The 50% Solution
 Technical Issues Arising from
Cement Substitution Rates of 50% or Higher

 

One approach to reducing the carbon footprint of concrete is to increase the use of supplementary cementing materials (SCMs – fly ash, slag, silica fume, metakaolin, ground limestone, etc) as a replacement for Portland cement. The focus of Anna Maria XI will be on the technical issues that arise with substitution rates of 50% or higher. These issues may include: 

bullet Workability and rheology bullet Setting times bullet Rate of strength development bullet Durability bullet Permeability bullet Cement/SCM/superplasticizer interactions bullet Availability and characterization of SCMs bullet Economic considerations bullet Benefits bullet Educating engineers/architects/specifiers/contractors bullet Changing codes and specifications

The purpose of the workshop will be to bring together people from the different sectors involved (engineers, educators, specifiers, material producers) to discuss these technical issues. The goal is to provide input on future directions in both research and practice.
