Green high-performance concrete prepared from waste pavement concrete and preparation method of green high-performance concrete
The invention provides green high-performance concrete prepared from waste pavement concrete and a preparation method of the green high-performance concrete. The green high-performance concrete is prepared from the following raw materials: 260 to 360 parts of cement, 310 to 430 parts of waste pavement concrete, 86 to 119 parts of fly ash, 280 to 320 parts of fine aggregate, 540 to 680 parts of coarse aggregate, 10.8 to 12.2 parts of a water reducing agent, 3.4 to 5.2 parts of a fiber material, 6.9 to 8.2 parts of a foamed aluminum material and 143 to 198 parts of water. The method comprises the following steps: crushing, screening and calcining waste pavement concrete to obtain concrete powder; the environment-friendly concrete prepared from the waste pavement concrete has the advantages of good heat insulation property, strong sound attenuation performance, high compressive strength, high durability and strong carbonization resistance.
本发明提供了一种利用废弃路面混凝土制备的绿色高性能混凝土及其制备方法，原料：水泥260‑360份、废弃路面混凝土310‑430份、粉煤灰86‑119份、细骨料280‑320份、粗骨料540‑680份、减水剂10.8‑12.2份、纤维材料3.4‑5.2份、泡沫铝材料6.9‑8.2份、水143‑198份；将已废弃的路面混凝土经过破碎、筛分、煅烧后成混凝土粉末。本发明利用废弃路面混凝土制成环保混凝土，具有隔热性好、消音性能强、抗压强度高、耐久性高、抗碳化强的优点。
