Determination by Ultraviolet-Visible Spectroscopy of Adsorption of the Superplasticising Admixtures Dynamon SX 32 and Dynamon SRC 20 in Calcined Clay of Layers A, B and C of the Yaguajay Deposit and toefficients for point inferior to 3%. The adsorption of the superplasticizers in the roasted clays oscillated between 40 and 60%. The results demonstrate the feasibility of using the method proposed for the analytic determination as well as the strong adsorption that these superplasticizers present in the roasted clays for the studied systems.
