Packaged, dry, combined materials for mortar and concrete are combinations of cementing materials and aggregates which require only mixing with proper quantities of water to be ready for use. The packages, varying in mass from 5 to 41 kg (10 to 90 lb) generally are available at the producing plant, building supply, and hardware stores, as well as some supermarkets. The general trend is to mix the various ingredients thoroughly before packaging in moisture-resistant multiwall paper bags. Some products introduce the ingredients into the package separately without prior mixture. Still others package the cement separate from the aggregates. Since the original publication of ASTM Specification for Packaged, Dry, Combined Materials for Mortar and Concrete (C 387) in 1956 and during subsequent revisions of that specification covering these materials which will be discussed later in this paper, the buying public has become increasingly specification conscious.
