Igneous rock mineral admixture for railway high-performance concrete
The invention belongs to the field of building materials and specifically relates to an igneous rock mineral admixture for railway high-performance concrete. The admixture is prepared from 80-90% of ground igneous rock powder (A), 0-10% of a siliceous reinforcing material (B), 0-10% of an aluminum-silicon reinforcing material (C), 0-10% of a grinding aid (D) and 0-5% of an excitant (F). The admixture is suitable for preparation of railway high-performance concrete; the problem of preparation of railway high-performance concrete in areas with shortage of traditional admixtures such as fly ash and slag powder is mainly solved; the application range covers a cast-in-place concrete structure and a prestressed concrete structure; and all performance indexes of the prepared concrete meet the technical requirements of railway concrete (TB/T 3275-2018).
本发明属于建筑材料领域，具体涉及一种铁路高性能混凝土用火成岩质矿物掺和料，该掺和料由80~90%的磨细火成岩石粉（A）、0~10%的硅质增强材料（B）、0~10%的铝硅质增强材料（C）、0~10%的助磨剂（D）及0~5%的激发剂（F）组配而成。该掺和料适用于铁路高性能混凝土制备中，主要用于解决粉煤灰、矿渣粉等传统掺和料短缺地区铁路高性能混凝土的制备难题，适用范围涵盖现浇混凝土结构和预应力混凝土结构，配制混凝土的各项性能指标均满足《铁路混凝土》（TB/T 3275‑2018）的技术要求。
