This study investigates the impact of polycarboxylate superplasticizers (PCEs) on the calorimetric and mechanical properties of mortar. Using two different PCEs, researchers evaluated their effectiveness in enhancing mortar workability, heat release, and compressive strength. The superplasticizers, when added at varying dosages, influence hydration kinetics and overall heat generation in cement-based mortars. Low dosages of PCEs promote faster hydration and more heat production, improving early strength development. In contrast, higher dosages delay hydration, reducing heat release and extending the setting time.
The study found that PCE1, with its higher carboxylic charge density, showed superior performance in improving the mechanical strength of mortar at 7 and 28 days, making it more suitable for use in diverse climatic conditions. The findings suggest that the right selection of superplasticizers can significantly optimize the cement mix for better structural performance. This research offers valuable insights for construction industries seeking to enhance the quality and efficiency of their materials.
