Abstract: In recent years, my country's social development has accelerated, and the market economy has shown a significant growth trend. Under this general environment, my country's infrastructure construction and construction industry have entered the fast lane of development and have gradually become the structure of my country's economic system. The core subject. As far as the current status of the construction phase of my country's construction projects is concerned, a huge amount of concrete needs to be produced and consumed every year. Therefore, for the current construction industry, concrete is also the most basic building material in construction projects. Compared with the traditional concrete technology, the cast-in-place concrete technology is innovative and upgraded on its basis, which can ensure the quality of the concrete while realizing the configuration on the construction site. As the key technology and material of project construction, it can be said that the construction technology of cast-in-place concrete will directly affect the safety and quality of the overall building. This article researches on-site concrete construction technology, and conducts in-depth analysis on the key points and diffi culties of the technology, and uses the various stages of the technology application as the entry point, and puts forward suggestions for controlling the quality of cast-in-place concrete construction technology to provide relevant personnel with a certain degree The theoretical basis of this will promote the high-quality development of my country's construction industry.
