加强混凝土的质量检测与控制成为当今土木工程技术中的重要课题。混凝土是由水泥、砂子、石子三种材料,用水拌合经过凝固硬化后制成的人工石材,近年来,为改善混凝土的施工性能及力学性能往往掺入各种如减水剂、早强剂等外加剂,本文就如何用无破损方法来测定混凝土强度进行了探讨。 Strengthening the quality of concrete testing and control has become an important issue in today’s civil engineering. Concrete is made of cement, sand, stone three kinds of materials, mixing water after solidification hardening made of artificial stone, in recent years, in order to improve the construction performance and mechanical properties of concrete are often mixed with various water-reducing agent, early strength agent And other admixtures, this paper discusses how to determine the strength of concrete without damage.
