"Eco-Serben" is an environmentally friendly ceramic aggregate made from resource recycling. It is a ceramic aggregate characterized by uniform components and quality, using only TOTO's sanitary ware as a single raw material, unlike blended ceramic aggregates that mix ceramics, insulators, tiles, and electronic component ceramics discharged from general ceramic production areas. It is a high-quality ceramic fired at a high temperature of 1,200°C, ensuring very stable quality. Please consider "Eco-Serben," a highly environmentally compatible material with quality suitable for infrastructure development, high durability, and diverse properties. 【Features】 ○ High hardness and high weather resistance ○ Wear resistance and corrosion resistance ○ Heat resistance and chemical resistance ○ Temperature reduction effect (action) For more details, please contact us or download the catalog.

"With Ritamate CJ, all issues related to joints and design are resolved!" It has a proven track record in sites such as bridge construction, reverse casting methods, and semi-underground tunnel construction! It has also been adopted for the washout finish of concrete building exterior walls! Ritamate CJ can create a uniform washout surface that is completely different from conventional techniques. It can be performed easily and quickly without requiring special skills or expertise. <Features> - No uneven application of chemicals, and laitance is removed at a uniform depth. - The agent does not flow on vertical or sloped surfaces, allowing for safe use. - The effect of the agent lasts for a long time even with the formwork set after concrete placement. - Uses a chemical that is less affected by rainwater and bleeding water. *For more details, please download the catalog or contact the relevant department directly.

Granufin is a general term for spherical granules made from Carbofin, Filofin, and Colorfin (powder pigments) sized approximately 100 to 300 μm. - Because they are granulated, there is extremely little dust. This significantly reduces dirt on clothing, equipment, and the surrounding environment, improving the working conditions. Additionally, they can be mixed into concrete smoothly during application. - High bulk density. They are less likely to clump, allowing for long-term storage. With a high bulk density, they occupy half the space (compared to powder pigments), saving storage space. - High coloring power. They are solidified with surfactants (similar to concrete admixtures) during granulation, making them easier to disperse within the concrete. This allows for a reduction in the amount added. - Excellent fluidity. They do not cause bridging, making measurement easy. They also do not stick to the container during application!
