Cement Fondue: A Unique Blend Of Concrete And Art

Cement Fondue, also known as Ciment Fondu, is a type of cement that is widely used in sculpting and construction due to its unique properties. It is known for its extreme hardness and quick-setting capabilities, making it ideal for creating detailed sculptures and large outdoor projects. One of its key advantages is its resistance to acid corrosion, which is superior to that of Portland cement. It is also a refractory cement, meaning it can withstand much higher temperatures than normal cement, which makes it suitable for building bread ovens, barbecues, and other high-temperature applications. Additionally, it has good resistance to cold temperatures and freeze-thaw cycles, making it versatile for a range of environmental conditions.

Cement fondue is a quick-setting sculpting material

The advantages of using cement fondue include its resistance to acid corrosion, its ability to withstand higher temperatures than normal cement, and its suitability for large outdoor projects due to its durability and cost-effectiveness. It is also versatile and can be used alone or mixed with other materials.

When used on its own or as a hydraulic binder base for specialty concretes, cement fondue exhibits excellent resistance to heat, thermal cycles, and abrasion. It does not release lime during hydration, giving it good chemical resistance to acid corrosion and a large number of aggressive substances.

In refractory applications, cement fondue is primarily used for concrete insulation and can withstand temperatures up to 1,250° C when combined with suitable aggregates. It is also used in formulated products in building chemistry, such as a reagent or as the main binder for products like fast-setting mortar, tile adhesive, and self-levelling products.

The process of creating a sculpture using cement fondue involves mixing the powder with water to create a creamy slurry, which can then be applied to a mould. For outdoor use, fine silica sand is added to the mixture. The slurry is applied to the mould in sections, coating it evenly to a thickness of about 1.5mm. The standard cement fondue mix, consisting of one part cement fondue, two parts sand, and one part water, is then pressed into the mould, absorbing some of the water from the slurry layer. This mixture should be firm and not impressionable by a finger.

To reinforce the cast, a layer of fibreglass mat is dipped into the slurry and worked into the fibres before being laid into the mould. More slurry is brushed on, and a final layer of the stiff cement fondue mix is pressed on top, resulting in a thickness of about 13mm. The mould is then left to cure for 24 hours, as cement fondue sets through curing rather than drying and must be kept wet until completely hard.

Cement fondue is an excellent material for sculpting and casting due to its quick-setting properties, extreme hardness, and ability to withstand high temperatures. It is a versatile material that can be used in a variety of applications and provides superb detail in sculptures.

It is a refractory cement, withstanding high temperatures

Cement fondue, also known as ciment fondu, is a type of cement that is widely used in sculpting and other applications due to its unique properties. One of its key characteristics is its ability to withstand high temperatures, making it a refractory cement.

Cement fondue is a high alumina casting cement that achieves its full strength within 24 hours and has a working time of approximately 2 hours. It is known for its extreme hardness and quick-setting properties, making it ideal for creating detailed sculptures and large outdoor projects.

The cement's resistance to high temperatures can be attributed to its composition. It is a calcium aluminate-based product, often used as a hydraulic binder base for refractory and specialty concrete. This technology, known as Fondu Technology, offers high-added-value solutions to clients. The use of calcium aluminate provides improved resistance to heat, corrosion, and abrasion.

In refractory applications, cement fondue is primarily used for concrete insulation. When combined with suitable aggregates, it can withstand temperatures up to 1,250° C. This makes it suitable for building bread ovens, barbecues, and other high-temperature applications.

Additionally, cement fondue exhibits excellent chemical resistance due to its unique hydration properties. Unlike Portland cement, it does not release lime during hydration, resulting in better resistance to acid corrosion and a wide range of aggressive substances. This property, along with its quick-setting nature, makes it a preferred choice for tradesmen in rapid-sealing work and minor repairs.

In summary, cement fondue, or ciment fondu, is a specialised cement valued for its ability to withstand high temperatures, making it a refractory cement. Its quick-setting nature, extreme hardness, and resistance to corrosion have led to its widespread use in sculpting, construction, and refractory applications.

It is more resistant to acid corrosion than Portland cement

Cement fondue, also known as Ciment Fondu, is a fine high alumina casting cement that is widely used by sculptors due to its quick-setting properties and ability to produce superb detail. It is ideal for both casting and sculpting and is commonly used for large outdoor projects, such as decorative wall surfaces.

Cement fondue is known to have better resistance to acid corrosion than Portland cement due to its unique chemical composition. Unlike Portland cement, cement fondue does not release lime during hydration, which gives it improved chemical resistance to acid attacks. This property makes it suitable for use in sewer systems and agricultural environments, where it can protect against corrosion caused by acids and bacteria.

The higher resistance to acid corrosion in cement fondue can be attributed to its ability to retain stable hydration products in an alkaline pore solution. In contrast, Portland cement is more susceptible to acid dissolution, as the calcium hydroxide in its composition reacts with the acid solution. This reaction leads to the degradation of the cement paste and a decrease in the stability of its hydration products.

Additionally, cement fondue has a higher Si/Ca ratio, which refines the pore structure of the cement paste, further enhancing its resistance to acid attacks. The refined pore structure makes it more difficult for hydrogen ions to penetrate and cause corrosion.

The improved acid resistance of cement fondue makes it a preferred choice in applications where protection against acid corrosion is crucial, such as in sewer systems and agricultural buildings.

It is suitable for outdoor projects and decorative wall surfaces

Cement fondue is a suitable material for outdoor projects and decorative wall surfaces due to its durability, quick-setting properties, and resistance to the elements.

Its durability is a result of its high alumina content, which also contributes to its hardness and toughness. These qualities make it ideal for creating sculptures and decorative wall surfaces that require intricate details and unique designs.

Additionally, cement fondue is highly resistant to heat, thermal cycles, and abrasion. This makes it suitable for outdoor projects, as it can withstand varying temperatures and weather conditions. It is also resistant to acid corrosion and aggressive substances, ensuring its longevity in outdoor environments.

The quick-setting nature of cement fondue is advantageous for outdoor projects and decorative wall surfaces. It allows for faster construction and completion times, reducing the overall project duration. This is especially beneficial for projects with time constraints or those requiring rapid repairs.

Furthermore, cement fondue's versatility in application methods, such as casting and sculpting, provides artists and builders with greater freedom in their creative processes. They can utilise techniques similar to those in the building industry, enabling the creation of large-scale concrete sculptures and decorative outdoor features.

Overall, cement fondue's durability, quick-setting properties, resistance to heat and corrosion, and versatility make it a suitable choice for outdoor projects and decorative wall surfaces.

It is used as a reagent in formulated products

Ciment Fondu is a versatile and resistant product that can be used alone or mixed with other substances. It is a type of calcium aluminate cement, which is a quick-setting and extremely hard material. It is widely used by sculptors and for building applications.
