Abstract Not surprisingly, with the increased awareness of environmental issues, construction with raw (crude, unbaked) earth (subsoil) is gaining renewed interest. However, it suffers from a poor image and from the difficulty to meet modern productivity standards and to pass some durability tests designed for industrial materials. The recent trend is to overcome these drawbacks by “stabilizing” the material most often with Portland cement (PC). Here we show that stabilization with PC is in general neither technically nor environmentally advisable. It brings only moderate mechanical improvement at a high environmental cost. Rather than massively transforming crude earth into a low quality concrete, it would be more appropriate to adapt the architectural practice and/or to look for milder ways to improve properties. In this respect, the recent successful attempts to improve the workability and the strength of raw earth by controlling the dispersion of its fine fraction seem to be particularly promising.

土混凝土。重新审视稳定

摘要 毫不奇怪，随着环境问题意识的提高，使用未加工的（粗制的、未烘烤的）泥土（底土）进行建筑的人们重新获得了兴趣。然而，它的形象很差，难以满足现代生产力标准，也难以通过一些为工业材料设计的耐久性测试。最近的趋势是通过最常用的波特兰水泥 (PC)“稳定”材料来克服这些缺点。在这里，我们表明使用 PC 进行稳定化通常在技术和环境上都不是可取的。它以高昂的环境成本只带来适度的机械改进。与其将粗土大量转化为低质量的混凝土，不如适应建筑实践和/或寻找更温和的方法来改善性能。在这方面，
