FROM MATERIALS TO INFRASTRUCTURE, TRANSFORMATION AND UPGRADING UNLEASH NEW MOMENTUM

By 2021, CWCG has won 6 national projects, 42 provincial and ministerial projects, 75 international advanced scientific and technological achievements, 181 authorized invention patents, 433 authorized utility model patents, 82 provincial and ministerial science and technology awards, 23 provincial and ministerial construction methods and participated in more than 60 national, industry and local standards ...

It is understood that the company focuses on concrete industry and industrial chain extension, Internet collaboration and other key directions to carry out technical research and application. In the research, development, production, transformation and application of concrete materials, CWCG has always been committed to promoting the green and intelligent development of concrete. A series of products such as super high-rise pumping concrete, high-strength concrete, high-performance concrete, ultra-high-performance concrete, low-heat low-shrinkage concrete, high-strength lightweight aggregate concrete, fair-faced concrete, self-compacting concrete, foam concrete and radiation-proof concrete have been independently developed. They have been applied in many landmark projects such as Tianjin Building 117, Wuhan Greenland Center, Wuhan Center, Wuhan Station of Wuhan-Guangzhou High-speed, Wuhan East Lake Passage, Chengdu Shuangliu International Airport, and the Great Mosque of Algiers. The company has set a new record in the concrete industry and always run at the forefront of the industry.

In terms of industrial chain extension, CWCG has independently developed a series of products around the key control material support business of concrete materials and products, including various kinds of high-performance functional polycarboxylate superplasticizers (such as super-high-rise pumping superplasticizers), admixtures such as viscosity control and pore structure optimization, special high-efficiency early strength agents for prefabricated components, water-based release agents, and infrastructure additives, with the ability to provide in-depth synergy from products to services to comprehensive solutions.

 SMART FACTORY DRIVES INDUSTRY PRECISION PRODUCTION

In the aspect of Internet collaboration technology, research on intelligent manufacturing has been carried out. In order to realize the intelligent transformation of manufacturing and lead the industry change, key technical research has been carried out such as image, character recognition technology and automatic detection of concrete specimens, and software products and intelligent equipment such as the industry's first quality management information system and intelligent laboratory system have been independently developed.

CWCG has participated in many major infrastructure projects, such as marine engineering, bridges and tunnels, subways, airports, etc. The key technical problems of major projects, such as super-long, super-thick, super-slow-setting, have been overcome one after another.

 NEW BREAKTHROUGH IN CONCRETE TECHNOLOGY FROM THE PERSPECTIVE OF SUPER HIGH-RISE BUILDING DEVELOPMENT

The new breakthrough of concrete technology in super high-rise buildings

In recent years, with more and more super high-rise building projects, super-high pumping concrete technology has become one of the key technologies in modern building construction. In the process of concrete high-pressure pumping, many problems such as pump blockage are easy to occur, which has always been a big problem in concrete construction. Super-high-rise pumping concrete is commonly known as "glutinous rice dumplings" in the industry, which is characterized by its great fluidity. With the development of the city, CWCG has pushed forward the technology of pumping concrete in super high-rise buildings. The company has successively participated in the construction and tackled the key problems of nearly 50 super-high-rise buildings with a height of over 200m, of which nearly 10 are over 400m, and has achieved a series of leading key technological breakthroughs at home and abroad around concrete for super-high-rise buildings, creating a number of world records. Among them, the pumping height of Tianjin Building 117 reached 621m, setting a Guinness World Record (September 8, 2015).

In the Great Mosque of Algiers, with the outstanding technical advantages of ultra-high pumping concrete, the preparation technology of ultra-early strength, low heat and ultra-high pumping concrete was developed under the circumstances that the environment, the quality of floor materials and the management mode were quite different from those in China, and the technical difficulties such as ultra-early strength, high strength, ultra-high pumping and low hydration heat were overcome. In North Africa, the concrete with the compressive strength of 99MPa for 28 days was pumped to 250m for the first time (March 11, 2017), setting a new record for local concrete application strength and pumping height. The tallest building in Africa that "Made in China" fully demonstrated the hard strength of “China Construction”.

SCIENTIFIC AND TECHNOLOGICAL INNOVATION ACCELERATES THE REALIZATION OF THE "DOUBLE CARBON" GOAL

As an engineering building material, concrete is the most widely used in construction projects. CWCG actively explores the breakthrough of intelligent manufacturing technology of concrete ready-mixed plant, and puts forward the concept of "Smart factory" which takes the customer as the core, deeply blends the whole process and elements of concrete with the new generation of information technology, and integrates intelligent construction site, intelligent logistics, intelligent manufacturing and intelligent management.

In order to realize the "carbon peaking and carbon neutrality" of building materials industry, CWCG responded to China’s sustainable development strategy, boosted the green development, and made a series of corresponding plans. As early as 2009, the company put forward the construction concept of "garden factory station". It actively responds to the "carbon peaking and carbon neutrality" by leading the building of a new development pattern.
