Project Concrete Quality Assurance System Program (PCQAS)

PCQAS is a menu-driven database program designed to store concrete test data, materials physical properties, and source data. It then assembles the data to produce user-defined reports, tables and graphs. The program also compiles the fresh concrete and aggregate test results to determine yield quantities per cubic yard. Based on these data, PCQAS can make adjustments to the concrete mixture proportions. Reclamation designed the program to accomodate either its own or ASTM's (American Society for Testing and Materials) test methods and specifications, and to work in SI metric or inch-pound units.

Installation instructions (for Windows-based systems):

  1. Download the zip file pcqas.zip.
  2. Extract the contents
  3. "Open" or "run" the installation file cinstall.exe. Follow the prompts.
  4. Once installation has completed, use the Windows Explorer to locate the file CONFIG.NT in the folder C:\Windows\system32, but note the following cautions:
    1. This file may be hidden, so in order to see it, you may have to click on Tools → Folder Options → View and then check the option "Show hidden files and folders" and uncheck the option "Hide protected operating system files."
    2. Users running Windows 98 or earlier versions will not have this file and should instead make changes to CONFIG.SYS, located in the root directory (usually C:\).
  5. Double-click on the CONFIG.NT file, to open it in Notepad.
  6. Look for the line "files=nn" (where nn is a two-digit number) — usually near the end of the file — and change the number to 85.
  7. If you don't find any such line in the file, add "files=85" (without quote marks) at the end of the file.
  8. Save and close the file.
  9. Reboot your system. Then you should be ready to run PCQAS!
