Re: what is Rosine Rammler ? The Rosin Rammler distribution is a way of characterising the particle size distribution of powders in the size range encountered in the cement industry. To find it you have to plot the natural logarithmn of the sieve grain size (90u, 45u, 32u etc.) against the double natural logarithmn of 100/residue at that grain ...
manufacturing of Portland cement (PC), cement classes and the hydration of cement will be discussed. Consideration will be given to properties like the optimisation of sulphate and fineness of cement. The particle size distribution is discussed with specific reference to the RosinRammler distribution function. The use of coal combustion by
In the HYMOSTRUC3D model, the cement particle s are modeled as spheres and these spherical particles grow during the hydratio n process. The inputs include the specimen size, the mineralogical composition of the cement, the cement fineness in terms of the Blaine value (RosinRammler particle size distribution is assumed) and the water/cement ratio.
Feb 10, 2004· The concentration d3 is alumina AL 2 O 3, —A—, and the concentration d4 in lime CaO, —C—, in the initial mixture are such that d3/d4 ranges between and produces a cement with a size distribution as represented in a Rosin Rammler diagram has a gradient ranging between and

Also called Rosin Rammler Sperling Bennett (RRSB) distribution. Also called Weibull distribution. It is probably the most wellknown distribution in the cement and the mining industry. RRB is widely used to analyse all types of materials, crushed or not, ground or not. ... The slope of the PSD of a cement, for example, is an ...
When cement composition is constant, the residue and the SSA can be used as a guide to identify changes in psd. For example, the table below shows the estimated slope of the RosinRammler psd from the SSA (in m 2 /kg) and the residue (at 45μm). The slope is based on the particle size data obtained by xray sedimentation.

The cement PSDs will be referred to as <5 µm> and <30 µm> proceeding from left to right in Fig. 1, corresponding approximately to the average size obtained in fitting the PSDs to a RosinRammler distribution . Ordinary ASTM Type I portland cements commonly used today would fall somewhere in between these two curves, but would in general lie ...
Improving the effectivity of work with RosinRammler diagram by using MATLAB R GUI tool Ivan Brezáni1 and Fridrich Zelenákˇ2 A simple, yet powerfull tool for plotting cumulative percent oversize against particle size while using combination of a logarithmic and double logarithmic axis (RR diagram) is here proposed.
