The concrete giant has a net loss of over 190 million and a debt to asset ratio approaching 70%!

by

In October 2025, the first three quarters performance announcement disclosed by Western Construction showed that the company achieved a revenue of 13.

881 billion yuan, a year-on-year decrease of 7.

57%, and a net profit attributable to the parent company was a loss of 198 million yuan, a significant year-on-year decrease of 2141.

86%.

The performance of turning from profit to loss reflects multiple pressures on the company’s management.

From the financial data perspective, the deterioration of the profit side is particularly prominent, with a weighted average return on equity as low as -2.

44% in the first three quarters and a gross profit margin of only 6.

57%, further shrinking from 8.

45% in the same period last year and far below the industry average.

Research on Factors and Countermeasures Affecting the Rebound Method for Testing Concrete Compressive Strength

by

As a commonly used method for non-destructive testing of the main structure of construction projects, the rebound method plays an important role in engineering quality supervision.

The following is a study on the influencing factors, countermeasures, and problems discovered in the supervision of engineering based on the rebound method for strength measurement.

Study on the Growth Law of Concrete Strength under Low Temperature Exposure Curing Conditions

by

For the study of the strength law of low-temperature cured concrete, Li Fen et al.

in China studied the development law of compressive strength of medium and low-grade concrete under negative temperature conditions, and fitted the relationship between compressive strength and age using a logarithmic function.

Here, the ages are 3d, 7d, 28d, and 56d.

Analyzing the mystery of the “penetration” of sealing and curing agents: how does it permanently enhance the strength of concrete?

by

In industrial floors, warehouse workshops, and other places, we often see floors that are as smooth as new and as hard as stone.

This is often attributed to a material called a sealing curing agent.

It is not like epoxy flooring that covers the surface of concrete, but rather like injecting a strong needle into the concrete, fundamentally improving its performance through deep penetration and chemical reaction with the concrete.

Reasons and solutions for air holes on the surface of concrete during aluminum formwork construction

by

During the molding process of concrete, various factors such as materials, processes, and environmental conditions often lead to the formation of bubbles on the surface of the concrete.

Plastic Rebar Chairs

A small amount of bubbles will not have a significant impact on components or buildings, but too many bubbles will bring a series of problems.

(When the air content of concrete increases by 1%, the compressive strength at 28 days decreases by 5%.

Brief Description of General Mandatory Concrete Pouring Method for Foundation (Reference)

by

First, pour the bottom foundation of the first layer of observation pier, and then determine the height of the observation pier according to the design requirements, in order to meet the design requirements, practical observation, and convenient use.

The pouring of commonly used observation piers should first be done by making wooden molds.

The inner diameter, size, and shape of the wooden molds vary with engineering or design requirements (in recent years, many places have used 200mm PVC pipes as observation pier molds).

Lifting Socket

Regardless of the mold used, the upper 10cm must be disconnected for vertical adjustment and staged pouring.

Secondly, the top plane size of the observation pier should be 3-4cm larger than the base size in order to facilitate the pouring of the second phase concrete.

The wooden formwork should be tightly fastened with Ø 16 steel bars or flat steel hoops around it to prevent deformation during pouring.

A centerline should be drawn around the wooden formwork for alignment.

To ensure the verticality of the observation pier, a theodolite, level, and plumb bob should be used for alignment during pouring.
