News - What kind of material is travertine?

Material introduction

Travertine, also known as tunnel stone or limestone, is named so because it often has numerous pores on the surface. This natural stone has clear texture and a gentle, rich quality, which not only originates from nature but also transcends it. Therefore, it is one of the rare stones used for high-end decoration of both indoor and outdoor buildings.

Common parameters

The holes of the travertine should not be too dense, the diameter should not be greater than 3mm, and there should be no transparent holes. The water absorption rate should not be greater than 6%, and it should not be greater than 1% after adding a waterproof surface layer. Freeze-thaw coefficient should not be less than 0.8, not less than 0.6. The strength of the travertine is low, and the stone village of the plate should not be too large, and should generally be controlled within 1.0 m2.

Design considerations

Travertine is a sedimentary rock with low strength, high water absorption and poor weather resistance, so it is not an ideal material for stone curtain wall panels. However, the unique texture, color and style of travertine make architects like to use them as stone curtain walls. Therefore, how to select travertine stone panels and ensure safety to the greatest extent is a very important issue. There should be no cracks in the stone slabs, nor can they be broken, and the broken slate slabs should not be glued to the wall. Travertine slabs should be free from weak streaks and weak veins. Each batch of travertine used for curtain walls should be tested for flexural strength, and the test value should meet the requirements of national industry standards. Travertine composite aluminum honeycomb panel is the best choice for stone curtain wall.

Product performance

1. The lithology of travertine is uniform, the texture is soft, it is very easy to mine and process, the density is light, and it is easy to transport. It is a kind of building stone with a wide range of uses.

2. Travertine has good processability, sound insulation and heat insulation, and can be used for deep processing.

3. Travertine has fine texture, high processing adaptability, and low hardness. It is suitable for carving materials and special-shaped materials.

4. Travertine is rich in color, unique in texture, and has a special hole structure, which has good decorative performance.

Product surface technology

In order to maintain the original texture and texture of the travertine, it is generally divided into polished surface, matte surface and natural surface without excessive processing.

When used indoors, the surface is usually polished and the surface cavity is filled with glue to keep dust out. Building facades are rarely used for reasons: 1. High price, 2. The surface is hollow and inconvenient to clean.
