The study covered investigation of concrete with cement, in which 15%, 30% and 45% of the mass was replaced by a mixture of calcined clay (containing about 50% metakaolin and 50% quartz) and limestone in a ratio of 2:1. For comparison, two series of concrete with OPC were used.Web

The method consists on screening the laboratory mill content after each grind run to remove undersize, which is then replenished with an equal mass of new clinker. The procedure is repeated until CL becomes constant, thereby reflecting stable mill conditions delivering cement possessing invariable Blaine fineness, sieve residues, and PSD curves.Web

The model developed using KPCR was tested with data collected from Cemulator (FL simulation tool) as well as with real-time data collected from the cement ball mill.

The reaction always starts at the surface of the cement particles. Thus larger the surface available for reaction, greater is the rate of hydration and strength development. Determination of cement fineness shall not be limited to only Blaine value or a sieve residue — information on the whole particle size distribution (P.S.D.) must be used.Web

In order to investigate the characteristic properties of this cement mixture, cement blends have been produced by using different amounts of SBFC. While the blaine value of SBFC was significantly higher (6953 cm 2 /g) than that of Ordinary Portland Cement (OPC), its chemical composition showed no significant difference. Cement paste ...Web
