Optimizing the physical and mechanical properties of cement stabilized rammed earth construction blocks.

Abstract

This research focuses on the improvement of the physical and mechanical properties of cement- stabilized rammed earth (CSRE) blocks. The approach included characterizing soil samples using sieve analysis to assess soil particle size distribution, moisture content tests, and maximum dry density evaluations to determine the best achievable compaction characteristics. These tested samples were taken from a total of three different soil samples that were prepared with different concentrations of cement (0, 2, 4, 6, and 8 percent) to determine the influence of the cement proportion on the blocks’ strength and durability. The blocks were compacted and cured for a duration of 7,14 and 28 days, then they underwent compressive strength testing using a Universal Testing Machine (UTM) and water absorption measurement for durability. The data was analyzed to find the most beneficial cement-soil ratio that would achieve maximum strength while remaining within economical limits. The results showed the possibility of CSRE blocks being used as a construction material that is cost-effective while being mechanically reliable.
