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.
