粉煤灰混凝土力学特性及耐久性研究
|
Abstract:
粉煤灰是高性能混凝土的主要掺合料之一，掺加粉煤灰直接影响到混凝土的各方面性能，本文利用添加粉煤灰掺合料的混凝土进行力学性能及耐久性能的试验，通过添加“硅酸盐水泥 + 粉煤灰(兼掺减水剂)”制作试块，分析了添加后粉煤灰混凝土的力学特性等，验证粉煤灰会提高混凝土各项性能的猜想，总结出其变化规律，为将来粉煤灰混凝土在实际工程中的应用提供科学依据。
Fly ash is one of the main admixtures of high-performance concrete, which directly affect the various aspects of concrete mixed with fly ash performance. This paper uses concrete with added fly ash admixtures to conduct mechanical and durability tests. By adding “Portland cement + fly ash (also mixed with water reducing agent)” to make test blocks, the mechanical properties of added fly ash concrete, etc. are analyzed, the conjecture that fly ash can improve the properties of concrete is verified, and its change law is summarized, which provides scientific basis for the application of fly ash concrete in practical engineering in the future.
