Effects of a binary microfiller-based superplasticizer on the workability, strength, and durability of concrete

This article investigates the influence of a new-generation high-performance superplasticizer, developed by the Arment Construction Chemicals Company, on the properties of fresh and hardened concrete. The innovative admixture is characterized by a synergistic polymix formulation of advanced polymers, combined with a proprietary binary filler system. The primary objective of the research is to evaluate the efficacy of this composite chemical in enhancing workability, mechanical strength, and durability beyond the capabilities of conventional superplasticizers. The experimental methodology involved preparing concrete mixtures with varying dosages of the new superplasticizer, which were compared against control mixes and those containing traditional water-reducers. The fresh properties assessed included slump, slump retention over time, and setting time. For the hardened state, compressive and flexural strength tests were conducted at different curing ages, alongside an analysis of durability indicators such as water permeability and resistance to chemical attack.
