12.55M with weight of 1,854 tons.
The Longest Precast Box Girder in China
The largest island-land liaison box Girder project in the world.
Zhoushan Sea Bridge
Zhoushan Sea Bridge is the Largest transportation infrastructure project in China.With a total length of 48.16 kilometers and a total investment of about 10 billion RMB. The box girder is the longest and heaviest whole-hole prefabricated box girder in China, with 70 meters length, 4 meters high.
Concrete Technology we have supported:
The Longest Setting Time in China
Hangzhou Metro Line 9
The total length of the line is about 16.939km, all of which are underground lines. The main foundation pit of gentian Road Station is divided into four foundation pits to organize construction. At the same time, river diversions, bridge demolition and reconstruction are interspersed with each order, and the foundation pit construction and bridge construction have a great influence on each other.
Concrete Technology with KZJpoint RR8415:
More than 65hrs Setting Time with C35, Slump of 200mm ± 20mm, Ground water contains salt, which has the effect of early strengthening and slump retention.
The Shortest Surfacing
Finishing Time in Precast Concrete, China
The Longest Set Retarding Time Concrete, China
The Largest Turning Continuous Beam Concrete, China
Construction Time: Year 2016
Guiyang Flower Orchard Twin Towers project consists of two towers, the east tower with 406m of structure height and the west tower with 345m of building height, and the total construction area of the two towers is about 827,000 square meters, with a total investment of more than RMB 10.6 billion yuan.
1. Hight pump pressure: extremely high pumping height (345m)
2. Solving the high viscosity problem in C90 concrete
3.Making the tailored formula of our concrete admixture with the poor aggregate materials (complex and changeable mechanism mountain sand) to make the concrete pumping 345m without bleeding and separation
It generally runs from north to south, connecting important groups such as Siming District, Huli District and Jimei District, which radiates northward from the xiamen island inside to Xiamen island outside by a cross-sea rapid connection. It consists of more than 20,000 ring segments and approximately 140,000 m³ of concrete. The project requires the surface finishing time of the concrete within 120 mins. by developing an early-strength polycarboxylate acid superplasticizer compounding with the set accelerator, KZJpoint RA8206 effectively solves the problem of surfacing finishing time of the segment at a low temperature environment. At the same time, the problems of poor thixotropy, high viscosity, and bubbles on appearance were successfully solved too.
Guiyang Xintiandi Civil Air Defense Project is located in Guizhou Military District, Guiyang City, Guizhou Province, China The air defense tunnel root used C120 steel fiber pumped concretes.
It has a main line length of 307.9 kilometers, and constitutes the main channels of the 'three vertical-horizontal' intercity rail transit network in Shandong Province. The beam length of the swivel segment of Zibo Super Bridge is 2-(31m + 31m), the swivel angle is 32°20' with 4.200tons of swivel weight and the swivel structure is a center load swivel.
It has high requirements for concrete durability (The liquid nitrogen storage tank at -196°C), design strength C55, impermeability level P12, frost resistance grade F30 (the mass loss rate after 300 freeze-thaw cycles is 0.71% and the strength loss rate is 3.2%), which all meet the design requirements.
F300 of concrete frost grade, P12 impermeability grade, 16 ~ 18hrs setting time, 4.0% ~ 5.0% Air content, 5hrs Slump Retention
