Quality Testing Technology for Building Materials
As the pace of urban and rural construction in China continues to accelerate, investment in infrastructure construction continues to increase, and the quality of construction projects is increasingly valued by people. The quality of building materials fundamentally determines the quality of construction projects. Therefore, in order to ensure the quality of construction projects, it is necessary to do a good job in building material testing. However, China's construction project quality testing technology started relatively late, borrowing relevant foreign standards from the beginning, China has gone through a difficult period to have its own relevant standards. At present, China's construction industry is in a period of vigorous development, and the continuous development of construction technology will also promote the continuous development of testing technology. The quality inspection technology of building materials is an important basis for us to conduct building materials experiments. Whether the detection technology is scientific and reasonable, and whether the testing process is well controlled, will affect the scientificity and reliability of our test results. Therefore, testing technology is the "soul" of quality testing. Without scientific and reasonable testing technology, testing work will have nowhere to start and testing results will have no basis.
