Legend has it that Go originated in Quzhou, Zhejiang Province. For this city, Go is more than a traditional game—it is a cultural treasure deeply etched into the soul of the city. During the construction of Section I of the Lanke Mountain World Go Park in Quzhou, BCEG Advanced Construction Materials Co., Ltd. leveraged its profound technical expertise to successfully and efficiently complete the concrete supply task, showcasing strong technological competitiveness in the market.

According to the project’s key personnel, the park features one of China’s large-scale acrylic light-transmitting fair-faced concrete structures, with a notably complex design. The building’s exterior walls adopt an undulating thin-shell curved surface design, with a thickness of only 120 mm. The primary inner and outer slanted walls feature continuously varying inclination angles ranging from 40° to 60°, forming a dynamic exterior and spatially intricate structure based on a circular layout. The structure also incorporates tri-color, irregular, curved fair-faced concrete surfaces. These requirements posed extraordinary demands on concrete performance, akin to the complexities of a Go game, bringing new challenges to concrete technology.

To meet these challenges, the technical team at BCEG Advanced Construction Materials Co., Ltd. swiftly formed several specialized research groups focusing on the development of durable fair-faced concrete, high-strength white concrete, and the color-matching and batching process of colored concrete. The company convened multiple technical seminars, dedicating full efforts to solving issues such as air bubbles, color variance, slump retention, cracking resistance, and durability. Eventually, the team successfully developed a comprehensive production system for fair-faced concrete, covering all aspects from raw material selection standards, mix design methodology, mixing parameters, key points for pouring and vibration, to curing schemes—providing robust technical support for the smooth progress of the project.

The project had particularly strict requirements for color consistency, demanding uniform concrete surface color with no visible color difference within 5 mm. To meet this standard, BCEG Advanced Construction Materials Co., Ltd. maintained strict control over concrete mix design and mixing processes, using raw materials of the same brand and specification, producing via a dedicated line, and continuously monitoring and adjusting the quality of freshly mixed concrete.

To control air bubbles, the technical team applied its expertise by precisely adjusting the slump and workability, ensuring adequate and uniform vibration to achieve a compact internal structure and excellent texture. In response to the high whiteness requirements of the white fair-faced concrete, technicians conducted extensive experiments and carefully developed an optimal mix using white cement, slag powder, and titanium dioxide, effectively enhancing the concrete’s brightness.

Given that the fair-faced concrete was to be poured into thin-walled, irregular curved forms, which posed high construction difficulty and a strong tendency toward cracking, the team innovatively improved the bonding between fibers and the concrete matrix. This effectively prevented shrinkage cracks during the plastic stage, significantly improving the structural stability and durability, thus ensuring the safety and quality of the entire building.

Now, Section I of the World Go Park, for which BCEG Advanced Construction Materials Co., Ltd. exclusively supplied the concrete, has been successfully completed. Since the project’s commencement, the company has delivered a total of 58,739 m³ of concrete, including approximately 4,000 m³ of original-color, white, and colored fair-faced concrete. This contribution has played an indispensable role in the city’s cultural development. The success of this project fully highlights BCEG Advanced Construction Materials Co., Ltd.’s technological strength as a state-owned enterprise based in the capital, as well as its commitment to social responsibility and its role as a model SOE.
