Methods for testing lime in the field Humanitarian Library

The British Standard Specification for Building Limes (BS 890: 1995) does not specify the CaO as ‘available lime’. Instead, chemical quality is based mainly on the overall CaO + MgO and the CO 2 content. So, for instance, for Calcium Lime 90 (CL 90) equivalent to ‘high-calcium lime’, the chemical specification is: CaO+MgO MgO CO 2 SO 3
