Mineralized steam-curing-free exhaust flue and preparation process thereof
The invention relates to a mineralized steam-curing-free exhaust flue which comprises the following components in percentage by weight: 60.9-74.3% of steel slag powder, 0.7-2.1% of a steel slag active exciting agent, 10.0-22.0% of 425 slag cement and the balance of water, when the mineralized steam-curing-free exhaust flue is prepared, firstly, water is added, the steel slag powder, the steel slag activity exciting agent and the 425 slag cement are evenly stirred, and then compression molding is conducted through a compression technology; and then mineralizing the compression-molded exhaust flue by adopting high-temperature waste gas containing carbon dioxide. The exhaust flue is low in cost and capable of utilizing a large amount of waste steel slag. The carbon dioxide gas mineralizes the steel slag powder to improve early and later strength and absorb carbon dioxide to obtain a negative carbon building material; the high-strength and early-strength cement mortar has the characteristics of being free of steam curing, high in strength, early in strength and free of shrinkage, the strength of 80 Mpa or above can be obtained after mineralization is conducted for 24 h, and the maximum strength can reach 111.5 Mpa after 28 d.
本发明涉及一种矿化免蒸养排气烟道，包括以下重量百分比的成分：钢渣粉60.9～74.3％，钢渣活性激发剂0.7～2.1％，425矿渣水泥10.0～22.0％，水余量；矿化免蒸养排气烟道制备时，先加水将钢渣粉、钢渣活性激发剂和425矿渣水泥搅拌均匀后，通过压制工艺压制成型；然后采用含有二氧化碳的高温废气对压制成型的排气烟道进行矿化。提供一种低成本、能大量利用废弃钢渣的排气烟道；二氧化碳气体矿化钢渣粉，提高早期、后期强度，并吸收二氧化碳，得到负碳建材；具备免蒸养、高强、早强、无收缩特性，矿化24h即可获得80Mpa以上强度，28d最高能达到111.5Mpa强度。
