Effects of Incorporating Date Palm Waste as a Thermal Insulating Material on the Physical Properties and Mechanical Behavior of Compressed Earth Block

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

本文介绍了一项试验研究 以检查压缩土块(CEB)的机械、热和物理性能 并对其进行微观结构分析. 压缩土块(CEB)采用椰枣废料骨料(DPWA)作为隔热材料 并用生石灰稳定. 研究结果表明 集成椰枣废料集料(DPWA) 的砌块的隔热性能有了相当大的改善. 还发现 当DPWA含量增加时 CEB的抗压强度和抗弯强度值下降 但仍保持在压缩土块(CEB)所主张的间隔内. 此外 CEB弹性模量与弯曲强度和抗压强度遵循相同的模式. 扫描电子显微镜 (SEM) 观察和EDX结果证实了与CEB机械和热性能相关的所有结果
