February 2009 - The new Conformity Database v2.1 has seen some major changes which are:...

Start-up

The main start-up screen has changed. The old menu for editing has been removed as this has become a comprehensive master system analysis tool. Editing now occurs from the cube datasheet in the control screen.

Main Relationship Analysis

The Conformity Database can now deal with an unlimited amount of mix designs. The system now uses batchbook references.

Mix Design

Mix Design can be of any concrete mix design imaginable. The only stipulation is that all mix designs must have an established relationship with the main concrete mix design and be of the same family of concrete mixes. An EN206 mix family is determined by the concrete mix constituents being of the same type and physical properties, including the cement type.

Database Master Analysis Tool

The development tool used to re-write the system has been left in place as I think this offers some advanced features for the user.

Database Strength Lists

The system will run without any strength lists being used. The system runs entirely from the input MRA, density and slump adjustment data. This is because users may run their own strength lists generation tool.

Consistency Conformity

EN206 Consistency conformity analysis has now been enhanced to include both spot and composite sampling. The previous system used the most onerous conformity requirements.

Quick View Screen

7 to 28 Day Strength relationship, hereafter known as correlation. This is now totally automated and the user inputs both the 7 days and the 28 days MRA strength data. The system will calculate any correlation deviation. There is now a detailed correlation history chart available. This may show correlation trend changes during the course of the annual seasonal climate changes! It may also indicate problems with cement quality. It should noted that at least three 7 and associated 28 days results should be input to activate the correlation automation formula.
