In asphalt concretes (ACs), as in cement concretes, fillers are the finest particles among the aggregates. Fillers are powdery materials of various types, most of them pass the 0.063 mm sieve (EN 13043) [], and their inclusion in bituminous and non-bituminous binders and in aggregate mixtures confers special characteristics to these …

The concept of combining calcined clays and limestone to replace more clinker was first proposed by Antoni et al.

The effect of limestone filler (up to 20%) on the degree of hydration, the volume of hydration products, and the optimal replacement of limestone filler in cement pastes at different w/cm ratios ...

The limestone filler incorporated into the mortars was supplied by a company that obtained it as a by-product of limestone grinding. A representative sample was studied. First, the unit weight of the filler was determined to be 1120 kg/m 3 and its fineness was confirmed since of the material passed through the 0.063 mm sieve.

filler Optimal amount of limestone finest powder as a partial replacement of cement is 17-18 %. Although limestone powders insignificantly reduced the compressive strengths of concretes when they were used to replace cement without compensation of the amount of water, full strains are apparently lower for the specimens with limestone filler.

adapted to the cement/limestone blended pastes by simply multiplying all of the volume fractions by a term representing the volume fraction of (base cement and water) paste, or (1-VLF) where VLF is the volume fraction of limestone filler in the blended paste. In this case, the volume balance becomes: Volume balance with limestone filler:

Road Construction: Used as a base material and filler for roads, providing stable support. Cement Production: Crucial raw material in cement preparation, obtained through the calcination process to produce quicklime. Chemical Industry: Utilized in fertilizer production, industrial wastewater treatment, and the purification of flue gas.
