دانلود کتاب ACI 126.3R-99: Guide to Recommended Format for Concrete in Materials Property Database (Reapproved 2008)

This guide presents recommended formats for concrete materials property data for entry into computerized databases. The purpose of this guide is to facilitate efficient storage and retrieval of information about concrete and its constituents with a computer and allow meaningful comparison of data from different sources. It is intended for use by those responsible for planning and maintaining a concrete materials property database as well as those who enter data. Recommended formats are provided for organizing and subdividing information about hydraulic cements, aggregates, chemical admixtures, mineral admixtures, fibers, water, concrete processing, and concrete properties and performance suitable for use in developing a computerized database. ACI committee 126 developed this guide to be consistent with the principles of ASTM Committee E-49, Computerization of Material and Chemical Property Data. Before computers can replace laboratory notebooks and published reports as a more efficient means for storing and retrieving concrete materials property data, recording standards are needed. The recommended formats in this guide are a first step toward fulfilling this need.
