Additive Manufacturing with Cement-based Materials

Ongoing
Objective - Develop the measurement science tools and scientific knowledge base for performance-based standards for reinforced 3-D printed concrete structures. Background - Current 3DCP construction practices resemble reinforced masonry construction, as shown in Figure 1. Similar to reinforced

Engineered Materials for Resilient Infrastructure Program

Ongoing
Objective - To develop and deploy measurement science to reliably assess the current and future performance of engineered materials in support of resilient infrastructure given exposure to chronic (e.g., materials degradation) and episodic (e.g., earthquakes) hazards. What is the technical idea? To

Hydration Reactions in Microstructures Project

Completed
Objective - Generate and publish reaction rate data and enhanced computer modeling tools to better understand and predict the rates of microstructure development and phase interactions in portland cement concrete binders. What is the new technical idea? Reflection digital holographic microscopy (DHM
