Standing at the George Floyd memorial in Minneapolis last month was extremely moving — and it brought me straight back to these five pieces.

This is my BLM Heart Series, made in order:

1. King of Hearts — paying respect to the fallen victims of gun violence. His heart is formed by arms and clasped hands, on a base shaped like the Adinkra symbol for peacemaking.
2. Queen of Hearts — his female partner.
3, 4 & 5. MUM DU Silver, Gold, and Copper — for the mothers of shooting victims who have stood up peacefully in honor of their children, in times of great grief and loss. Silver and gold for strength, resilience, and hope. Copper as a conductor of energy — a bridge between earth and spirit, tied to love and vitality.

Five pieces, one story. Peace and healing to all.

TruCast SiX in action.

In this real shop casting, we used TruCast SiX with HP50 and 1/2" AR glass fibers to create a high-performance concrete kitchenette.

Mix shown:

• 50 lbs HP50
• 5 lbs TruCast SiX
• 1.5 lbs 1/2" AR glass fiber
• 8 lbs water

TruCast SiX is our new multi-function powdered admixture developed for self-consolidating concrete, GFRC, UHPC-style mixes, countertops, furniture and other architectural precast applications.

We’ve been working on this one for quite a while and it’s finally ready.

TruCast SiX is our new ultra-performance powdered admixture and the replacement for Super-Six.

Rather than simply renaming Super-Six, the formulation was completely reworked. TruCast SiX is designed for self-consolidating, high-performance concrete with improved flow, particle packing, surface quality and consistency.

It can be used for GFRC, ECC, UHPC-style mixes, SCC, concrete countertops, furniture and architectural concrete.

For those of you who have been using Super-Six, one important change is the dosage. TruCast SiX is typically used at about 20% of Portland cement weight, compared with approximately 5% for Super-Six, so it is not a pound-for-pound replacement.

We’ve also put together new mix recommendations to make the transition easier.

Take a look at TruCast SiX and the new MixRecipe page on our website.

Can concrete be made without silica sand?

While traditional silica sand remains one of the most proven and widely used aggregates in the industry, growing interest in recycled materials and alternative mix designs has prompted researchers and fabricators to explore new possibilities.

In our latest article, we take a balanced look at silica-reduced concrete, recycled glass aggregate, ground-glass pozzolans, ASR considerations, and the real-world pros and cons of these emerging materials.

The Collomix XO mixer line has officially been discontinued and replaced by the new and improved XQ series — and we’ve now fully transitioned over to the next generation platform.

The XQ line was introduced about a year ago, and after seeing the improvements firsthand, we’re excited to now be 100% focused on the new XQ models moving forward.

Fishstone has proudly carried Collomix mixers for over a decade because they’ve consistently delivered:
✔ Excellent build quality
✔ Reliable performance
✔ Great warranty and service
✔ Professional-grade mixing power

So what’s new with the XQ line?

🔹 MATERIAL-SPECIFIC PADDLES
Unlike the older XO mixers, the new XQ mixers do NOT include a mixing paddle.

That’s intentional.

Different materials require different paddle designs, so the XQ system allows users to choose the ideal paddle for exactly what they’re mixing:
✔ GFRC
✔ UHPC
✔ Mortars
✔ Self-levelers
✔ Epoxies
✔ Concrete mixes and more

🔹 NEW HEXAFIX QUICK-CHANGE SYSTEM
The new Hexafix connection system allows for:
✔ Fast paddle changes
✔ Easier cleaning
✔ Quicker transport and storage
✔ One motor paired with multiple paddle styles

🔹 ADVANCED DIGITAL ELECTRONICS (XQ4 & XQ6)
One of the biggest upgrades is the new electronic control system featured on the XQ4 and XQ6 mixers.

These models now include:
✔ Digital RPM display
✔ Precise electronic speed adjustment
✔ Built-in digital timer

For high-performance concrete mixes, consistency matters. Being able to repeat the same mixing speed and mixing time from batch to batch helps improve repeatability and overall mix quality.

And it’s not just handheld mixers — Collomix also produces some of the best vertical shaft pan mixers available, ideal for ultra high-performance and high-performance concrete mixes where thorough, consistent mixing is critical.

BIG NEWS — WE MOVED!

Fishstone is proud to announce that we’ve officially moved into our brand new 30,000 sq ft concrete tilt-up facility in Elkhorn, Wisconsin.

This new building was designed from the ground up to help us better serve the decorative concrete industry with expanded inventory, improved shipping, product development, training space, and future growth.

What started as a passion for high-performance concrete has grown into something much bigger — and we’re just getting started.

We’ll also be sharing photos and videos from the entire building process soon, including behind-the-scenes shots of the tilt-up construction and the journey from empty site to finished facility.

Thank you to all of our customers, friends, and supporters who helped make this possible.

New Location:
Elkhorn, WI 53121

More products. More innovation. More concrete.
