Extremely Durable Cementitious Materials

Extremely Durable Cementitious Materials
April 10-11, 2018
Dallas, TX

ARPA-E hosted workshop entitled “Extremely Durable Cementitious Materials” on April 10-11, 2018 in the Dallas, Texas area.  

The workshop convened leading experts in cementitious material development, manufacturing, distribution, and end-use to identify innovation which significantly improves concrete durability, lowers its energy footprint, and results in next-generation, cost-effective materials to address our current infrastructure challenges. Participants lent their expertise to help ARPA-E explore innovative technologies to determine relevant and compelling metrics that will define a successful research program. 

ARPA-E is interested in cementitious material chemistries, including cements and aggregates that reduce manufacturing energy requirements and improve the durability of concrete, while utilizing existing production equipment and manufacturing facilities. Potential approaches and targeted outcomes included, but were not limited to:

•  Novel cement compositions, process enhancements, and additives that would result in significantly lower energy requirements or improve durability
•  Novel methods to generate or accelerate formation of calcium-aluminum-silicate-hydrate (C-A-S-H), Al-tobermorite, strätlingite, and/or phillipsite, including partial aggregate assimilation
•  Approaches to lower kiln reaction requirements, such as low or no alite and celite
•  Novel biotic approaches to micro-crack mitigation, such as acceleration of the pozzolanic reaction, partial aggregate dissolution, and deposition of calcite and other cementitious minerals
•  Novel chemistries or manufacturing approaches that would result in reduced set time while also improving concrete toughness and durability
  Other potentially transformative cement technology concepts
•  Identification of supply, manufacturing, domestic regulatory, and end-use concerns or restrictions
