（G681 Polished star granite）

The stone number of Shrimp Red is G681, which is usually affectionately called Shrimp Red. This is a red granite mainly produced in the Nan'an Shijing area, and also produced in Zhangpu, Longhai, and other areas. It is produced in different mines. The products, minerals, and colors are different, but on the whole, it has small patterns, uniform colors, and small color differences, and can be decorated in a large area. a feeling of.

In addition, shrimp red has the characteristics of slow weathering and slow fading, which makes it not only an ideal stone for floor paving and stairs, but also can be used as a dry hanging stone for exterior walls after smooth surface treatment, which has a very good visual performance.

After inspection, the average bulk density of shrimp red is 2.57g/cm³, which is in line with national technical specifications, which proves that it is easy to cut and shape, and can be used for sawing, grinding, throwing, cutting, etc., and can create thin plates and large plates. It is made into various surface effects such as polishing, matt, fine grinding, fire burning, water jet treatment, and sandblasting; the average water absorption rate of the sample is 0.48%, which proves that it has good weather resistance and is not easily damaged by moisture. The anti-erosion, anti-weathering, the anti-freezing, and moisture-proof ability of the sample; the average compressive strength of the sample is 104.9MPa, which proves that its hardness is high and can withstand greater pressure, and can be used for dry hanging of high-end building exterior walls, curbstones, large squares The average bending strength of the samples is 11.5MPa, and the average is 9.1MPa in the water-saturated state. It can be seen that its anti-collision, anti-vibration, and anti-bending performance are strong. In addition, after inspection, the radioactive specific activities of the natural radionuclides radium-226, thorium-232, and potassium-40 of shrimp red meet the conditions of IRa≤1.0 and Ir≤1.3 at the same time, which are the A-class decoration stones specified in the standard. , the scope of production, sales, and use are not limited.

Since the 1980s and 1990s, there has been a wave of the stone craze in Nan'an, and stone village enterprises such as state-owned, township, individual, inline, Sino-foreign joint ventures, and wholly foreign-owned enterprises have competed for development. In this process, shrimp red, as a local characteristic stone, was vigorously mined and gradually became known throughout the country.

From the mid-to-late 1990s to the early 2000s, Shrimp Red sold well all over the country as a high-quality stone and was deeply loved by a vast number of real estate developers, builders, and ordinary consumers. Whether it is tooling or home improvement, the shrimp red at that time can be said to be the same as the king in the granite field. Capital Airport T2 terminal, Beijing Yintai Center... In these famous domestic projects at that time, the existence of shrimp red can be seen.

The artistic taste and original cultural connotation of returning to nature make these high-end projects wrapped in shrimp red, full of style in the vicissitudes of nature, and radiate the lasting charm of time condensed.

However, due to the popularity of local stone materials such as shrimp red and rust stone, since the 1990s, some enterprises have been greedy and savagely mining quarries, resulting in serious damage to the mountain, which not only seriously threatens the operation safety of the surrounding reservoirs, but also makes the nearby ecological chain It was severely damaged, and the surrounding people were miserable. To this end, the Nan'an government has made a serious attack and has started to rectify the mining area one after another in the past few years. Affected by this, Shrimp Red withdrew from the historical stage of the market.

Time and history have proved that shrimp red has both ornamental value and extremely high practical value and cost performance. I believe that in the future with more diversified decoration styles, Shrimp Red will have the opportunity to stage a drama of the return of the king.
