Resumen

In this research, the relationship between "added cement" and "compressive strength of rammed earth walls" was explored using a linear regression model. These walls were constructed using aggregates from Colpa Alta, Huánuco, Peru, and analyzed using bivariate data analysis. The motivation for this study stemmed from the heightened challenges faced by the local populace in constructing confined masonry houses due to increased building material costs triggered by the COVID-19 pandemic. Given these circumstances, rammed earth walls present a more economical alternative to conventional construction, although their structural capacity requires enhancement. For the study, 60 aggregate samples were gathered on-site in compliance with the Peruvian Technical Standard E-080 and categorized into four groups of 15, with cement replacements at 5%, 10%, and 15%. Compressive strength assessments were conducted on these samples, and statistical methods were employed to analyze the results. The outcomes indicated a notable enhancement in compressive strength in the cement-augmented samples compared to traditional rammed earth blocks, establishing a robust correlation between "added cement" and the "compressive strength of rammed earth walls." This correlation and its impact were quantitatively delineated through the developed linear regression model.
