This program is a companion to our Quality Control-Concrete database software. QC-Statistics produces a complete mix performance document featuring statistical reports following ACI standards for minimum required average strength determination. Use on major projects to track mix compliance and performance and for identifying cost inefficiencies.

Mix Performance Analysis

QC-Statistics gives you a Mix Performance analysis which includes:

  • The minimum required average strength per ACI 301-10 section 4.2.3.3.a
  • Laboratory testing proficiency per ACI 214R

Statistics Table

QC-Statistics gives you a table of statistics which can include:

  • Standard deviation
  • Coefficient of variation
  • Moving average test result - applicable to ACI 318 section 5.6.3.3
  • Moving average standard deviation - provides insight into batching and mixing variations
  • Moving average coefficient of variation - also provides insight into batching and mixing variations
  • Range of test and moving average range of test - applicable to ACI 214 section 5.5.3
  • Within-test coefficient of variation - applicable to ACI 214 section 3.4, concrete control ratings
  • Non-statistical items reported can include specimen strengths, test result, slump, air, and temperature
  • 2 age groups can be optionally analyzed at the same time - typically 7 and 28 day

Charts

QC-Statistics reports can include the following charts:

  • Individual and moving average of strength
  • Moving average of standard deviation
  • Moving average of range of test
  • Strength distribution and distribution curve

Form Designer

QC-Statistics form designer will create forms to accomodate the typical needs of statistics users. Some of the report elements which are configureable using the form designer are:

  • Which pages (Project, Mix, Tables, Analysis and Charts) are to be included
  • Portrait or Landscape orientation
  • Where to place the date (or omit)
  • Where to place the mix list (or omit)

  • Titles for and width of the columns in the Statistics Table
  • Statistical results to be included in the Statistics Table
  • Number of tests to be used as the span in moving averages
  • Choice to analyze 1 or 2 ages of specimens
  • Nearly all items on the Analysis Summary are optional
  • Nearly all titles on the Analysis Summary are user configurable
