Abstract:

This study investigated the feasibility of using colloidal nanosilica (nS) as microstructure modifier and polymeric microspheres (MS) as alternative air-entrainment systems for Indiana Department of Transportation (INDOT) bridge deck concrete. These admixtures have gained interest due to their potential to modify the air-void system, enhance freeze-thaw (F/T) resistance, reduce permeability, and improve early-age performance. However, their field applicability depends on understanding their sensitivity to mixture composition, type of batching process, consolidation practices, and water-to-cement (w/c) ratio. The objectives of this research were to: (1) conduct field trials incorporating nS and MS and evaluate both fresh and hardened properties, (2) compare air-void characteristics and F/T performance between field and a companion laboratory mixtures, (3) evaluate the influence of mixing method, compaction effort, and type of batching process on mechanical and durability properties, and (4) quantify the effect of w/c ratio on nS mixtures, including the extent of calcium hydroxide (CH) reduction in paste systems.
