摘要
高强混凝土强度等级高,密实性能好,一般运用于高层建筑、大跨度桥梁等结构中,如果混凝土的配合比设计不合理,会影响到混凝土的强度,缩短混凝土构件的使用寿命。文章论述了高强度混凝土在原材料选择及配合比设计时应注意的一些要点。
High-strength concrete featured by high strength and fine density is commonly used in high-rise building and bridges with large span, but inappropriate mix proportioning of it will not only reduce strength of concrete and finally shorten service life of concrete structure. This paper discusses essentials in raw material selection and mix proportioning of high-strength concrete.
