Standard HP50, High Performance Bag Mix, 50lb

Fishstone is proud to introduce a smarter, more flexible way to make high-performance concrete.

Fishstone HP50™ Standard Mix is a precision-blended universal concrete bag mix designed for fabricators, artists, contractors, and makers who want the freedom to customize one core mix for multiple applications. Instead of stocking several specialty mixes, HP50 allows you to start with a high-quality base and easily modify it for GFRC, ECC, lightweight concrete, carving mixes, cast-in-place projects, troweled finishes, decorative concrete, and more.

Whether you want a simple just-add-water high performance mix or a fully engineered custom blend, HP50 gives you complete control while maintaining consistency from bag to bag.

What Makes HP50 Different?

Fishstone HP50 contains the essential ingredients found in advanced high-performance concrete systems, including:

• Premium white cement
• Carefully graded sands
• Pozzolans
• Mineral admixtures
• Precision-controlled dry blend components

From there, you decide how to customize the mix for your specific project.

Use it straight from the bag or enhance it with compatible Fishstone admixtures and fibers including:

• KongKrete Polymer
• Super-SIX Admix
• Carving Admix
• Decorative aggregates
• Lightweight fillers like Featherlight
• Integral pigments
• Glass fiber, PVA fiber, carbon fiber, and more

Designed for Consistency

Every HP50 bag is manufactured to strict tolerances and weighs exactly 50 lbs (±0.2 lb). That means:

• More accurate pigment dosing
• Consistent admixture loading
• Repeatable color results
• Reliable performance from batch to batch

This level of precision is especially important for decorative concrete, GFRC panels, countertops, furniture, architectural concrete, and color-sensitive applications.
