The concrete must have less than 10% loss of weight after 100 cycles to fulfill the requirement of the standard. Although the cements N1 and 2 had a significantly higher surface area according to Blaine they did not comply with the requirement whereas cement N4, with lower Blaine, achieved the target. Conclusion The scaling level does not ...
Oct 22, 2008 A comprehensive research project was undertaken to evaluate the effect of specific energy consumption (Ec) on variations of portland cement fineness measured by the Blaine test and sieve analysis. Amine and glycol-based grinding aids (GA) were incorporated at various concentrations of 0.04, 0.06, and 0.08% of the cement weight. At Ec values lower than around 20 kWh/ton, test

Apr 07, 2013 Since both are a measure of particle size, residue is normally linked to Blaine. But not always. It depends on the particle size distribution of the cement and this is driven by several things including mill design, ball charge (or grinding pressure in a roller mill), clinker hardness, gypsum content, and the quantity and hardness of mineral fillers used (eg limestone).
Glycol and amine-based grinding aids were used in the study, and all grindings were realized for the fixed Blaine fineness. The results showed that cement mixtures ground in laboratory exhibited lightly reduction in water demand compared to those ground in an industrial tube mill.
CEMENT GRINDING INTERNATIONAL CEMENT REVIEW FEBRUARY 2015 high Blaine values to achieve the desired results. Furthermore, it is well known that the vent air requirement when grinding slag separately is around 15 per cent less than when grinding clinker or clinker and slag together, because the mill has to be set up for the lowest common denominator
Jan 24, 2019 Where (Blaine area) aids is the specific surface area (Blaine) for OPC clinker in presence of definite concentration of the used grinding aid And (Blaine area) control is the Blaine for OPC clinker in absence of grinding aid.
