Three, sand and gravel aggregate industry this week dynamic
1, 2 billion 10 million yuan! 61 Fangda Mine
On 27 February, Zhejiang Communications Resources Investment Group Co., Ltd., a subsidiary of Zhejiang Communications Group, held a 16108 of the controlled resources of granite ore for construction with the mining right. In addition, the mine is adjacent to the Xijiang Golden Waterway and can be supplied to the Guangdong-Hong Kong-Macao Greater Bay Area after putting into operation.
2. Annual output of 10 million tons! The total investment is 200 million yuan! Located in Baijiagou Village, Nanzui Town, yuanjiang City, the project is invested and constructed by Hunan Lishan New Material Technology Co., Ltd. with a total investment of 200 million yuan. It mainly constructs two production lines, one with an annual output of 2.009 million tons of machine-made sand, the other with an annual output of about 5.333 million tons of machine-made sand and about
266.3 tons of machine-made sand, with an annual output of 3 million tons! The project is located in Ermen Village, Xinji Town, Nanzheng District, Hanzhong City, with a total investment of 730 million yuan. It is invested and constructed by Shaanxi Traffic Control Group. The main product specifications of the stone ore production line are stone powder, machine-made sand (0-5mm) and aggregate products (5-10 mm, 10-20 mm, 20-31. In August 2021, Shaanxi Traffic Control Group won the mining right of the project. The annual production scale of the mining right is 3 million tons, and the mining life is 15 years.
4. Comments on
the dynamics of the concrete industry this week 1. Successful application
of sea sand concrete composite reinforcement recently, during the construction of the road project of Yinggehai First-Class Fishing Port in Ledong, Hainan. The composite reinforcement made by China Railway Construction Heavy Industry Electrical Materials Co., Ltd., China Railway Construction Port and Navigation Bureau and Hunan University has been successfully applied to sea sand concrete instead of steel bars. Compared with the common steel bar, the density of the composite bar is only a quarter of that of the common steel bar, but the tensile strength of the composite bar is 2-3 times of that of the common steel bar. Due to the insulation and chloride corrosion resistance of the composite reinforcement, there is no corrosion problem or electrochemical corrosion problem when it is used in sea sand concrete. While meeting the strength and durability of concrete, the project reduces the use of river sand, reduces the cost of raw materials, effectively solves the problem of easy corrosion of sea sand concrete pavement reinforcement, and achieves good application effect.
Qinghai Traffic Control Group announced on March 1 that after 19 hours of pouring, the first pier body of No.10 pier, the highest pier of Zhamaohe Bridge on Tongsai Expressway, the first high pier of Qinghai Highway Bridge, has been successfully poured. The first pier body is 6m high and 558 cubic meters of C50 concrete is used. It is a single-box three-cell rectangular hollow pier with complex structure, great difficulty in construction and high risk in cold season. The successful pouring of the first formwork pier body has accumulated experience for the subsequent construction of the pier body and promoted the construction progress of the control project.
3. "The world's largest span 1800 type continuous rigid frame bridge with corrugated steel webs" Feilong Bridge began cantilever pouring construction
. "The world's largest span 1800 type continuous rigid frame bridge with corrugated steel webs" Feilong Bridge successfully completed the first 0 block pouring recently, and formally entered the cantilever pouring stage. The total length of Block 0 of Feilong Bridge is 19. Among them, the 0-1 section is successfully constructed with the assistance of the prestressed bracket method patented by Guangxi Road Construction Group, and the 0-2 section is constructed with the "front suspension and rear support" construction method innovatively proposed by the technical team of Feilong Bridge of Guangxi Road Construction Group. The No.0 block of No.6 main pier of Feilong Bridge was first completed. After calculation, compared with the traditional construction method, this construction method can save nearly 460,000 yuan for the construction of the cantilever end of the three main piers of the bridge, and reduce the total demand for steel 27.
5. Concrete market
this week, the national concrete price index closed at 139.76 points this week, which was flat compared with last week. Year-on-year decrease 8. Regionally, concrete prices in all provinces and cities in China remained stable. In
the next ten days, except for the cumulative precipitation of 10-25 mm in parts of southwest China, central and western Jiangnan and northwestern Guangxi, which can reach more than 30 mm locally, the precipitation in most other parts of China will continue to be on the low side, and there will be no precipitation in North China, Huanghuai and southern Guangdong. In terms of temperature, the temperature in the central and eastern part of China fluctuated, and the temperature in the early stage was significantly higher. The average temperature in the western part of Xinjiang, North China, Northeast China, Huanghuai, Jianghan and other places was 4 to 7 degrees higher, and the temperature dropped after 11 days.
To sum up, there will be less precipitation in China next week, the temperature in the northern region will rise, and the construction conditions will be improved. The capital arrival rate of downstream infrastructure projects is high, and the construction is more active, which supports the market demand for concrete. Partial sales of real estate have improved, but the development funds are still tight, and the construction progress of the project is still slow. Overall, with the resumption of production in the north next week, concrete shipments are still showing an upward trend. In terms of cost, the upstream raw material prices showed an upward trend, which strengthened the support for concrete prices. On the whole, the supply and demand of concrete market will be further improved next week, and the price is more likely to rise steadily.
