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.

In the construction of various projects such as buildings, municipal engineering, and roads in Changsha, selecting the right formal and reliable concrete enterprises is the core link to establish a solid foundation for project quality and ensure smooth progress of construction.
Hunan Yue Concrete Construction Engineering Co.
, Ltd.
, as a local professional concrete mixing plant operation service provider in Changsha, focuses on the full chain service of commodity concrete research and development, production, and distribution.
With stable production capacity, strict quality control, and efficient distribution system, it has become a trusted concrete cooperation preferred by engineering parties in Changsha.

The working principle of concrete mixing equipment varies.
This article only analyzes the double horizontal shaft mixing equipment with a middle storage hopper.
The working principle is as follows: firstly, a series of aggregates such as pebbles and sand are accurately calculated and measured, transported to the middle storage hopper through a conveying device, and then dropped into the mixer from the middle storage hopper.
Cement and curing agent powders are transported to the powder hopper through a screw machine, and then combined with the aggregates in the middle storage hopper; Water is accurately measured using specialized measuring tools, and the mixture mixed with some additives needs to be fed into the mixer through a transfer hopper and a conveying pipeline; Then turn on the mixer for stirring; Finally, place the finished product into the concrete transport vehicle.
