Low-slump high-strength concrete suitable for centrifugal construction forming as well as preparation method and application of low-slump high-strength concrete
The invention discloses low-slump high-strength concrete suitable for centrifugal construction forming and a preparation method and application of the low-slump high-strength concrete. The low-slump high-strength concrete comprises the following raw materials in parts by weight: 550-650 parts of cement; 70 to 90 parts of I-grade fly ash; 70 to 90 parts of S105 mineral powder; 70 to 90 parts of silica fume; 550 to 650 parts of quartz sand; 310-380 parts of basalt aggregate of which the particle size is greater than or equal to 5mm and less than 16mm; 720-790 parts of basalt aggregate with the particle size larger than or equal to 16 mm and smaller than or equal to 31.5 mm; 90 to 130 parts of mixing water; according to the low-slump high-strength concrete, the slurry aggregate layering phenomenon cannot occur in the centrifugal forming process, compared with traditional concrete, a concrete prefabricated part has the advantages of being high in strength, high in crack resistance, good in durability and the like, and telegraph poles with excellent performance can be prepared through the centrifugal forming process.
本发明公开了一种适用于离心施工成型的低坍落度高强混凝土及其制备方法和应用,包括以下重量份的原料:水泥:550‑650份;I级粉煤灰:70‑90份;S105矿粉:70‑90份;硅灰:70‑90份;石英砂:550‑650份;5mm≤粒径<16mm的玄武岩骨料:310‑380份;16mm≤粒径≤31.5mm的玄武岩骨料:720‑790份;拌合水:90‑130份;减水剂:9‑13份,所述低坍落度高强混凝土在离心成型工艺中不会出现浆体骨料分层现象,混凝土预制构件相比于传统混凝土具有强度高、抗裂能力强、耐久性良好等优势,可通过离心成型工艺制备出性能优异的电线杆。
