For many years now, unlike metal and wood, concrete and reinforced concrete are often considered permanent materials. In reality that is not the case. The structures are often defective. They cause rapid wear and tear of the structure, reducing exploitation time.
Experts point out four stages that need to be noted to protect the sustainability of construction projects as follows: Design ensures high expertise and construction ensures high quality, timely preventive repairs, Fix local damage, conduct major repairs or replace structures.
Protecting reinforced concrete structures against corrosion is very necessary, such as preventing corrosion caused by chlorine. If the thickness of the protective layer is increased from 1.5 to 2 cm, the durability time will double. The cost of increasing the thickness of the protective layer will be much smaller than the cost of very difficult repair work for structures with damaged substrates as a result of reinforcement corrosion.

The volume of production of reinforced concrete and wall bricks from different types of concrete has increased sharply. Production of pre-stressed reinforced concrete for flat roofs without water-proof bitumen also increased more than before. Under these conditions, the concrete is subjected to prolonged compression and must resist the formation of cracks, which over time often leads to water penetration.

The preference for building on a large scale more and more identical reinforced concrete houses with a boring, monotonous appearance has not been popular with consumers. Investing in the construction of large factories specializing in the production of uniform housing complexes that do not change does not meet the aspirations of consumers, nor does it promote the development of new design and technology. The above situation can be overcome by slightly changing the components through combining assembled components with monolithic construction. In addition, it is also possible to organize the production in the factory of difficult-to-construct structures such as columns, stairs, and balconies combined with the use of sliding formwork at the core of high-rise buildings.
