THE QUANTITATIVE DETERMINATION OF ALITE AND BELITE RESIDUES IN PARTLY HYDRATED CEMENT PASTES

The alite and belite contents of the clinker residue of partly hydrated cement pastes can be obtained by X-ray quantitative analysis. The X-ray method used is essentially the same as that for unhydrated cements. The results of determinations on pastes from three different portland cements demonstrates the increase in hydration both of alite and belite at any given time with increase in the water/cement ratio. /Author/
