Understanding Limestone in Cement Concrete Construction ...

Mar 26, 2015  The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation ...

Carbonation resistance of concrete: limestone addition ...

It is shown that the carbonation of concrete increases with increasing limestone content, within the range permitted by standard BS EN 197-1:2011. This effect, however, is less marked for concrete designed on an equal strength basis to the corresponding Portland cement (PC) concrete than concrete designed on an equal water/cement (w/c) basis.

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
