Ready-mixed concrete industry "14th Five-Year Plan" started smoothly
Ready-mixed concrete that condenses cement and sand and gravel aggregates is a major material used in national infrastructure and engineering construction. It is an important part of infrastructure materials in major countries. It is used in housing construction, bridges, airports, highways, railways and various industrial mining, It is widely used and indispensable in the construction of national defense projects. At the same time, ready-mixed concrete also plays an important role in important fields such as ecological protection, environmental protection and waste, and emergency rescue.

Analysis of building materials market in 2022 and outlook in 2023
In 2022, China's economy is facing demand contraction, supply shock, expected weakening of the "triple pressure", superimposed on some housing enterprises capital explosion, the new coronary pneumonia epidemic repeatedly and other multiple adverse factors, economic growth slowed down significantly. Although in the moderate advance investment policy to promote the infrastructure to play a strong role in the bottom, but the shortage of funds, consumer confidence in the downturn led to this year's building materials industry-wide profits fell sharply, the overall performance can be summarized as "supply and demand decline, high costs, profit contraction, average price down". In 2023, consumption may be difficult to rebound in the short term, the real estate industry is still in the downward channel, infrastructure is still the main force to bear the steady growth, it is expected that in 2023 the building materials industry "supply and demand continue to contract, the cost is high, the average price volatility narrowed, the bottom of the profit is not high". In this context, the industrial chain of various varieties of building materials may accelerate the integration, optimize the industrial structure, and actively respond to the opportunities and challenges brought by changes in market supply and demand.
