Ultratech Portland Pozzolana Cement, .

Portland cement clinker is either interground or intimately blended with specified quantities of gypsum and pozzolanic materials to produce Portland Pozzolana cement. Pozzolanas by themselves do not have cementitious properties but reacts with calcium hydroxide in the presence of moisture at normal temperature to form compounds having cementitious properties. The concrete produced by using ...

Tensile strength enhancement in interground .

Interground fiber cement (IFC) is a new process where fibers are ground in with the cement clinker during the dry cement manufacturing process. With IFC considerable strength enhancement can be achieved compared to ordinary cement even at a fiber volume as low as 0.2% due to homogeneous fiber distribution and fiber surface modifications associated with the milling process. The cracking ...

The early-age compressive strengths are beneficially impacted by the presence of limestone whereas the clinker factor does not play a significant role in later-age strengths in both the blended and interground systems. The study paves the way for development of ple-material binders containing higher levels of cement replacement that demonstrate early and later age properties that are ...

A methodology to extract the component size .

The interground systems are found to outperform the blended systems, plausibly because of the difference in size distributions of the clinker and limestone fractions between the PLCs and the blended systems. A novel methodology to extract the particle size distributions of the components in the interground systems is reported. This method, applicable for several types of -component .
