Brockit Admix Pro – Concrete Worktop Admixture
Brockit Admix Pro is a high-performance admixture designed to be added to cement and kiln-dried silica sand. It creates a smooth, ultra-strong concrete mix for cast-in-place worktops and similar finishes. Developed by Brockit Pro specifically for concrete countertops.
Use
Add to cement and kiln dried silica sand to create a high strength worktop mix
Suitable for indoor and outdoor concrete worktops and cast-in-place applications
Works with all Brockit Pro forms including Standard and Euro Forms
Mix Ratio
Full batch:
| Material | Amount |
|---|---|
| Brockit Admix Pro | 1 bucket |
| Cement | 1 full bag |
| Kiln dried silica sand | 1 full bag |
| Water | 8.4 to 9 litres total |
Half batch (recommended for easier handling and better mixing):
| Material | Amount |
|---|---|
| Brockit Admix Pro | Half bucket |
| Cement | Half bag |
| Kiln dried silica sand | Half bag |
| Water | 4.2 litres |
Water and Mixing
Add 4.2L water to the bucket (for half batch)
Slowly add the admixture, cement and sand while mixing
If the mix feels too stiff, add up to 0.1L more water at a time
Total water per full batch should be between 8.4L and 9L (double the half batch)
Once mixed, allow it to rest for around 8 minutes to let air bubbles rise.
Two Stage Pour Method (Recommended by Brockit Pro)
Stage One
Add 60g fibres per full load (glass or acrylic)
Pour mix into the form, filling just above the reinforcement mesh
Level and allow to set until firm but still tacky
Stage Two
Mix a fresh batch without fibres
Fill to the top of the forms and smooth the surface
Why this method works
Fibres in the base layer increase internal strength
No fibres in the top layer keeps the finish smooth and clean for polishing
Coverage (Cast-in-Place Forms)
| Form Type | Coverage per 20kg mix |
