[Example of problem] In late January, the project supervision agency inspected a concrete structure project in Huairou District, Beijing.
At 9:30 am, it was found that the top concrete poured around 5 am only covered with plastic film, and the surface of the concrete had been frozen!.
In urban infrastructure construction, an efficient drainage system is the key to dealing with waterlogging during the rainy season and ensuring a clean environment.
Yatai Building Materials, with the core concept of “Thai Chain Intelligent Manufacturing”, has launched precast concrete drainage ditches to provide durable and convenient drainage solutions for urban, road and bridge, garden and other scenes.

Recently, the data of Chengdu’s ready mixed concrete industry in 2025 reflects the industry difficulties in first tier cities across the country.
There are 147 compliant enterprises in the city (24 state-owned enterprises and 123 private enterprises), with a total output of 41.
22 million cubic meters, a year-on-year decrease of 15%.
The capacity utilization rate is only 24%, and most enterprises are operating at half capacity or even temporarily shut down.
The industry concentration is extremely high, with 8 leading enterprises accounting for 49% of the total output, and small and medium-sized enterprises struggling to survive.

The global low-carbon transformation is forcing the construction industry to innovate.
Concrete, as the most widely used building material, has a significant proportion of carbon emissions.
In traditional technologies, high cement usage conflicts with low-carbon goals, and the use of solid waste admixtures often leads to poor construction performance, becoming a pain point in the industry.
Under the concept of green development, analyzing material characteristics, optimizing mix ratio parameters, and innovating construction control technologies can solve this contradiction.
Responding to the dual carbon strategy, providing a new path for high-quality development of concrete engineering, connecting theoretical exploration with key links in engineering practice.

In concrete construction practice, the phenomenon of adding water on site is very common and has been repeatedly prohibited.
On the one hand, it is due to the weak quality awareness of construction personnel, who add water arbitrarily for the convenience of construction.
On the other hand, the lack of workability in concrete makes it difficult to meet construction requirements, especially in today’s complex concrete structures with dense steel bars.

Sustainability and extreme environmental adaptability have always been research hotspots in the field of building materials.
Geopolymer concrete (GPC) has become an ideal substitute material for traditional Portland cement concrete (OPC) due to its advantages of low carbon emissions and utilization of industrial by-products.
Especially in special scenarios such as industrial plants and high-temperature work areas, their high-temperature mechanical properties directly affect structural safety.
This article combines experimental testing and machine learning (ML) modeling to systematically explore the variation law of compressive strength of GPC under high temperature environment, providing key technical support for its engineering application.

Previous studies have shown that adding tiny reinforcing fibers to concrete before pouring is less likely to cause cracks.
Given this fact, scientists at Washington State University in the United States want to know if polypropylene or polyester fibers in discarded masks may be the source of these fibers.

The quality of construction engineering is directly related to the quality of concrete raw materials.
Therefore, in order to ensure the quality of each link and structure of the construction project, it is necessary to ensure that the construction concrete raw materials meet the design standards and requirements.
This requires in-depth testing of the quality of concrete raw materials.
Strengthening the testing of raw materials can not only provide reference for the scientific and rational allocation of concrete, but also improve the quality of construction projects.
However, the current level of attention and research on this issue in China still needs to be strengthened.
