Month: January 2026

According to data analysis from the National Bureau of Statistics, the main economic indicators of the concrete and cement products industry will continue to decline from January to November 2025.

The main business income of the concrete and cement products industry above a certain scale decreased by 14.

3% compared to the same period last year, a decrease of 0.

3 percentage points from January to October; The total profit decreased by 26.

57% compared to the same period last year, a decrease of 0.

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.

Concrete mix ratio is almost a core skill that every concrete practitioner must master.

Both enterprise managers and frontline technicians are well aware that the rationality of mix proportions directly affects the quality and construction effectiveness of concrete.

In bridge construction, bridge piers serve as key load-bearing structures, and their concrete quality directly affects the safety and durability of the bridge.

In the actual construction process, the phenomenon of honeycomb and cracking on the concrete outside the bridge pier occurs from time to time.

These issues not only affect the appearance of the bridge, but may also weaken the load-bearing capacity of the structure and reduce the service life of the bridge.

It is of great practical significance to conduct a thorough analysis of the causes of honeycomb and cracking in the concrete outside the bridge pier, and to take effective remedial measures.

The Yellow River Irrigation Project of Wenbi Electric Irrigation Station in Hequ County is divided into primary and secondary pump stations and water tanks.

The project adopts C30 concrete pouring.

Due to the range of water level changes, the design requires the concrete to use a first grade, with a frost resistance grade of F200 and an impermeability grade of W4.

The maximum particle size of the aggregate is 2/3 of the minimum spacing between the steel bars, not exceeding 25mm.

This time, artificial crushed stone with a particle size of 10-20mm is used.

C80 high-performance concrete, as a building material with excellent performance, has been widely used in super high-rise buildings.

This article takes the Guangsheng Wanbo City project as an example to provide a detailed description and optimization analysis of the application of C80 high-performance concrete in super high-rise buildings.

Those who study engineering, especially civil engineering related majors, as well as those engaged in civil engineering project design, construction, supervision, and budgeting, inevitably have to deal with the word “tong” frequently.

Speaking of the word ‘concrete’, it’s a bit awkward.

Concrete is one of the most important structural materials in construction engineering, and its performance directly affects the quality and safety of the project.

Rebar Saddles

With the development of building materials technology, the performance of traditional concrete is no longer sufficient to meet the needs of modern engineering, especially in terms of high strength, high durability, and green environmental protection.

Therefore, using additives to improve the performance of concrete has become an effective way to solve this problem.

As a new type of admixture, thickening agents have received widespread attention in recent years.

Thickener can not only improve the flowability, water retention, and anti segregation of concrete, but also enhance its mechanical properties and durability, making it one of the key factors in optimizing the comprehensive performance of concrete.

The strength of concrete is the basic guarantee for the structural safety of building products, and it is also a problem that construction workers often face.

However, due to a deviation in understanding the standards, there are still errors in their application and inference in actual construction production.
