ABSTRACT

This paper presents an experimental investigation to examine the mechanical, thermal, and physical properties, and to perform the microstructural analysis of compressed earth block (CEB) incorporating date palm waste aggregates (DPWA) as a thermal insulating material and stabilized with quicklime. The findings indicated a quite high improvement in the thermal insulation performance of blocks integrating date palm waste aggregates (DPWAs). It was also found that the compressive and flexural strength values of CEB dropped when the DPWA content increased while still remaining within the interval advocated for compressed earth blocks (CEBs). In addition, the CEB elastic modulus followed the same pattern as the flexural and compressive strengths. The scanning electron microscope (SEM) observations and the EDX findings came to corroborate all the results related to the mechanical and thermal properties of CEBs.

摘要

本文提出了一项实验研究，以检查压缩土块 (CEB) 的机械、热和物理特性，并对将椰枣废骨料 (DPWA) 作为隔热材料并用生石灰稳定化的压缩土块 (CEB) 进行微观结构分析。研究结果表明，结合椰枣废骨料 (DPWA) 的块体的隔热性能有了相当大的改进。还发现，当 DPWA 含量增加时，CEB 的抗压和抗弯强度值下降，同时仍保持在压缩土块 (CEB) 提倡的区间内。此外，CEB 弹性模量遵循与弯曲和压缩强度相同的模式。的扫描电子显微镜（SEM）观察 并且 EDX 的发现证实了与 CEB 的机械和热性能相关的所有结果。
