construction engineering and materials

the rapid development of social economy has promoted the development of construction industry in our country. at present, the urban construction work in our country is in full swing. therefore, the quality of the construction project has been widely concerned by people from all walks of life. the quality control of construction engineering is very important for the development of urban economy. construction engineering construction must use the corresponding building materials, the quality of building materials is directly related to the quality of the entire construction project, so the quality detection of building engineering materials is particularly important.


construction materials have far-reaching significance for the quality of the entire construction project, and strengthening the quality inspection of construction materials is crucial to the quality of the entire construction project, which provides a strong guarantee for the smooth development of construction. with the continuous improvement of the level of scientific information technology in china, the detection methods of construction engineering materials are becoming more and more scientific and standardized. therefore, it is of great help to strengthen the quality detection of construction engineering materials, and the quality of construction engineering materials is guaranteed correspondingly. however, due to the low comprehensive quality of a few testing staff, the quality testing equipment of construction engineering materials is not sound enough, so the quality testing work of construction engineering materials can not be carried out efficiently and at a high level. there are some problems in the quality inspection of construction engineering materials, which need to be found in time and solved with effective countermeasures to promote and improve the quality of construction engineering materials.
