Nano-modified ultrahigh-strength steel fiber concrete and preparation method thereof
The invention discloses nano-modified ultrahigh-strength steel fiber concrete and a preparation method thereof, and relates to the technical field of building concrete. The concrete disclosed by the invention is prepared from the following components in parts by weight: 370 to 420 parts of Portland cement, 80 to 120 parts of mineral powder, 30 to 50 parts of fly ash microbeads, 30 to 60 parts of silica fume, 12 to 20 parts of a high-performance water reducing agent, 40 to 160 parts of steel fibers, 0.05 to 0.25 part of graphene oxide, 3 to 20 parts of nano silicon dioxide, 600 to 800 parts of sand, 900 to 1100 parts of stones and 110 to 130 parts of tap water. The nano-modified ultrahigh-strength steel fiber concrete provided by the invention contains the substances such as the steel fiber, the graphene oxide and the nano silicon dioxide, so that the interface microstructure of set cement and aggregate can be improved, and the mechanical property, the impermeability and the durability of the concrete can be remarkably improved.
本发明公开了一种纳米改性超高强钢纤维混凝土及其制备方法，涉及建筑混凝土技术领域。按重量份计，本发明的混凝土包含有以下组分：硅酸盐水泥370‑420份、矿粉80‑120份、粉煤灰微珠30‑50份、硅灰30‑60份、高性能减水剂12‑20份、钢纤维40‑160份、氧化石墨烯0.05‑0.25份、纳米二氧化硅3‑20份、砂子600‑800份、石子900‑1100份和自来水110‑130份。本发明提供的纳米改性超高强钢纤维混凝土，成分中含有钢纤维、氧化石墨烯、纳米二氧化硅等物质，可改善水泥石与骨料的界面微结构，可显著提高混凝土的力学性能、抗渗性以及耐久性。
