In the spring of 2024 CIEST hosted a student tutorial for the non-profit, Engineers without Borders or EWB. The tutorial was aimed at giving students experience making concrete before a trip to Nepal.

The intent of this study is to investigate the difference between a serrated faced flange connection and a non-serrated faced flange connection; mainly to determine whether one would leak sooner than the other.

The intent of this study is to define the seismic response of iPVC pipeline systems with couplings and to illustrate procedures for interpreting laboratory results to seismically classify pipeline system performance following developing ASCE seismic guidelines.

Project Title: Hoop Tensile TestIndustry Partner: PSI LabCIEST Personnel Participants: John HindmanYear: 2022Project Summary:The CIEST Laboratory successfully completed testing pipe liner samples for “apparent hoop tensile

The intent of this study is to impose external loading conditions to test specimens that are representative of the significant deformations possible during earthquake-induced ground motions such as landsliding, fault rupture, and liquefaction-induced lateral spreading, characterizing the pipeline system capacity.

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.
