This spreadsheet provides a computational tool for finding out the matching designation in cement composition according to the EN 197-1:2000 (Standard). It is intended to help demonstrate the possible designations by checking the matching requirements in the term of percentage. The requirements are digitally coded into this programs, so it will feedback the errors on the data entered that does not meet standard requirements, this will allow the user to change the data entered to the data that will be accepted. Some suggestions will also be highlighted on how potential changes can be mode if no matching product is found. The program calculates the % automatically by converting the values to the standard method of reading the table which the composition are considered without the set regulators. This tool provides a faster way of doing the basic calculations needed to read the standard table and at the same time provides more understanding on the standards requirements on the main and minor constituents

Instructions
Data is entered in cells on the “The Product Finder” sheet that are highlighted in orange & blue
When calcium sulfate is used (example gypsum), the values entered in second main constituents and minor constituents will be corrected to 100% without gypsum, therefore the
SMC Corr & MAC Corr shows The EN 197 Correction value for individual second main const
| Minor constituents should not be same with main constituents, the program will check the second main constituents and minor constitutents similarities and disable relevant minor |
Decimals & rounded buttons are provided to round the numbers in case that the values falls between the round numbers on the standard. For example, 5.5% will be rounded to 6 %, 5.4%
In case you’re expecting any specific type of CEM, you can choose them at the Target CEM Box
The reset button it provided to reset the form the original state where no data entered.
Tool Limitations
Not Known
General Standard Requirement Fixed In The Program
CEM II – “M” – Minimum 2 main constituents of S, D, P, Q, V, W, T, L (each >5 %) next to clinke CEM IV – Minimum 1 main constituents of D, P, Q, V, W (each >5%, sum > 11%) next to clinker CEM V – Minimum 1 pozzolanic main constituent P, Q, V (each >5%, sum >18%) next to minimu A constituent (material) can be either “second main constituent” (≥5%) or “minor additional constituents
very good
