Ultra-high performance concrete suitable for being used in vibration environment and application of ultra-high performance concrete
The invention discloses ultra-high performance concrete suitable for being used in a vibration environment and application of the ultra-high performance concrete. The vibration frequency of the vibration environment is 1-10 Hz, and the vertical amplitude of the vibration environment is 3-10 mm. The ultra-high performance concrete comprises the following components in parts by weight: 100 parts of Portland cement, 25-35 parts of fly ash, 15-25 parts of (i) silica fume or (ii) a mixture of silica fume and metakaolin, 120-140 parts of river sand, 20-30 parts of water, 3.5-5 parts of a water reducing agent and 15-35 parts of steel fibers. After the ultra-high performance concrete is coagulated and hardened in a vibration environment, steel fibers can be stably and uniformly distributed in the ultra-high performance concrete, and a test block obtained after coagulation and hardening has relatively low porosity, a relatively excellent pore structure and relatively good mechanical properties, and can meet the actual application requirements in the field of bridge deck pavement.
本发明公开了一种适于振动环境中使用的超高性能混凝土及其应用，振动环境的振动频率为1～10Hz，上下振幅为3～10mm；超高性能混凝土按重量份计，包括如下组分：100份硅酸盐水泥、25～35份粉煤灰、15～25份(i)硅灰或(ii)硅灰与偏高岭土的混合物、120～140份河砂、20～30份水、3.5～5份减水剂和15～35份钢纤维。该超高性能混凝土在振动环境中凝结硬化后能够保持钢纤维稳定均匀地分布在超高性能混凝土中，凝结硬化后得到的试块具有较低的孔隙率、较优的孔结构和较好的力学性能，可满足桥面铺装领域的实际应用需求。
