Lightweight ultra-high performance concrete for bridge engineering and preparation method of lightweight ultra-high performance concrete
The invention discloses lightweight ultra-high performance concrete for bridge engineering and a preparation method thereof, and the lightweight ultra-high performance concrete is prepared from the following material components in parts by weight: 800 to 1200 parts of cement, 100 to 300 parts of silica fume, 100 to 200 parts of fly ash microbeads, 500 to 850 parts of high-strength hollow spheres, 40 to 80 parts of rubber powder, 20 to 40 parts of fiber, 30 to 40 parts of water reducing agent and 0.2 to 0.5 part of defoaming agent. 5 to 10 parts of an expanding agent; and 170 to 200 parts of water. By introducing the light high-strength hollow sphere aggregate, the high-tensile toughening material and the high-performance admixture, the problems of high viscosity, large volume weight, low strength, poor durability, poor volume stability and the like of the traditional light ultra-high performance concrete are solved; therefore, the novel light ultra-high performance concrete based on bridge engineering integrates the properties of light weight, high strength, shock absorption, bending resistance, durability and the like.
本发明公开了一种用于桥梁工程的轻质超高性能混凝土及其制备方法,轻质超高性能混凝土按重量份数计,包括以下材料组分:水泥800‑1200份、硅灰100‑300份,粉煤灰微珠100‑200份,高强空心球500‑850份,橡胶粉40‑80份,纤维20‑40份,减水剂30‑40份,消泡剂0.2‑0.5份,膨胀剂5‑10份以及170‑200份水。本发明通过引入轻质高强的空心球集料、高抗拉的增韧材料及高性能外加剂解决传统轻质超高性能混凝土粘度高、容重大、强度低、耐久性能不良、体积稳定性差等问题,使得基于桥梁工程的新型轻质超高性能混凝土具有轻质、高强、减震、抗弯、耐久等性能于一体。
