Carbonized regenerated micro-powder heat-insulating foam concrete and preparation method thereof
The invention relates to carbonized regenerated micro-powder heat-insulation foam concrete and a preparation method thereof, the carbonized regenerated micro-powder heat-insulation foam concrete comprises a foaming agent and a mixture, the foaming agent accounts for 1.5 wt%-2.0 wt% of the mixture, and the mixture accounts for 0.5 wt%-1.5 wt% of the mixture. The mixture is prepared from the following raw materials in percentage by weight: 18 to 22 weight percent of carbonized regenerated micro powder of 0 to 0.075 mm, 28 to 32 weight percent of cement, 8 to 12 weight percent of attapulgite, 0.8 to 1.2 weight percent of water reducing agent and 37 to 41 weight percent of water. The regenerated micro powder subjected to carbonization treatment is used as a mineral admixture to replace cement, the maximum use amount is 40wt.%, and the attapulgite is added to enhance the porosity; the prepared carbonized regenerated micro-powder thermal insulation foam concrete has the strength of 3.62 MPa and the thermal conductivity of 0.28 W/Mk, and is beneficial to enhancing the functional application of a building material system; the raw materials are wide in source and low in price, consumption of natural resources and CO2 environmental harm are greatly reduced, and the carbonized regenerated micro-powder heat-insulation foam concrete is simple in processing flow, low in price and convenient to widely apply.
本发明涉及一种碳化再生微粉隔热泡沫混凝土及其制备方法，其中碳化再生微粉隔热泡沫混凝土包括发泡剂和混合物，发泡剂的重量份占混合物重量份的1.5wt％～2.0wt％，混合物包括如下重量份配比的原料：0～0.075mm碳化再生微粉18wt％～22wt％、水泥28wt％～32wt％、凹凸棒土8wt％～12wt％、减水剂0.8wt％～1.2wt％和水37wt％～41wt％。本发明使用经过碳化处理后的再生微粉作为矿物掺合料替代水泥，最大用量为40wt.％，并加入凹凸棒土增强孔隙率；制备出的碳化再生微粉隔热泡沫混凝土，强度达到了3.62MPa，且导热率进为0.28W/Mk，有利于增强建材体系的功能化应用；原料来源广泛且价格便宜，大大减少了天然资源的消耗和CO2环境危害，碳化再生微粉隔热泡沫混凝土的加工流程简单价格低廉，便于广泛应用。
