Re: 28 days strength

Dear lalbatros

Firstly I calculated its contain from the Bogue formula in order to facilitated predict the strength of clinker so base on it I could suggest the best target (LSF,SR,AR,..) to my plan. Normally the 28days strength has a multiple linear correlation with the LSF, C3S according to theoritical.

I dont think C3A, Liq or AR have strongly infuence on the 28days strength, so could you explain to me by clearly?

Re: 28 days strength

Dear calahan,

I have no explanation for the correlations observed in your file.

I think it is difficult to reach conclusion from such industrial data.
When the aim is to produce "good clinker", you do not allow bad deviations that would impair the quality.
Therefore, it is no surprise that the most important driving parameters (c2s) are not observed in the data set.
However, this knowledge, that c2s drives long term strengths, has been obtained by observing larger set of data containing larger deviations.

Therefore, it is no surprise that the most important driving parameters (c2s) are not (necessarily) observed in the data set.
However, this knowledge, that c2s drives long term strengths, has been obtained by observing larger set of data containing larger deviations.

Of course, other parameters than c2s can also have an influence.
By doing a naïve correlation on your data, I could only observe the (maybe apparent) influence of {+c3a, -Liq, -AR}.
I don't know if this is real, or -in other words- if this can be used for controling the quality.

Re: 28 days strength

so it mean we have no exactly solution to predict the late strength. I found some plant have different taget (LSF,...) but the same quality (even better with low grade of C3S).
