| The study aims to assess the impact of variable binder content and the direction of compaction on the properties of the hemp-magnesium composites. These two factors may influence the scope of application of the developed composites (e.g. as a lightweight insulating filling of a frame wall, or a heavier material for load-bearing applications or in prefabrication). Capillary rise, thermal conductivity, compressive and flexural strength in two directions, as well as the absorbability were tested. An analysis of the environmental impact of the composites was also prepared. When a magnesium binder is used, it is possible to produce lightweight composites with low thermal conductivity (0.07 W/(m∙K)), but also heavier ones with high compressive (1.73 MPa) and flexural (0.98 MPa) strength. It is possible to improve selected parameters after changing the direction of compaction. The thermal conductivity of composites compacted in a direction parallel to the heat flow was lower by 17–25% compared to a perpendicular direction. The positive effects of changing the direction of compaction can be used in prefabrication by adjusting the compaction process. The impact on climate change varies significantly due to the proportion of these materials from 55.07 kg CO2 eq. to 358.64 kg CO2 eq. | |
| 本研究旨在评估不同粘合剂含量和压实方向对大麻镁复合材料性能的影响. 这两个因素可能会影响所开发复合材料的应用范围（例如，作为框架墙的轻质隔热填充物，或用于承重应用或预制的较重材料）. 测试了毛细管上升、导热系数、两个方向的抗压和抗弯强度以及吸收性. 还对复合材料的环境影响进行了分析. 当使用镁粘合剂时，可以生产出导热系数低（0.07 W/（m∙K））的轻质复合材料，但也可以生产出具有高抗压强度（1.73 MPa）和抗弯强度（0.98 MPa）的较重复合材料. 可以在改变压实方向后改进所选参数. 与垂直方向相比，沿平行于热流的方向压实的复合材料的导热系数降低了17-25%. 改变压实方向的积极影响可以通过调整压实工艺用于预制. 由于这些材料的比例从55.07千克二氧化碳当量到358.64千克二氧化碳当量，对气候变化的影响差异很大. |
