CLARENA® Concrete Admixture Technologies for Clay Mitigation

In many regions of the world, it is becoming increasingly difficult to source high-quality aggregates, leaving concrete producers with little choice but to use alternative materials such as manufactured sand or quarry dust. The presence of expansive clays, angular shapes and less-than-optimal gradations in these materials adversely affect the quality of the concrete produced. Poor workability, loss of strength and high performance variability increase operational and quality control difficulties and production costs.

That is why GCP Applied Technologies developed the CLARENA® portfolio of admixtures for clay mitigation, a series of mid- to high-range water reducers that compensate for lower quality aggregates.
