从理论和实际应用两个角度,对加气混凝土砌块全生命周期碳排放量加以分析,对比了加气混凝土砌块与烧结页岩空心砖的碳排放量。从理论分析角度上看,加气混凝土砌块因轻质多孔能够显著降低碳排放;从实际应用角度来看,加气混凝土砌块在平衡饱水后无论与其干燥状态或页岩空心砖相比,碳排放量均显著增加,不再具有减少碳排放的效果。因此,应加强加气混凝土砌块配套材料的研发和应用,以保证使用过程中良好的保温隔热效果,减少使用中的碳排放量。
From the perspectives of theory and practical application, the life cycle carbon emissions of aerated concrete blocks are analyzed, and the carbon emissions of aerated concrete blocks and sintered shale hollow bricks are compared. From a theoretical analysis point of view, aerated concrete blocks can reduce carbon emissions significantly due to their lightweight and porous structure. From the practical application point of view, aerated concrete blocks, compared with their dry state or shale hollow brick, Carbon emissions have increased significantly, no longer have the effect of reducing carbon emissions. Therefore, research and development and application of aerated concrete block supporting materials should be strengthened to ensure good thermal insulation effect during use and reduce carbon emissions in use.
