Splet03. nov. 2024 · Four variables contributing to the synthesis of C-S-H/PCE nanocomposites, including feeding sequence of reactants, the flow rate of reactants, concentration of reactant solution, and the dosage of PCE, were studied. The dosage of PCE refers to the weight percentage of Ca(NO 3) 2 ·4H 2 O. Four levels were selected for each variable .

SpletA high performance polycarboxylate superplasticizer (PCE) was successfully synthesized by a polymerization reaction among acrylic acid (AA), maleic anhydride (MA) and isopentenyl polyethylene glycol (IPEG) through redox initiation system. The composition and amounts of initiation system, and the ratio of monomers were investigated respectively. SpletA life cycle assessment (LCA) of the PCE synthesis, the packaging materials used, and the transportation of the PCE were conducted based on the ReCiPe method. The results indicated that liquid-state PCE has a far greater environmental impact at 60% than solid-state PCE, which is less significant at 40%.
