The Three Gorges Dam is composed of concrete, metal structures, etc.
The quality of concrete determines the lifespan of the dam.
After multiple analyses and discussions, technology experts have unanimously decided to develop a special type of concrete for the Three Gorges Dam.

After the analysis and design of concrete structures by STRAP is completed, it is usually necessary to convert to the reinforcement details of beams in the STRAP/BEAMD module.
BEAM Drawing is an independent design module of STRAP software, mainly used to provide detailed reinforcement drawings for concrete beams.

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!.
To ensure the stable and controllable quality of concrete production, the core lies in the two major links of “precise measurement” and “uniform mixing”.
The following is a comprehensive quality control measure that covers the entire process, which can serve as a basis for internal management and disclosure of the mixing plant:.

There are many types of concrete water reducers in China, but only polycarboxylate high-performance water reducers have particularly obvious advantages.
They have high water reduction, low slump loss, low dosage, non retarding, and are not affected by dosage time.
The water reduction rate is generally above 35%, and the dosage is extremely low, only about 0.
6% to 1.
2% of the total amount of cementitious materials.
After being added to concrete, it can endow concrete with good fluidity, high strength, and low shrinkage rate, and can also reduce the occurrence of alkali aggregate reaction to a certain extent, improving the durability of concrete.
Therefore, becoming a product representing the most advanced technology of concrete admixture materials is the focus of research and development of chemical admixtures.

Industrial solid waste accumulates into mountains, and the durability of concrete encounters bottlenecks.
The “dual carbon” goal has become an industry must answer question – how to turn billions of tons of industrial solid waste into treasure?.
1.
What should be done when the raw materials cannot be immediately stopped and the supply of concrete cannot be interrupted?.
This standard is applicable to radiation protection concrete used in radiation protection engineering.
The method for determining the bound water content in radiation resistant concrete is specified.
