With so many different mix designs for concrete, one that we find interesting is "geopolymer concrete", also known as geocretes At Unfound Creations, we’re passionate about innovation, and geopolymer concrete is an interesting material in terms of its low-carbon content, especially through the use of fly ash, a staple in our mixes. But what exactly is geopolymer concrete, and why is it making waves in the world of design and construction?
Geopolymer concrete is quite different from the traditional concrete you might be familiar with. While regular concrete is made from a mix of cement, water, and aggregates like sand and gravel, geopolymer concrete takes a different approach. Instead of cement, it uses industrial by-products like fly ash or slag combined with alkaline solutions to form a strong, durable, and eco-friendly material.
The Basic Ingredients of Geopolymer Concrete
The key ingredients that make geopolymer concrete unique are:
Alkaline Activators: These are chemical solutions, typically a mix of sodium silicate and sodium hydroxide, that help bind the materials together.
Industrial By-products: Materials like fly ash (a by-product of coal combustion) or slag (a by-product of metal smelting) replace traditional cement.
Aggregates: Like regular concrete, geopolymer concrete uses aggregates, but the mix can be adjusted to create various textures and finishes, perfect for custom artwork.
What Makes Geopolymer Concrete Different?
There are several reasons why geopolymer concrete stands out:
Eco-Friendly: Traditional concrete production is energy-intensive and a significant source of carbon dioxide emissions. Geopolymer concrete, on the other hand, uses industrial waste products, reducing environmental impact and conserving natural resources.
Durability: Geopolymer concrete is incredibly strong and resistant to chemicals, fire, and even weather extremes. This makes it ideal for both functional and decorative pieces that are built to last.
Versatility: The material’s composition allows for greater flexibility in design. Whether you’re looking for sleek, modern furniture or intricate wall art, geopolymer concrete can be molded and finished to meet your exact specifications.
Why Use Geopolymer Concrete
Its eco-friendly properties and durability make it an excellent choice for consideration in certain concrete applications, especially if industrial waste products are readily available. Geocretes high early strength, reduced consumption of natural resources, cost-effectiveness, capacity to form different structural configurations and ability to remain intact for extended periods without repair works, are very attractive features.
