On February 27, 2026, the Concrete Admixtures Branch of the China Building Materials Federation organized an expert review meeting for the “New Developments in Research and Application of Concrete Admixtures in 2026” essay competition through video conference.

Have you ever had an experience where you finally managed to gather enough down payment to buy a house, only to be stunned by the parking price and say, “It’s just four lines and one frame.
Why is it even more expensive than my car.
Against the backdrop of the global construction industry accelerating towards low-carbon transformation, how to properly handle and utilize massive amounts of construction waste has become a core issue in the engineering industry.
This week, the authoritative institution in the field of precast components in Europe officially released the “2026 Application Guidelines for Recycled Concrete Components”, while also warming up the upcoming BIBM 2026 conference in Rome.
This marks a new stage of standardization and scale in the application of “recycled concrete” in structural precast components.

On March 10th, the national cement market was mainly declining, with some cities including Fujian and Chongqing experiencing price drops.

Recently, as the cutterhead of the No.
625 shield machine of China Railway Equipment slowly broke through the wall, the left line of the section from Jinjilu Station to Jianshe Yilu West Station of Hangzhou Metro Line 15, which was constructed by China Railway First Bureau, was accurately connected, and thus the double track tunnel of this section was successfully connected.

Due to its low tensile strength, concrete floors can be cracked by the tensile stress generated during thermal expansion and contraction.
And seam cutting is the use of manual intervention to cut horizontal and vertical seams to guide and control the location and direction of concrete cracking.

In construction engineering, the crack resistance of large volume concrete has always been a pain point in the industry – once cracks appear, they not only affect the aesthetic appearance of the structure, but may also weaken the bearing capacity, reduce durability, and even cause safety hazards.

13 sets of typical cases of special construction plans for hazardous projects (3D color images), including Bailey beam high formwork, steel structure, large-span high suspended structure formwork platform, aluminum alloy formwork support, cast-in-place box girder, tower crane installation and removal, corridor suspended ceiling curtain wall hoisting, hydraulic climbing formwork, steel mesh frame, bridge jacking, foundation pit support, earthwork excavation, cantilever scaffolding, cable tower and other special constructions.
They play a key role in eliminating major accident hazards in construction and preventing major safety risks in engineering construction, and are provided for learning and reference.

Concrete used for hydraulic structures such as dams, water gates, pump stations, embankments, bridges, culverts, etc.
is called hydraulic concrete.
The reasonable design of hydraulic concrete and strict control of its construction quality are important guarantees for the engineering quality of hydraulic structures, which are related to the safe operation of the entire hydraulic structure.
Therefore, during the entire process of constructing hydraulic structures, the quality of concrete should be tracked and tested from beginning to end to ensure that the quality of concrete used for hydraulic construction meets design requirements, is stable, and has minimal fluctuations.

On March 6th, the national cement market experienced a major decline, with prices mainly concentrated in Zhejiang province.
