ABSTRACT
The broader impact/commercial potential of this I-Corps project is the development of a type of concrete that reduces waste. More than one billion cubic yards of ready-mix concrete produced in the United States is returned to concrete plants every year. Much of this concrete is discarded as waste or washed out to reclaim the aggregates used in the system. This waste results in hardened concrete in landfills, contaminated washout water, and increased greenhouse gases. Reducing this may significantly improve sustainability by preventing unnecessary material in the landfill and reducing use of scarce water resources for washing, as well as improving operating costs. Furthermore, the main reason for truck rejections of concrete every year is due to the strict adherence to the 90-minute time limit. The technology is a concrete additive that allows mixed concrete to ?sleep? to preserve the quality.
This I-Corps project is based on the development of an improved concrete formula to allow extended mixing times without negatively impacting long-term durability. As traffic and road congestion has gotten progressively worse, this rule has unnecessarily increased construction cost and waste concrete. The proposed technology may extend mixing times by up to 150 minutes without negatively impacting the long-term durability of concrete mixtures. Recent studies examined hardened concrete properties such as compressive strength, freeze-thaw, and surface resistivity and indicate that the discharge time had no significant impact on the fresh properties, surface resistivity, and freeze-thaw durability up to 150 minutes. This technology may improve discharge time limits and extend specifications.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
Intellectual Merits
This research project lead to change the national ASTM Standards that was followed for almost 100 years. We are ready to dissiminate our findings once we submit the final report. We have been contacted by so many local and national organizations to present and to write conference and journal papers, even books about this important issue. we will make sure to share the resuts of these hundreds interviews (concrete providers, owners, engineers, architects..ect) with engineering students at engineering universities and colleges to have them well informed about this latest innovative technology.
Broader Impact
The results of using our product will save significant amout of time and money and will save the environment by reducing CO2 emmission coming from transportation and cement production. It will also save significant amount of landfills needed to dump rejected concrete at.
The results of our interviews proved with no doubts that this is a win win situation for business owners and for us. We are really ready to go to stage 3 and start our own company as soon as possible after the encouragement and support that we have seen during these too many visits and interviews. That was a product that everyone was waiting for and it endeed solved one of the major problems concrete industry was waiting for.
