CX-270224: Effect of Gamma Irradiation on the Microstructure and Mechanical Properties of Nano-modified Concrete – Vanderbilt University

Vanderbilt University, in collaboration with Oak Ridge National Laboratory, proposes to perform gamma irradiation of nano-modified concrete and appropriate control reference samples that are also relevant to current and historic concrete mixes. The research plan will consist of multiscale chemical and mechanical characterization of the performance of nano-modified concretes before and after exposure to gamma radiation. The project will focus on nano-silica and nano-halloysite in Portland cement concrete made with ground granulated blast furnace slag.
