This book brings together expert knowledge from around world about different alternative binders, presenting case histories demonstrate successes pitfalls, practical based experience. recurring theme need work towards wider acceptance lime, by: establishing realistic performance cements getting these international, national codes standards. Establishing testing procedures measure compliance with standards; holding seminars training courses compiling study existing production use; and, initiating research projects nature.
