Carbonization curing method of geopolymer cementing material
The invention provides a carbonization curing method of a geopolymer cementing material, and relates to the technical field of building materials. The carbonization curing method of the geopolymer cementing material provided by the invention comprises the following steps: mixing solid waste, an alkali activator and water, and carrying out curing molding to obtain the geopolymer cementing material, sequentially carrying out carbonization curing and standard curing on the geopolymer cementing material; the carbonization curing conditions are as follows: the temperature is 25 +/-2 DEG C, the relative humidity is 95 +/-5%, and the CO2 concentration is 10-20%. By adopting the carbonization curing method provided by the invention, the geopolymer cementing material can be prevented from generating large shrinkage in the curing process, and the volume stability of the sample is ensured; in addition, the use of cement is reduced, so that the carbon emission caused in the cement production process is reduced; and carbon dioxide in the atmosphere can be cured for a long time, so that carbon emission in the whole life cycle of the building material is reduced.
本发明提供了一种地聚物胶凝材料的碳化养护方法，涉及建筑材料技术领域。本发明提供的地聚物胶凝材料的碳化养护方法，包括以下步骤：将固体废弃物、碱激发剂和水混合，进行固化成型，得到地聚物胶凝材料；将所述地聚物胶凝材料依次进行碳化养护和标准养护；所述碳化养护的条件包括：温度为25±2℃，相对湿度为95±5％，CO2浓度为10～20％。采用本发明提供的碳化养护方法，能够避免地聚物胶凝材料在养护过程中产生较大收缩，确保了试样的体积稳定性；此外，本发明减少了水泥的使用，从而降低生产水泥过程中造成的碳排放；还能够对大气中的二氧化碳进行长期固化，从而实现建筑材料全寿命周期碳排放降低。
