What are Concrete Chemicals and Fillers?

Concrete chemicals and fillers are important materials used in concrete applications. These materials can be applied to the concrete surface as well as to the concrete mortar. Substances that increase the functional properties of concrete are used to prevent the formation of cracks and to achieve a better surface appearance. Therefore, there are both functional and aesthetic purposes in its use. Omnis Composite offers many different products as concrete fillers and chemicals. Since each one has different features, it is possible to choose according to the areas of use. The products in question are the following:

Concrete Plasticizer: Concrete plasticizers are important chemical substances that are added to concrete mortars to regulate the fluidity of the mixture according to the desired process. In general, Flowaid FT and Flowaid SCC are used in concrete applications. Flowaid FT is a concrete plasticizer that can be used effectively in spraying and premix applications. This product, which is among concrete fillers and chemicals, makes the flowability property more efficient for the processing of concrete. Its use ensures that the concrete is evenly distributed and the surface has a better appearance.

However, it is important that the water content in the use of this product is low. Excess water can cause undesirable appearances such as stains and cracks on the concrete surface after hydration. It is therefore recommended to use a small amount of water and the optimal amount of plasticizer. Together with this polymer product, it will ensure even curing of the concrete and prevent the formation of cracks and stains in the best way. The use of this product, which is among these concrete fillers, should be adjusted according to the ambient temperature. Therefore, care should be taken to use it in accordance with the temperature instructions in the prescription. It is generally recommended to use less in winter and 2-3 times more in summer. Another important consideration is that the polymer and plasticizer work in harmony. The product instructions must therefore be strictly followed.

Acrylic Polymer: When used with Polycure FT and FT EXtra, it evaporates the water needed for curing from the concrete mix and thus prevents its escape. It also ensures homogeneous curing of the concrete. This product forms a thin film in the cement mortar. This ensures that the moisture required for full hydration is retained and helps the concrete to cure evenly. It provides surface smoothness, waterproofing and strength of concrete in thin GRC applications. The preparation of acrylic polymer material is quite simple. It is added to the water addition in the mortar prepared before use. It is then applied by adding plasticizer sand and cement. It offers a perfect solution in terms of color, pigment and appearance.

If we need to mention the ideal usage rate, we can state that it is 10% of the cement added to the mortar. This is because the smooth surface, strength and water impermeability quality are best realized in these ratios. In cases where an acrylic curing product is not used, natural methods can also be used. For this purpose, the GRC piece is covered with a nylon cover and water is supplied at regular intervals. This is called wet curing and is a laborious process that requires labor. There is also a risk of reducing the durability of the product.

Mold Release Agent for Concrete Applications: Mold release agent for concrete applications is used to obtain high performance concrete surfaces. These separators are applied to the mold surfaces before the concrete pouring process starts. Its intended use allows the formwork to be easily separated from the concrete. This product improves the efficiency of the mold while giving a smooth and spotless surface. This also has the effect of extending the service life of concrete. In cases where mold release agents are not used, eyelet cavities, holes and unwanted pigment formations are observed on concrete surfaces. These products prevent all these appearance defects in concrete.

Polyurethane Mold Silicone: Polyurethane elastomers are used in applications such as plaster, pad printing prototype design, polyester, plaster, shoe sole molding. It enables to obtain a variety of products with transparent, semi-transparent and required mechanical properties according to the areas of use. It is a method that enables silicone molding to be made. This product is characterized by being durable, flexible and easy to use. Since it is used in mold making, it plays an important role in the creation of a new product. It has high chemical resistance as well as flexibility and durability. It therefore helps in producing shaped and flat molds in various fields.

Micro Silica-Silica Ash-Fume: This product stands out when it comes to concrete chemicals. The product contains a high proportion of amorphous silica and consists of very fine spherical particles. If the silica fume in the cement exceeds 5%, it is important to use it under certain conditions. The proportion of amorphous silica (SiO₂) must be greater than 85% by mass. It is also important that the combustion loss is less than 4% of the mass and the specific surface area is greater than 15 m²/g. This fine-grained material reduces the workability and consistency of concrete. This in turn increases the need for water.

This material among concrete chemicals, which is generally gray in color, consists of nano-sized powders. This product fills the gaps between larger cement grains. This ensures a more dense structure. If applied over a very large surface area, more water is required. Therefore, if it is to be used on large surface areas, a plasticizer should be used. In European countries, concrete is produced using this material.

Dried Silica Sand AFS 30-35: Dried silica sand, one of the concrete chemicals, is one of the building blocks of the construction industry. Its most important feature is its high moisture absorption. It is therefore possible to use it for different applications in various fields.

Expanded Glass(Stikloporas): Stikloporas, which is among concrete chemicals, is used in applications such as insulation plasters, insulation panels, lightweight concrete block, floor leveling.

Color Fillers: Products containing pigments that change or customize the color of concrete. They are used for aesthetic purposes and are popular in architectural projects.

Super plasticizers: They work in a similar way to plasticizers, but provide a higher rate of water reduction. These products are important for producing high-strength concretes.

Corrosion inhibitors: They are used to minimize the corrosion rate of steel and steel bars in concrete.

What is it used for?

Concrete chemicals and fillers are substances used to improve the durability, mechanical properties and workability of concrete. They are used for different purposes such as reducing water permeability, increasing durability, changing color or appearance, improving workability. They can also be used to regulate thermal properties or improve resistance to environmental influences. Concrete chemicals and fillers are widely used in the construction industry to improve the quality and performance of structures. These materials, which are used in different sectors, make a great contribution to structures, especially in terms of durability.
