Challenge
The project encountered key technical hurdles, including high early-age shrinkage cracking, inefficiencies due to multi-step concrete finishing procedures, extended curing requirements, and elevated material consumption, particularly in cement and supplementary cementitious materials (SCMs). These factors collectively impacted structural performance, labor productivity, and scheduling.
Results
Implementation of a next-generation nano-silica admixture provided measurable performance improvements. Cracking was reduced by 70%, mitigating long-term durability concerns. The admixture allowed the consolidation of a previously two-step process into a single-stage placement and finishing operation, increasing operational efficiency. Additionally, the admixture eliminated the need for wet curing and curing compounds, simplifying field operations and reducing labor demands. The optimized mix design enabled a 15% reduction in cement and SCM usage, contributing to lower material costs and a reduced carbon footprint. Overall, the solution substantially accelerated project delivery timelines without compromising quality or performance.

About Indiana and I-65
Indiana is a Midwest U.S. state known for its agriculture, manufacturing, and the iconic Indianapolis 500. Its central location makes it a key hub for transportation and logistics. Interstate 65 runs through the state from Gary to Indianapolis, continuing south to Mobile, Alabama. As a major north-south route, I-65 connects Indiana to key cities and plays a vital role in commerce and travel across the region.
