Difficulties and Countermeasures in Crack Resistance Quality Control of Ultra long Concrete Structures
The basement is a monolithic structure with a length of 570m in the east-west direction and 220m in the north-south direction.
One of the major difficulties in quality control of this project is to ensure that the concrete of the ultra long components does not crack through technical measures.

The difference and relationship between water cement ratio and slump of concrete!
The water cement ratio and slump of concrete are common problems encountered in construction projects.
Regarding the relationship between the two, most migrant workers and even some construction technicians, as well as some of our supervisors, are not very clear.
They think that a high water cement ratio means a high slump, and a high slump means a high water cement ratio.
They believe that the two are the same thing, but in fact, they are not.
There is a fundamental distinction between these two, but they are also interrelated.
To illustrate this issue, we need to start with the mix design of concrete.
Taking weight ratio as an example, the calculation sequence of mix ratio is as follows:.
Why does the United States like to recycle our country’s waste concrete, and what do they do with it? We recycle 100 million tons a year?
Various fields in our country are flourishing, with high-rise buildings and bridges rising from the ground, forming a beautiful landscape.
Concrete is widely used in construction, and in the process of modern industrial development, it also causes a certain amount of waste concrete and building materials.
According to statistics, by 2035, the amount of construction waste in China will exceed 3 billion tons.

On the 17th day of the Chinese New Year, free sharing of recruitment and job search information to help more concrete workers in need!
You can integrate others, which means you have the ability to be integrated by others, which means you have value.
No one works with anyone, it is a cooperative relationship that achieves mutual success and mutual benevolence, which can create new miracles.
Collecting and organizing information is not easy, I hope you have liked, bookmarked, and forwarded it!.
Handbook for Prevention and Control of Common Quality Problems in Construction Projects in Sichuan Province (Civil Engineering Section)
The manual focuses on common quality issues in civil construction of building engineering, and summarizes key problems such as leakage and cracking.
It uses a visual display of the problems with illustrations and text, analyzes the causes of the problems, and proposes prevention and control measures.

The concrete mix ratio is calculated by a qualified laboratory and determined after trial adjustment.
The concrete mix ratio should be the weight ratio.

One month after the implementation of tax reform, a guide for concrete enterprises to avoid pitfalls, and a core response plan for the 13%
Let’s first clarify a core fact: since the implementation of Announcement No.
10 of 2026 by the Ministry of Finance and the State Administration of Taxation, there has been no transition period, no buffer period, and no special subsidies.
General taxpayers in the national concrete industry have completely bid farewell to the 3% simple tax calculation and entered the era of “hard constraints” of 13% general tax calculation.
This is not a policy adjustment, but the beginning of industry reshuffle.
Companies that cannot keep up with the pace will only be gradually eliminated.

The total investment exceeds 32 trillion yuan! Major investment plans for projects across the country have been released! Concrete demand is
Major project construction is the “ballast stone” for stabilizing economic growth, and also the “strong engine” for promoting high-quality economic development, playing a crucial role in the economic development of various regions.
As an important pivot of economic development and a key lever for high-quality development, its strategic value and practical significance are particularly prominent.
