What Makes Unfound Creations’ Low Carbon concrete Mix Superior?

At Unfound Creations, we’re crafting more than just concrete—we’re pioneering a low carbon concrete mix designed specifically for Glass Reinforced Concrete (GRC/GFRC) and micro-cement. By incorporating up to 14% waste materials like silica fume and fly ash, we’re turning industrial byproducts into a high-performance, sustainable solution that’s perfect for lightweight, versatile, and design-driven projects. So, what sets our mix apart for architects and designers in New Zealand? It’s all about the science of pozzolans, a reduced reliance on cement, and the exceptional properties that make GRC and micro-cement shine.

Pozzolans: The Power Behind a Low Carbon concrete mix for GRC and Micro-Cement

Pozzolans might sound technical, but they’re the key to unlocking the potential of our low carbon mix. These siliceous or aluminous materials—named after the volcanic ash that made Roman concrete legendary—don’t harden on their own. Instead, they react with lime (calcium hydroxide) in the presence of water to form additional cementitious compounds. This pozzolanic reaction is what gives our GRC and micro-cement their edge.

We use two standout pozzolans: silica fume (also called micro silica) and fly ash. Silica fume is a superfine byproduct of silicon production, while fly ash comes from coal-fired power plants. By blending these waste materials into our mix, we’re not just diverting them from landfills—we’re enhancing the performance of GRC and micro-cement in ways that traditional mixes can’t match.

Cutting Cement, Boosting Performance

Cement production is a carbon heavyweight, responsible for around 8% of global CO2 emissions due to its energy-intensive process. For GRC and micro-cement—where precision and efficiency matter—our low carbon mix reduces cement content by up to 14%, replacing it with silica fume and fly ash. But here’s the best part: this doesn’t compromise quality. It elevates it.

During the curing process, cement releases lime, which our pozzolans eagerly consume. This reaction forms extra calcium silicate hydrate (CSH)—the “glue” that gives concrete its strength—while refining the material’s microstructure. For GRC, this means a denser, tougher matrix that pairs perfectly with glass fibers. For micro-cement, it creates a smoother, more durable finish. Less cement, better results—it’s a smart choice for sustainable design.

Why Superior? Strength, Impermeability, and Design Versatility

Architects and designers in New Zealand need materials that perform under local conditions—think coastal humidity, seismic demands, or the desire for sleek, modern aesthetics. Our low carbon mix for GRC and micro-cement delivers, thanks to the unique benefits of silica fume and fly ash.

• Strength: In GRC, silica fume’s ultra-fine particles (100 times smaller than cement grains) enhance the bond with glass fibers, boosting tensile and compressive strength. Fly ash complements this by contributing to long-term strength gain. For micro-cement, the result is a robust, crack-resistant surface that holds up under wear.

• Water Impermeability: The pozzolanic reaction reduces porosity, making both GRC panels and micro-cement finishes less permeable to water. This is a big deal for exterior cladding or wet-area applications, where moisture resistance extends lifespan and cuts maintenance.

• Durability: From resisting chemical exposure to standing up to New Zealand’s weather, our mix ensures GRC and micro-cement projects last. For GRC, this means lightweight panels that don’t sacrifice toughness. For micro-cement, it’s a flawless finish that endures.

Tailored for GRC and Micro-Cement Applications

GRC and micro-cement are go-to choices for designers who value flexibility and sustainability. Our low carbon mix takes them further. GRC, with its lightweight strength, is ideal for architectural cladding, intricate facades, and precast elements—think sculptural forms or textured panels that turn heads. Micro-cement, with its seamless, thin-layer application, suits floors, walls, and even furniture, offering a minimalist vibe with maximum durability. By integrating waste-derived pozzolans, we’ve fine-tuned our mix to enhance workability and finish, giving you the freedom to push creative boundaries without the environmental guilt.

Sustainability

New Zealand’s design community is leading the charge toward sustainable building, and our low carbon mix fits right in. By cutting cement use and repurposing industrial waste, we’re lowering the carbon footprint of every GRC panel and micro-cement surface. It’s a practical step toward greener construction that doesn’t ask you to rethink your workflow—just your material choices. Plus, with local conditions in mind, our mix ensures your projects thrive in Aotearoa’s unique environment.

The Science Says It All

This isn’t guesswork—it’s proven. Research shows silica fume can boost GRC’s strength by 20-30%, while fly ash improves durability and reduces shrinkage in both GRC and micro-cement. These benefits have been tested in real-world applications globally, and now they’re available through Unfound Creations. It’s science you can build on.
