effect leading to a chemical activation of the cement hydration, it is now generally accepted that the main effect of the limestone powder is of physical nature (Tsivilis et al. 1999). In addition to cement, limestone particles modify the grain size distribution. The final effect depends on the fineness and the amount of powder.

Performance Enhancer for Portland Limestone Cement (PLC)

In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone. 3. The mill type and process system play an important role.

Influence of grinding method and particle size

Dec 20, 2013 The benefits of using limestone as a partial replacement of Portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO 2 emissions are well known. This paper describes the influence of the producing method (intergrinding or separate grinding) and particle size distribution on properties of Portland-limestone cements (PLC).

Blended Cements with Limestone GCP Applied Technologies

Limestone also generally produces a wider particle size distribution (PSD) for the cement, with both a higher Blaine value and higher residues. Each additional 1% of limestone typically increases the Blaine SSA by 5-8 m 2 /kg (constant mill kWh/t).

However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system.

Optimizing Portland limestone cement GCP Applied

Increased limestone amount usually results in a wider particle size distribution with both a higher Blaine value and higher residues. This, together with the lower clinker factor, negatively impacts the performance of the cement including early strength development, later strength development, long-term durability and dry cement flowability.
