COMPOSITION AND PROPERTIES OF LIME. 117 



Limes of this type slake rapidly when water is added and develop 

 much heat during slaking. They also expand notably, so that the 

 resulting paste (slaked lime) will be much more bulky than the original 

 lime. 



Lean or poor limes. A lime containing over 5 per cent of such 

 impurities as silica, alumina, and iron oxide will usually be dark in color, 

 comparatively slow slaking, and difficult to trowel in working. Such 

 limes are known as " lean " or " poor " limes. In a few cases the impuri- 

 ties are so evenly and finely distributed throughout the original lime- 

 stone that on burning the limestone a certain amount of combination 

 takes place between the lime (CaO) and the impurities. This gives 

 slightly hydraulic properties to the product. Ordinarily, however, 

 no such chemical combination takes place on burning, and the impuri- 

 ties simply serve to depreciate the quality of the lime produced. 



The following analyses (Table 39) are of lean limes produced at 

 various localities in the United States.
