Single-grain graded nickel slag sand self-compacting concrete
Single-grain graded nickel slag sand self-compacting concrete is prepared from the following raw materials in parts by weight: 850 to 950 parts of a natural aggregate; 0-308 parts by weight of nickelslag sand; 462 to 770 parts by weight of river sand; 450 to 500 parts by weight of cement; 1-3 parts by weight of a water reducing agent and 190 to 210 parts by weight of water; the particle size of the nickel slag sand is 2.36 mm-4. 75 mm, and the nickel slag sand is single-particle graded nickel slag sand. The stability problem is eliminated through alkali activation, the nickel slag fine aggregate self-compacting concrete is prepared, the problem of environmental pollution is effectively solved, the problem of scarcity of natural river sand in China is solved, and high economic benefits areachieved.
本发明单粒级配镍渣砂自密实混凝土，其原料组成包括，以重量份数计，天然骨料，850‑950重量份；镍渣砂，0‑308重量份；河砂，462‑770重量份；水泥，450‑500重量份；减水剂，1‑3重量份；水，190‑210重量份；其中，且镍渣砂为颗粒尺寸2.36mm‑4.75mm单粒级配镍渣砂。本发明利用碱激发消除安定性问题，制备镍渣细骨料自密实混凝土，不但有效坚决了环境污染问题，还解决了我国天然河砂稀缺的问题，具有较强经济效益。
