Description
Clarena® CM150C is a clay mitigating asmixture used in quarries. The Clarena® CM150C family of products is a new class of materials specifically designed and formulated to meet the needs of the concrete producer. It is designed to selectively react with clay contaminants in both coarse and fine aggregates. This highly engineered, irreversible chemical reaction can eliminate the negative effects of clay-bearing sands and aggregates in concrete. Even a relatively trace presence of clay in a concrete mix can have a two-fold negative impact.
Firstly, the mix will have a higher water demand due to the clay’s absorbency. Normally, this increased water demand would be addressed through superplasticizing admixtures. However, the secondary negative impact of clay is its affinity for polycarboxylate (PCE) molecules, which diminishes the efficacy of PCE-based admixtures. Clarena® CM150C reacts with the clay particles, eliminating the PCE affinity, and enabling PCE-based admixtures to work with increased efficiency.
Application areas
- Sand and coarse aggregates
Benefits
- Allows higher use of manufactured sand in mix designs
- Uses clay bearing aggregates (natural and crushed) without compromising on concrete performance
- Increases use of lower-quality or clay contaminated aggregates
- Enhances concrete performance by reducing water and admixture requirements through the effective neutralization of clay particles
