Title: COMPUTER-AIDED DESIGN OF PORTLAND CEMENT CONCRETE MIXES
Accession Number: 00474230
Record Type: Component
Availability: Find a library where document is available Abstract: A prototype or first version of a software package being developed to assist in portland cement concrete mix design is described. This is not necessarily a research project but rather a research tool in which design information from various sources has been gathered into a single algorithm and organized into a usable and versatile form. The program consists of three sections: design of the first trial batch by any of the five commonly used methods, adjustment of an unsuccessful trial batch by a combination of empirical routines and those derived from American Concrete Institute methods, and a data file of various types of mix design information. This last section may be used independently or as an aide in blending or adjusting a mix. User friendliness is a key element of this algorithm. Computer-user interaction occurs throughout and is especially useful for the inexperienced designer. Designed and written initially for mainframe computers, the program features the addition of a translator for a problem-oriented language (SCAN), which leads to greater freedom from the structured input environment. Currently the software is being downloaded to a microcomputer (MS-DOS) system. Program output includes batch weights of the usual concrete ingredients as well as weights per cubic yard. Additional parameters provided include batch size, percent air, cement factor, unit weight, and water-cement ratio. A plot of unit weight versus air content is also offered. Like much software, this package is continually being modified and developed; however, it has already demonstrated its usefulness as a computer-aided design system.
