The American Concrete Institute Foundation's Concrete Research Council (CRC) has announced grants for six projects this year, including two with environmental themes: "Embodied Carbon in Construction Calculator Tool," led by Kathrina Simonen of the University of Washington-hosted Carbon Leadership Forum and Phil Northcott of C-Change Labs; and, "Effective Characterizations of Recycled Concrete
Aggregate for Concrete Applications," led by Jiong Hu, University of Nebraska-Lincoln and Tara Cavalline, University of North Carolina at Charlotte.
Utilisation of recycled concrete
aggregate (RCA) in concrete has been engaged due to awareness of society in natural resources protection.
It can also be used on various recycling applications including construction and demolition waste, recycled concrete
and reclaimed railway sleepers.
recycles not only conserve many natural aggregate resources but also reduce construction waste pollution in the environment, in line with the requirements for the sustainable development of the construction industry.
aggregates were used in developed countries as a replacement to natural coarse aggregates for stabilizing the base course of road constructions, leading to save the natural reserve for generations to come.
Once it's been crushed, the recycled concrete
doesn't look much different than gravel created by crushing boulders.
The topics of the conference included Delay and Disruption in the Construction of Mega Projects; Improving Aesthetics and Durability of Concrete with the Use of Innovative Chemicals; Online Live Monitoring of Concrete Placement Operations; Surface Protection for Manufactured Concrete Products; Eco-mechanical Performances of Concrete Made with Recycled Aggregates; Recycled Concrete
: Opportunities in Qatar and An Overview of Structural Health Monitoring Systems For Concrete Structures.
The result is an affiliated company called ReRock Materials Inc., which creates recycled concrete
and aggregate products.
specifying the use of a portion of recycled concrete
for new pavement building in 2012, the consultant said.
2004) and recycled concrete
aggregates (RCA) (BS EN 8500-1 2006) are subjects of debate for application in bases and sub bases.
