Researchers have developed a “giant” using concrete, achieving the goal of “killing three birds with one arrow”
On January 30th, in Macheng City, Hubei Province, a massive object resembling a ship completed its final pressure test in the factory area of Wugang Institute New Materials Company of China Communications Second Navigation Bureau.
This is a prestressed UHPC shell cast-in-place inner core ordinary concrete composite cover beam (also known as “Ningbo beam”) independently developed by the company’s technical team.
Its successful development means that multiple global challenges in bridge construction are expected to be solved.

Application and development of foam concrete in housing construction system (I)
With the continuous deepening of China’s energy-saving and low-carbon policies and the significant improvement of people’s quality of life, the energy consumption and carbon emissions in the construction industry are increasingly receiving high attention from the whole society.
As an important carrier of energy consumption, buildings’ energy conservation and emission reduction have become one of the key links in promoting the achievement of the national “dual carbon” goals.
The heat loss caused by building envelope structures (including roofs, exterior walls, doors and windows, floors, etc.
) is the main reason for the high energy consumption of buildings.
Therefore, improving the thermal performance of building envelope structures and developing efficient and energy-saving insulation systems have become one of the core topics in global building energy conservation research.
In this context, the research and application of high-performance building envelope insulation materials is regarded as an important technological path to achieve building energy efficiency goals.

How to proficiently master the mnemonic of concrete performance for concrete workers
Concrete, as the cornerstone of the construction industry, its performance and quality are directly related to the safety and durability of the project.
For every person engaged in concrete work, mastering the performance characteristics of concrete proficiently is the key to ensuring project quality.
Today, we will bring you a “Formula for Concrete Performance” to help you understand the core points of concrete more systematically and comprehensively.

Experimental study on the bonding behavior between GFRP steel bars and ordinary and high-strength geopolymer concrete
Cement based concrete is the most commonly used material in construction, but its production process emits a large amount of CO ₂, exacerbating global warming.
Geopolymer concrete (GPC) is made from industrial waste materials such as fly ash and slag, reducing carbon emissions by 80% and possessing advantages such as early strength, corrosion resistance, and low creep.
At the same time, fiber-reinforced polymer (FRP) bars (such as GFRP) have characteristics such as corrosion resistance, lightweight, and high strength, making them suitable for harsh environments.
Therefore, the combination of GFRP reinforcement and GPC is considered a sustainable and durable green building material.

What grade of concrete is the best for self built houses in rural areas?
Considering the impact of concrete grade on the quality of self built houses, this judgment is very pragmatic.
The selection of concrete grade for rural self built houses should be based on the stress requirements of different parts.
I will give you a detailed explanation now.
