MACt GFRC Premix – SCC Silica Free

MACt GFRC Premix – SCC Silica Free

MACt SCC Premix is a superior product that has been specifically developed for the creation of glass fibre reinforced concrete (GFRC) products. It has been designed to provide a much higher tolerance to thermal shock and cracking that can occur from general GFRC, making it an ideal solution for high-quality basins, bathtubs, and other custom GFRC products.

One of the key benefits of MACt SCC Premix is its superior safety profile. It is a silica-free product, which means that it is much safer to manufacture and use than traditional GFRC products that contain silica. Silica is a well-known hazard in the construction industry and can cause serious health problems such as silicosis, a chronic lung disease. By using MACt SCC Premix, contractors and manufacturers can reduce the risk of harm to themselves and their workers.

MACt SCC Premix is also incredibly easy to work with. It has a smooth, creamy consistency that is easy to pour and shape, making it perfect for use in a wide variety of applications. This product is also incredibly easy to mix, requiring only water and the premix itself. This makes it ideal for use on job sites where time and resources are at a premium.

Another significant advantage of MACt SCC Premix is its ability to withstand thermal shock. This is a significant advantage over other GFRC products, which can often crack or even shatter when exposed to sudden changes in temperature. This product has been developed to provide a much higher level of durability, making it ideal for use in areas that are exposed to extreme temperatures or frequent temperature changes.

MACt SCC Premix is also environmentally friendly. It has been developed using sustainable materials and production methods, ensuring that it has a minimal impact on the environment. This product is also incredibly durable, which means that it has a longer lifespan than many other GFRC products. This reduces the need for frequent replacements, further reducing its impact on the environment.

Overall, MACt SCC Premix is an exceptional product that provides superior performance, durability, and ease of use. Its silica-free composition makes it a much safer product to manufacture and use than traditional GFRC products, negating most of the risks associated with processing silica-rich products. Its ability to withstand thermal shock and extreme temperatures makes it ideal for use in areas where durability and resilience are a must. Additionally, its ease of use and environmentally friendly nature make it a popular choice for contractors and DIY enthusiasts alike. If you are looking for a reliable and effective GFRC premix, MACt SCC Premix is the perfect solution.

Mixing Instructions: 

Before you start mixing, it’s important to prioritize safety. Make sure you are working in a well-ventilated area and have all necessary personal protective equipment (PPE) such as gloves, safety glasses, and a mask to protect yourself from the dust. GFRC mixtures contain fine powders that can irritate the eyes, lungs, and skin, so be sure to handle the materials with care.

Now, let’s walk through the steps for mixing MACt GFRC products:

• Step 1: Prepare Your Ingredients The first step is to ensure that you have all your ingredients properly weighed out before you start mixing. For a pourable mix, you will need water, premix, colour, plasticizer, and fibres. The exact amounts will depend on the type of mix you are making. The recommended amounts for each type of mix are listed in the guide.
• Step 2: Mix the Premix, Colour, and Plasticizer in a Separate Bucket To ensure a consistent mix, dry mix the premix, colour, and plasticizer together in a separate bucket before adding them to the water. This will help prevent clumping and ensure an even distribution of the colour throughout the mix.
• Step 3: Add 80% of the Premix Mixture into the Water Pour the premix mixture into the water, not the other way around, to reduce clumping and ensure proper mixing. Use a mixer to blend the mixture until it has a smooth and consistent texture.
• Step 4: Add the Remaining 20% of the Premix Mixture Next, add the remaining premix mixture to the water and continue mixing until you have a homogeneous mix. It’s important to scrape the sides and bottom of the bucket to ensure all the materials are mixed thoroughly.
• Step 5: Adjust the Consistency if Necessary If the mix is too thick to pour, add additional plasticizer, not water, to make the mix more flowable without reducing the overall strength. It’s essential to avoid adding water, as it will change the colour of the mix and make matching colours impossible.
• Step 6: Add Fibres to the Mix Once the mix is at the desired consistency for pouring, add the fibres and mix until you have a homogeneous mix. Be sure to mix the fibres in thoroughly, as this will help ensure the strength and durability of the final product.

 Tips and Tricks:

• Use Good Quality Mixing Gear: A high-quality mixer and other mixing equipment will ensure that your mix is properly blended and reduce the likelihood of errors and inconsistencies.
• Adjust for Temperature: In cold weather, use cold water to make the mix more flowable, but do not dry mix plasticizer as the dosage will be greatly reduced. In hot weather, cool down the mix by replacing some of the water with ice (1kg of ice and 2kg of water is recommended).
• Pour at the Right Time: In hot temperatures, pour in the cooler times of the day to give more work time before initial setting. This will help ensure that the mix sets properly and does not dry out too quickly.

By following these steps and tips, you can successfully mix MACt GFRC products and achieve the desired results. Remember to always use caution when working with any product that produces dust and to work in a well-ventilated area with appropriate PPE. With practice, you’ll soon become an expert at mixing GFRC and creating beautiful, durable concrete products. In addition to following the steps and tips mentioned above, it’s also important to use good quality mixing gear. Investing in a high-quality mixer and other tools will make the mixing process more efficient and produce more consistent results.

You can also experiment with different fibres and additives to achieve different textures, colours, and finishes. As with any new skill, practice is key, and the more you work with GFRC, the more comfortable and confident you will become in your mixing abilities. So don’t be afraid to experiment and try new things, and soon you’ll be creating stunning concrete creations that are both beautiful and strong.
