As one of the most commonly used building materials in engineering project construction, the quality of cement directly determines the quality of the whole construction project and the safety of users. The construction unit shall select the appropriate test and detection method according to the actual situation and strictly control the material quality. This paper focuses on the analysis of the test and detection of cement materials and expounds the specific methods for reference.展开更多

In the past, the control methods caused great pollution to the natural environment, and extensive control also caused various problems in the quality of construction projects. In recent years, many new technologies and methods have been applied to the architectural design industry in China, especially the application of BIM technology in the design of prefabricated buildings, which has attracted the general attention of technical experts and staff. It can not only improve the efficiency of architectural design, but also ensure the quality of architectural engineering. This paper explores the design and application of prefabricated buildings, hoping to provide reference for practitioners.展开更多

Commercial blocks are gradually favored by urban residents, and a large number of commercial blocks are built in cities, among which the commercial blocks with the theme of "antique" are the most representative. The application of antique architectural design in commercial street, which carries modern urban life and embodies the charm of traditional culture, is of positive significance for excavating urban culture and enhancing its connotation and value.展开更多
