X1. SLAKING AND PREPARATION OF LIME PUTTY
X1.1 Introduction
X1.1.1 Quicklime can never be used as such for structural purposes; it must always be slaked first. Since the method of slaking
is an important factor in determining the quality of the finished product, the following directions for the preparation of lime putty
are given, not as a part of the specification, but as information for the further protection of the purchaser.
X1.1.2 Different kinds of lime vary considerably in the way in which they behave with water. A little supervision over the
operation of slaking will amply pay for itself by ensuring the production of the greatest possible quantity and the best possible
quality of putty. To find out how to slake a new lot of lime, it is safest to try a little of it and see how it works. Since different
lots of the same brand of lime vary somewhat, and since the wea
