The most common raw material for making lime is limestone, which is one of the world's most abundant minerals, widely available in many countries. Lime has many other uses, but this book is specifically about its use in building and construction, for which it has a proven track record through several millennia. Despite this long and successful history, in recent times it has been largely neglected whilst ordinary Portland cement has dominated the market. Building with Lime seeks to rectify this situation. The book is a revised, updated and improved edition of the very successful one of the same title, by the same authors, published by the same organization in 1997. This book is intended as a starting point for those considering lime as a building material, and as a general reference to the broad range of uses for lime in construction. It shows how to make the best use of different types of lime, whether extracted locally or transported from further afield. The book provides information that will assist manufacturers, policy-makers, investors, suppliers, and the builders and owners or users of the buildings themselves to understand the value of lime.
