Indiana Facility Offers High Quality Pulverized Limestone

Limestone reactivity experience at Carmeuse enables us to explain both the significance of parameters in the tests (such as pH, grind, additives, etc) and how those parameters will impact results. For example, it is important to select a limestone reactivity test which has very good repeatability and has provisions for experimental controls ...

Lime - Sulphuric Acid

Lime Reactivity. The reactivity of the lime is influenced by the physical structure of the limestone from which it is derived, chemical impurities and the severity of the calcination process. Soft-burned limes are generally more reactive and slake with explosive force to yield a very reactive hydrate or slaked lime .

The lime reactivity test showed the highest reactivity for blends comprising clay and limestone in the proportion of 2:1. Similar result was observed in the case of LC 3 mortar strength. The 28 days cement mortar strength results were correlated with the lime reactivity strength potential test and good correlation was observed.

What happens when acid reacts with limestone? | Questions ...

Jun 15, 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
