HD-RSJ black concrete stain

 

I. Product Overview

HD-RSJ concrete dye is a powdered material whose crystal structure and chemical properties enable it to absorb and reflect light of specific wavelengths, thus presenting rich colors. Pigment particles can be quickly and evenly dispersed in concrete, and are tightly combined with cement hydration products. They are fixed inside the concrete structure through physical filling and chemical adsorption, achieving a lasting dyeing effect. In addition, HD-RSJ dye can form a strong interface bond with the cement matrix, effectively improving the tensile strength and crack resistance of concrete and enhancing the durability of concrete. The multi-component synergistic design of HD-RSJ dye enables this concrete dye to meet the needs of color decoration while ensuring the physical and mechanical properties and long-term stability of concrete. The product complies with the requirements of GB 175-2023 "General Portland Cement", GB 8076-2008 "Concrete Admixtures", GB/T 1863-2008 "Iron Oxide Pigments", GB/T 12988-2009 "Test Methods for Wear Resistance of Inorganic Ground Materials", GB/T 50081-2019 "Standards for Test Methods for Physical and Mechanical Properties of Concrete", and GB/T 50082-2024 "Standards for Test Methods for Long-term Performance and Durability of Concrete".

2. Scope of Application

1. The construction of colored concrete pavements of various municipal roads and squares adds bright colors and unique features to the city.

2. The dyeing decoration and performance enhancement of concrete structures such as sidewalks and landscape sketches in parks create a beautiful environment.

3. The color beautification and durability improvement of concrete in pedestrian paths and leisure areas in residential areas improve the quality of living.

3. Main technical performance and characteristics

1. Good dispersibility: The product has a uniform and fine texture and can be well dispersed in concrete to ensure uniform and consistent dyeing effect.

2. Strong coloring ability: It can make concrete obtain a bright and lasting color effect, effectively improving the beauty and decorativeness of concrete.

3. Good weather resistance: The iron oxide pigment contained is of excellent quality and high stability, which can provide reliable dyeing guarantee for concrete and maintain the color for a long time.

4. Good stability: It is not easy to fade and precipitate under high temperature and high humidity.

5. Good adaptability to concrete: It has no adverse effect on the normal performance of concrete.

6. Moderate oil absorption: It can ensure good dispersion of pigments in concrete, and will not excessively absorb moisture and admixtures in concrete, so as to maintain stable concrete performance.

7. The pH value is in an appropriate range: It is well adapted to the alkaline environment of concrete and does not cause chemical reactions to interfere with the hardening and long-term performance of concrete.

IV. Usage and precautions

1.According to the required color depth and specific engineering requirements, accurately determine the proportion of dye added to concrete, and ensure that the mixing process is sufficient and uniform, so that the dye and concrete materials are completely integrated.

2. The raw materials of concrete must meet the relevant quality standards. Before mixing, be sure to ensure that the mixing equipment is clean and free of impurities to avoid affecting the dyeing effect and concrete quality.

3. It is recommended to use a forced mixer during construction. First, mix the cement, aggregate and other dry materials of the concrete evenly, then add the dye and continue to mix, so that the dye is evenly dispersed in the dry materials, and finally add water according to the mix ratio for wet mixing until the concrete color is uniform and the working performance is good, reaching the ideal construction state.

4. The mixing time should be reasonably adjusted according to the actual situation to ensure that the dye can fully play its role and the various properties of the concrete meet the standards to ensure the construction quality.

5. The specific dosage must be accurately confirmed through the concrete trial mix experiment to prevent poor dyeing effect or concrete quality problems due to improper dosage.

6. When adding black iron oxide, the proportion is generally 2% to 4% of the cementitious material. It is necessary to fully mix and mix to ensure uniform color.
