Technical Analysis Of Stone Products

In today's decoration market in the world, natural stone has become the main force in the architectural decoration market. People think that stone is more and more important as a building material or constituent element in a building. Stone can be used as a variety of building components to reflect each other inside and outside the building, playing an important role. Starting from the two major types of stone, marble and granite, which are widely used, we analyze the technical characteristics and application fields of natural stone, and conduct an in-depth analysis of the market prospects of building stone from the perspective of sustainable development.

Because the origin of stone is different from the geological conditions in the formation process, a variety of rocks with different compositions are formed in the natural formation process, which has the characteristics of rich reserves, wide distribution, dense structure, and high compressive strength. , The compressive strength of most stones can reach more than 100 Pa, and the durability and abrasion resistance of natural stones are very good. The stone resources available for architectural decoration in China are very rich, mainly marble and granite. The country has a proven reserve of 300 billion cubic meters and a complete variety of colors. There are more than 300 varieties of marble and more than 1,000 granite. Varieties.

The main producing areas of marble in China are mountainous areas in Dali, Shandong, Guangdong, Fujian, Liaoning, Hubei and other regions in Yunnan. The brilliant colors and bizarre patterns of the marble can be recognized after polishing. It can be used as a high-level finishing material and used in monumental buildings or buildings with high decorative requirements. Decorating hotels, cinemas, shopping malls, stations, etc. with marble has become a fashion and trend. Since the building does not make specific regulations on the strength, water absorption and durability of decorative facing materials, only the appearance quality, gloss and color pattern are used as the main evaluation and selection indicators. The inconsistency in the production, price and quality of Chinese marble has caused some unreasonable use of decoration, and the demand for construction has also brought some wrong signals to the market, resulting in the waste of many valuable resources of marble.

The content and origin of granite in my country are also very rich, mainly distributed in eastern China such as Shandong, Anhui, Fujian and other places. In addition, a large amount of granite is also found in Henan. It can be said that granite is a widely distributed building material, but due to its high specific gravity, difficult mining and transportation, processing, repairing and paving construction are time-consuming and laborious, and the project cost is high. Therefore, its use range is smaller than marble.

Granite products still play a very important role in large and important buildings. Generally, rough grinding boards are used for walls, steps and other places in buildings. Polished boards are mainly used for indoor walls because of their bright colors and high gloss. , Ground and cylinder. The leftover material from the processing of granite is also used to pave courtyard paths with pebbles and slabs. The color of the stone itself is used to achieve a harmonious unity between the material design and the environment.
