determining the lime or cement content of samples of soils, gravel or crushed rock stabilized with lime or cement either in a cured or uncured state by titrating with ethylene diamine tetra-acetic acid disodium salt (EDTA) to determine the soluble calcium ion content (Ca2+). The method is dependent on determining the amount of calcium ions in the stabilized material, the lime or cement additive and the unstabilized material on a dry basis.
