高性能混凝土试验与施工质量控制

高性能混凝土具有高耐久性、高工作性和高体积稳定性等优点。高性能混凝土的广泛应用能够提高建筑工程质量,降低全寿命周期综合成本,推动节能减排,发展循环经济,促进建筑业技术进步,是国家十三五大力推行的绿色建筑材料。高性能混凝土需要采用低水胶比,选用优质原材料,掺加足够数量的矿物掺合料和高效外加剂。优化施工流程,控制施工质量,是保证高性能混凝土结构综合性能和延长结构寿命的关键。

Test and Quality Control of High Performance Concrete Construction

The high performance concrete has advantages of high durability, high performance and high volume stability. Application of high performance concrete can improve the construction quality, reduce the life cycle cost, promote energy-saving emission reduction, development the circular economy,and promote the construction industry and technological progress.It is a green building material thirteenth to the implementation of the national policy. High performance concrete is compounded with low water cement ratio, high quality raw materials, a sufficient number of mineral admixtures and high efficient additives. Optimize the construction process and control the construction quality are the key to ensure the comprehensive performance of high performance concrete structure and prolong life.
