Materials Management Solutions

Availability of good quality aggregates and cementitious materials diminishing globally. Sustainability Advantages: CLARENA® RC: Recycle and reuse rejected loads. Preserve natural quarries. CLARENA® MC: Preserve local, natural resources. Reduce waste. DARAGRIND®: Improve SCM process efficiency.

1-5% of all fabricated ready mix concrete is returned

Poor quality and unconventional aggregates being used (i.e. manufactured sand) for many applications: Quality associated with clay negatively impact production costs and performance; Results in plastic concrete with poor rheological properties (i.e. pump, flow, consolidation issues); Lower quality and less durable concrete produced when aggregate deficiencies not managed effectively; Increased process variability, production costs and quality control for aggregate and ready-mix produce.

What to do with millions of yd3 of concrete that’s returned every year? NRMCA estimates 1-5% of all fabricated ready mix concrete is returned (~284 million m3, or 371 million yd3) produced in N.A. in 2019).

  • CLARENA® Clay Deactivation Technology

    Reacts with clay through adsorption and intercalation, thus reducing absorption of water and admixture. Extends quarry life with quality aggregates, better fines management & additional yield and productivity. Consistent admixture dosage and repeatable slump and air performance. Potential to reduce quarry aggregate waste.

    CLARENA® concrete admixtures mitigate the negative effects of aggregate shape, gradation, and clay content, and increase the usable amount of aggregate from a given quarry, while improving admixture performance and concrete quality.
