Anti-shrinkage anti-segregation concrete and preparation method thereof
The invention discloses anti-shrinkage anti-segregation concrete, which is prepared from the following raw materials in parts by weight: 60 to 100 parts of construction waste, 15 to 35 parts of ordinary Portland cement, 5 to 12 parts of diatomite, 1 to 2 parts of nano calcium carbonate, 1 to 2 parts of calcium oxide expansion clinker, 1 to 2 parts of calcium sulphoaluminate expansion clinker, 1 to 3 parts of nickel slag, 1 to 2 parts of beta-cyclodextrin, 1 to 2 parts of gypsum, 1 to 3 parts of coagulation accelerator, 1 to 2 parts of foam stabilizer. 0.1 to 1 part of a water repellent, 0.1 to 1 part of an additive, and 1 to 2 parts of a foaming agent. The invention discloses a preparation method of the anti-shrinkage anti-segregation concrete, which comprises the following steps: carrying out ball milling on the nickel slag, the calcium oxide expansion clinker and the calcium sulphoaluminate expansion clinker, adding the diatomite and the nano calcium carbonate, homogenizing and sieving to obtain a prefabricated material a; stirring the prefabricated material a and other raw materials, keeping stand, pouring and preliminarily curing the above, and obtaining a pre-cured blank; and demolding the pre-cured blank material, performing autoclaved curing, then performing natural curing, and drying to obtain the anti-shrinkage anti-segregation concrete.
本发明公开了一种防收缩抗离析混凝土，其原料按重量份包括：建筑垃圾60‑100份，普通硅酸盐水泥15‑35份，硅藻土5‑12份，纳米碳酸钙1‑2份，氧化钙膨胀熟料1‑2份，硫铝酸钙膨胀熟料1‑2份，镍渣1‑3份，β‑环糊精1‑2份，石膏1‑2份，促凝剂1‑3份，稳泡剂1‑2份，憎水剂0.1‑1份，外加剂0.1‑1份，发泡剂1‑2份。本发明公开了上述防收缩抗离析混凝土的制备方法，包括：将镍渣、氧化钙膨胀熟料、硫铝酸钙膨胀熟料球磨，加入硅藻土、纳米碳酸钙，均化，过筛得到预制料a；将预制料a和其余原料搅拌，静置，浇筑，初步养护得到预养护坯材；将预养护坯材脱模，蒸压养护，然后自然养护，干燥得到防收缩抗离析混凝土。
