Ferronickel slag aggregate concrete
The intention discloses ferronickel slag aggregate concrete. The concrete is prepared by mixing the following raw material components in parts by mass: 100-150 parts of cement, 100-200 parts of lithium slag powder, 1500-1800 parts of a ferronickel slag aggregate, 100-300 parts of ferronickel slag powder, 5-20 parts of a water reducing agent, 30-50 parts of polymer emulsion and 120-150 parts of mixing water. According to the method, the ferronickel slag aggregate is pretreated, so that the crushing value of the ferronickel slag aggregate is increased, and the risk of potential alkali aggregatereaction of the ferronickel slag aggregate concrete is reduced. Meanwhile, the use amount of cement is small, the alkalinity of the lithium slag powder and the nickel-iron slag powder is low, the overall alkalinity of the concrete is reduced through the combination of the lithium slag powder, the nickel-iron slag powder and the cement, and the risk of alkali-aggregate reaction is reduced.
本发明公开了一种镍铁渣骨料混凝土，所述混凝土由以下质量份原料混合制备组成：水泥100~150份、锂渣粉100~200份、镍铁渣骨料1500~1800份、镍铁渣粉料100~300份、减水剂5~20份、聚合物乳液30~50份、拌合用水120~150份。本发明通过对镍铁渣骨料的预处理，提高了镍铁渣骨料压碎值高，降低了镍铁渣骨料混凝土潜在的碱骨料反应的风险。同时本发明中水泥用量少、而锂渣粉与镍铁渣粉的碱度又较低，三者组合降低了混凝土的整体碱度，也降低了碱骨料反应的风险。
