Carbonate and Gypsum - MAFIADOC.COM

An estimate of the calcite and dolomite contents can be obtained by taking measurements after 1 to 2 min (calcite) and after 1 to 2 h (calcite + dolomite). More accurate determinations of calcite and dolomite require development of time-pressure curves, using either a mercury manometer (Skinner et al., 1959; Turner & Skinner, 1959, 1960) or a ...

Cement hydration - Understanding Cement

Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the dashes indicating ...

To evaluate the effect of calcite on cement hydration kinetics, an isothermal calorimeter (TAM air brand) operating at 25 °C was used to measure the hydration heat flow and cumulative heat flow of the anhydrous cement samples (A, B and C) during 8 days. All isothermal calorimetry tests were performed at w/c ratio equal to 0.4.

Limestone, mainly consisting of calcite, is a permitted additive to Portland cements often up to a 5 wt.% limit. It is shown by experiment and calculation that much, if not all, of this calcite is reactive and affects the distribution of lime, alumina and sulfate and thereby alters the mineralogy of hydrated cement pastes.
