项目摘要
New developments in concrete technology have resulted in changes in the types of concrete used in civil engineering applications as well as the performance requirements. Use of new cements and new mineral and chemical admixtures have led to the development of high performance concrete (HPC) and self-consolidating concrete (SCC). HPC and SCC present numerous advantages such as high strength, high elastic modulus, less bleeding, less creep, and high durability. For example SCC is a highly flowable concrete that can spread easily and self consolidate under its own weight without segregation. Stricter performance requirements, mainly durability, have also been imposed on these concrete to ensure longevity. At present, standard test methods have not been developed to ensure quality of the fresh concrete and its compliance with the durability and other structural requirements.
混凝土技术的新发展导致了土木工程应用中使用的混凝土类型以及性能要求的变化。 新型水泥、新型矿物掺合料和化学掺合料的使用导致了高性能混凝土和自密实混凝土的发展。 高性能混凝土和自密实混凝土具有强度高、弹性模量高、泌水少、蠕变小、耐久性高等优点。 例如,SCC是一种高度流动性的混凝土,可以很容易地分散,并在其自身重量下自固结而不分离。 更高的性能要求,主要是耐久性,也被强加在这些混凝土上,以确保寿命。 目前,尚未制定标准测试方法来确保新拌混凝土的质量及其符合耐久性和其他结构要求。
