Alkali-activated blast furnace ferronickel slag sprayed concrete

The invention relates to alkali-activated blast furnace ferronickel slag sprayed concrete which is prepared from the following components in parts by mass: 300-600 parts of blast furnace ferronickel slag powder, 200-400 parts of zeolite powder, 50-100 parts of carbide slag, 30-90 parts of sodium hydroxide, 20-60 parts of sodium silicate, 30-50 parts of thickening time control agent, 10-20 parts ofASA resin emulsion, 600-1100 parts of machine-made sand, 100-300 parts of water granulated slag, 3-6 parts of a thickening agent, 1-20 parts of steel fibers and 170-300 parts of water. The sprayed concrete has the advantages of low cement consumption, high toughness and favorable durability, uses abundant industrial wastes, and is beneficial to environmental protection. 本发明涉及一种碱激发高炉镍铁渣喷射混凝土，其由以下质量份的组分组成，300-600份高炉镍铁渣粉，200-400份沸石粉，50-100份电石渣，30-90份氢氧化钠，20-60份硅酸钠，30-50份调凝剂，10-20份ASA树脂乳液，600-1100份机制砂，100-300份水渣，3-6份增稠剂，1-20份钢纤维，170-300份水。本发明喷射混凝土水泥用量少、韧性高、耐久性好，且使用大量工业废弃物，有利于环保。
