ASTM C207 – Standard Specification for Hydrated Lime for Masonry Purposes
This specification covers four types of hydrated lime.
Types N and S are suitable for use in mortar, in scratch and brown coats of cement plaster, for stucco, and for addition to portland-cement concrete.
Types NA and SA are air-entrained hydrated limes that are suitable for use in any of the above uses where the inherent properties of lime and air-entrainment are desired.
