随着新技术水平的上升,现代化建设项目的生产工艺逐渐向大型化、联动化、自动化发展,工程结构向高层、群体和轻质、高强结构(件) 发展,从而对工程材料、工程质量、施工工艺提出了更高要求。在(钢筋) 混凝土工程中,混凝土性能趋向轻质、高强、多功能方向发展的情况下,目前仍继续沿用现行的传统施工工艺,将难以满足工程质量和施工速度的要求。一、混凝土工艺改革势在必行我国(钢筋) 混凝土生产工艺一直处于手工操作或小型分散的半机械化作业水平,调制的混凝土强度等级低,强度不稳定,水泥耗用量大,投入多,产出少,已不能适应现代化建设项目的工程结构安全和建筑使用功能的技术标准,这是当前工程施工中的主要薄弱环节,
With the increase in the level of new technologies, the production processes of modern construction projects are gradually becoming larger, more collaborative, and more automated. The project structure is developing toward higher levels, groups, and lightweight, high-strength structures (pieces), and thus the engineering materials, project quality, The construction process puts forward higher requirements. In the case of (reinforced) concrete works, where concrete performance tends to be lightweight, high-strength, and multi-functional, it is still continuing to use the current traditional construction techniques, and it will be difficult to meet the requirements of project quality and construction speed. First, the reform of concrete technology is imperative China’s (reinforced) concrete production process has been in the manual operation or small-scale decentralized semi-mechanized operation level, the modulated concrete strength level is low, the strength is unstable, the cement consumption is large, the investment is more, the production Out of less, it can no longer meet the technical standards for the safety of the engineering structure and the function of the building used in modern construction projects. This is the main weakness in the current construction of the project.
