Anti-Clay Agent (Clay-Shielding)Manufactured-sand grade
- Manufactured sand
- Clay shielding

- Volume discount
A clay-shielding component designed for montmorillonite/illite clays in manufactured sand and aggregate. It preferentially adsorbs and blocks interlayer cations, reducing PCE consumption and recovering slump retention.
Resists aggregate clay · Protects PCE · Recovers slump loss
- Form
- Liquid
- Recommended dosage
- 0.05% – 0.20% by binder weight (rises with clay content)
Overview
This anti-clay agent is a small-molecule competitive-adsorption component. It is captured first by layered clays (e.g. montmorillonite), occupying interlayer cation-exchange sites, thereby reducing consumption of the PCE macromolecule and recovering the slump loss and workability loss caused by clay.
Key benefits
- Relieves fast slump loss and poor flow from high-clay sand
- Protects and boosts effective utilization of PCE
- No chloride — safe for reinforcement
- Easy to blend with superplasticizer and retarder
Usage
Add together with or before the superplasticizer; raise dosage with aggregate clay content. A clay-compatibility trial is recommended to set the optimum blend.
Typical use
High-clay manufactured-sand concrete, ready-mix and projects with unstable local aggregates.
