The goal of this study is to identify the critical parameters for control of slurry quality during cementing operations. It appears that the cement mixing process can be split into two different processes: a mechanical one that includes the wetting of the powder, the deflocculation and the homogenisation of the resulting suspension, and

 · Managers of cement plants are gradually becoming aware of the need for soft sensors in product quality assessment. Cement clinker quality parameters are mostly measured by offline laboratory analysis or by the use of online analyzers. The measurement delay and cost, associated with these methods, are a concern in the cement industry.

There are six critical parameters for quality control testing of ready mix concrete that ASTM standards for building consumer confidence, enhancing safety and improving product quality. Sampling – ASTM C172: While the mix is fresh, a representative sample is taken from the center portion of a concrete batch for testing.

2  · 1. Lime Saturation Factor The lime saturation factor (LSF) is a ratio of CaO to other oxides, it is used to control the proportion of cement raw meal. In the operation of the cement kiln, the thermal system of the kiln can be affected by the fluctuation of LSF. The high saturation ratio will make the raw meal difficult to burn to clinker.

Cement analysis: X-ray fluorescence (XRF) The basic principle of XRF analysis is simple. (The physics of what happens is complex, but we won't concern ourselves too much with the details.) If we zap a sample of, say, cement with a beam of X-rays, the X-ray beam will cause other X-rays to be generated within the cement.
