Cost-effective Uses of Lightweight Aggregate Made from Dredged Material in Construction

It is important for Ohio Department of Transportation (ODOT) and local roadway agencies in Ohio to identify, investigate, and solve the urgent problems to maintain the transportation network in Ohio. Light Weight Aggregate (LWA) and LWA concrete have been identified as one of topics of interest by ODOT, however, the median average estimated cost of LWA in U.S. is $67.50/ton. The goal of this research is to help ODOT identify a much cheaper and readily available LWA that can potentially solve the bridge bumps and enhance the performance of high performance concrete (HPC) through internal cure (IC) and improve the durability of concrete bridge decks. The objective of the student study is to examine the engineering properties of the LWA in the lab, in order to evaluate its potential for use as a fill material and an IC agent. The research team will work closely with Ohio Environmental Protection Agency (EPA) to ensure the product meets state environmental regulations.
