reinforced concreteThe reinforced concrete referred to a structure made of concrete reinforced with steel bars. Its main bearing components were made of reinforced concrete, including thin-shell structures, large template cast-in-place structures, and buildings built with slipforms and lifters.
The concrete is made of cement, sand, stones and water, as well as blending materials and adjectives in a certain proportion. After solidifying, it has a good compression ability, but its tension ability is poor, and it is easy to break due to tension. The steel bars had a strong ability to withstand tension, so a certain amount of steel bars were added to the area where the concrete was being pulled or the corresponding parts, so that the two were bonded into a whole to bear the external force together.
Reinforcement concrete had many advantages, including sturdiness, durability, good fire resistance, good integrity, good moldiness, less steel consumption and lower cost than steel structures.
In terms of lifespan, its lifespan was almost infinite in theory, but in reality, it would be affected by factors such as weathering, erosion, load bearing, earthquakes, and so on. According to different specifications of reinforced concrete, the strength of reinforced concrete for temporary buildings was not high, and the life span was more than two years, but it was easy to be damaged. The life span of structural components that were easy to replace (such as non-bearing walls) was 25 years, and the quality would gradually decrease after the time limit was exceeded. The life span of ordinary house structures was 50 years, and the life span of special steel-concrete structures such as super high-rise buildings and bridges was about 100 years. However, it was not necessary to dismantle it after reaching the design life. Instead, it was necessary to examine its safety before making a decision.
In terms of reinforced concrete related products, there are various kinds of adjectives such as softening agents, peek ether Rheological Agents, glue reducing agents, etc., as well as structural forms such as reinforced concrete joists. Joists are mostly used for roof frames, towers, etc. The tension bars often crack under the use of load, so they are only used in situations where the load is light and the span is not large.(After the development of pre-stressed concrete technology, pre-stressed concrete joists are mostly used for large-span and heavy-load joists.) In terms of steel for reinforced concrete, the standards such as GB1499.1 - 2024 and GB1499.2 - 2024 had regulations on the diameter range, weight tolerance, and mixed batch requirements of hot-rolled plain steel bars and hot-rolled rib steel bars. The requirements were constantly updated and stricter.
concrete screwThe cement screw was a type of screw conveyor, commonly used to transport cement. Each section was connected by a flange-shaped connection, and there was a sealing pad at the connection. In the concrete mixing plant, the cement screw of the LSY series cement conveyor can be used to transport cement and fly ash materials. It is also suitable for chemical, smelting, granary processing, storage and other places. In terms of price, for example, Qufu City had spiral screw feeder, U-shaped spiral feeder, custom cement screw feeder, and other related products. The price was 350 yuan. There might be some problems in the process of use, such as the connection bolt being easy to break. In the special case of the cement warehouse bursting, it might be related to the condition of the cement warehouse. For example, some construction site owners thought that the screw conveyor's conveying capacity was too large when the cement warehouse burst. In addition, when making the coiling dragon, you can use Solidworks to draw the coiling dragon by creating sketches, stretching, inserting helices, converting solid references, lofting and bending.

The concrete behavior of loveThere were many aspects to love. In terms of attention and listening, they would listen attentively to every word the other party said and deeply understand the content of the other party's expression. In terms of time, he would not hesitate to sacrifice his personal leisure time. Able to accept the other party's shortcomings and show an tolerant attitude.
If you truly loved someone, you would be willing to give up scarce resources for the other party. This kind of sacrifice was often irrational and did not ask for anything in return. For example, rich people were willing to spend time and be loyal, ordinary people were willing to spend money, and grumpy people were willing to spend patience. They would want the other party to live a better life and have the willingness to take care of the other party. They were more mature in their thinking and had a sense of responsibility. They would have each other in their future plans. They would do things based on their relationship. Even if the novelty passed, they still had the habit and impulse to be good to each other.
At any time and place, be willing to introduce others generously to relatives and friends, giving them a sense of security and existence, so that they can show their true self without any scruples and get a response. They would truly appreciate the other party's brilliance and only show the weak parts of their hearts to the other party. There was no limit to the other party's growth. He would also be willing to pay for the other party and be very attentive to the other party's matters.
In addition, loving a person could also be expressed as paying attention to each other's every move and caring about everything about the other person; working hard to keep pace with the other person; restraining one's bad temper; giving the other person a certain guarantee in terms of money; wanting to make each other's lives closer to each other and bring the other person into one's circle of friends; becoming worried about gains and losses, not talkative, at a loss; seeing the other person's own beauty filter, having a tendency to stick to others, etc.
