Carbon sequestration aerated concrete wall material product based on nickel slag and concrete tail slurry and preparation method of carbon sequestration aerated concrete wall material product
The invention discloses a carbon sequestration aerated concrete wall material product based on nickel slag and concrete tail slurry and a preparation method. The carbon sequestration aerated concrete wall material product comprises the nickel slag, the concrete tail slurry, gypsum, cement, lime, aluminum powder paste and a nucleating agent. The preparation method comprises the following steps: uniformly mixing the nickel slag, the concrete tail slurry and the gypsum, adding the cement and the lime, stirring, finally adding the aluminum powder paste and the nucleating agent, stirring to obtain mixed slurry, performing film injection, curing and demolding to obtain a green body, and performing carbonization curing. According to the invention, the nickel slag and the concrete tail slurry are applied to the aerated concrete wall material product, and a carbonization curing process is combined, so that on the basis that the nickel slag and the concrete tail slurry provide part of siliceous raw materials and calcium raw materials, a large amount of low-activity minerals such as silicate and aluminate in the nickel slag and the concrete tail slurry can be fully excited; and under the induction of the nucleating agent, the CO2 is promoted to generate CaCO3 and SiO2 colloids with calcium silicate components in the nickel slag and the concrete tail slurry, so that reaction conditions are provided for the formation of tobermorite.
本发明公开了一种基于镍渣和混凝土尾浆的固碳加气混凝土墙材制品及制备方法，包括镍渣、混凝土尾浆、石膏、水泥、石灰、铝粉膏和晶核剂；制备时先将镍渣、混凝土尾浆与石膏混匀，再加入水泥、石灰搅拌，最后加入铝粉膏、晶核剂搅拌，制得混合料浆，经注膜、养护、脱模后制得坯体，并进行碳化养护。本发明将镍渣及混凝土尾浆应用于加气混凝土墙材制品中，并结合碳化养护的工艺，在镍渣和混凝土尾浆提供部分硅质原料和钙质原料的基础上，能够充分地将镍渣和混凝土尾浆中低活性的大量硅酸盐、铝酸盐等矿物激发，且在晶核剂的诱导下，促进CO2与镍渣、混凝土尾浆中的硅酸钙组分生成CaCO3和SiO2胶体，为托贝莫来石的形成提供了反应条件。
