Single-grain grading nickel slag stone self-compacting concrete
Single-grain grading nickel slag stone self-compacting concrete is prepared from the following raw materials in parts by weight: 534 to 890 parts of natural aggregate; 89 to 356 parts by weight of nickel slag stone; 700 to 800 parts by weight of river sand; 450 to 500 parts by weight of cement; 1-5 parts by weight of a water reducing agent; 150 to 250 parts by weight of water; wherein the nickel slag stone is single-grain graded nickel slag stone with the grain size of 10-20 mm. The invention provides the method for preparing the self-compacting concrete by using the nickel-containing slag stone as the single-grain graded coarse aggregate to replace part of the natural coarse aggregate, so that the environmental pollution caused by nickel slag is reduced, the use of the natural coarse aggregate is reduced, and the cost is effectively reduced.
本发明单粒级配镍渣石自密实混凝土，其原料组成包括，以重量分数计：天然骨料，534‑890重量份；镍渣石，89‑356重量份；河砂，700‑800重量份；水泥，450‑500重量份；减水剂，1‑5重量份；水，150‑250重量份；其中，且镍渣石为颗粒尺寸10mm‑20mm单粒级配镍渣石。本发明提供一种采用含有镍渣石作为单粒级配粗骨料取代部分天然粗骨料制备自密实混凝土的方法，减少镍渣对环境污染，减小天然粗骨料的使用，有效降低成本。
