The primary objective of this Extremely Durable Cementitious Materials project is to engineer an ultra-acid-resistant low-calcium alkali-activated (geopolymer) cement paste specifically for wastewater infrastructure applications.

The objective of this project is to engineer living materials to serve both biological and structural functions.

The first in a series of testing programs at ÃÛÌÇÖ±²¥ Boulder CIEST investigating performance of critical lifeline systems under extreme loading conditions.

Project included development of a bi-directional loading system to apply simultaneous axial and lateral loading to 6 in. diameter columns and splice connections. Nearly 60 full-scale tests were conducted to support evaluation of a new structural building system for seismic applications. Accredited testing performed to ISO/IEC 17025 standard following protocols provided by FEMA 461.

 In summer 2019, former masters student David Kyle Anderson conducted 28 tension tests on 5 different types of wire mesh used for soil stabilization at CIEST.

Structural assessment of cold-formed steel diaphragm assemblies was conducted in accordance with AISI S907. The cantilever-style tests were performed on 12 x 12 ft square specimens and included both static and cyclic test protocols.

The focus of this project is to model the shear strength of concrete panels that have experienced alkali silica reaction.
