The effect of Sika Viscocrete (Polycarboxylate- based macromolecule polymer) on the equilibrium thermodynamic of K₄Fe (CN)₆ in neutral potassium chloride and its application for OPC (Ordinary Portland Cement) paste were added. Portland cement is manufactured from raw limestone, clay, mudstone, and shale deposits. The cyclic voltammetry of Sika Viscocrete with different concentrations with K₄Fe (CN)₆ at 290K was measured using a potentiostat, delivered from the USA in KCl (0.1 M) as the medium, glassy carbon electrode, platinum wire electrode, and standard Ag/AgCl electrode are used. Different solvation parameters were evaluated by using various scan rates. Also, the mechanisms and the stabilization of the complexes formed are discussed. The compressive (compressive ability) strength of the cement mixture with water at curing times (1, 3, 7 and 28 days) was determined by using different percentages of polycarboxylate-based macromolecule as an environmental application. The results indicated that Viscocrete is combined with the iron present in the cement and increase the compressive ability using the concentrations of macromolecule material, 0.25% and 0.5% then decreases with the concentrations 0.75% and 1%.
