Resumen
The present study aimed to analyze the
stabilization of clay soils for the optimization of urban
subgrades through the use of common glass in the province
of Tarma, Peru. An experimental design methodology was
employed, with 5 test pits excavated for soil extraction.
Recycled glass was used, ground, and added in varying
percentages of 0%, 10%, 20%, 30%, and 60%. An
observation sheet was used to record all relevant data. The
results indicated that the SiO2 content in the glass was
71.166% and the CaO content was 25.683%, with Si
(53.355%) and Ca (41.355%) being the predominant
elements. Regarding Maximum Dry Density (MDD), the
highest value was recorded with the addition of 20% ground
glass (1.987 g/cm³). Additionally, the Optimum Moisture
Content (OMC) decreased as the percentage of added glass
increased. Concerning the California Bearing Ratio (CBR) at
100% of the MDD, the maximum value was observed with
20% glass addition (17.8%), indicating that the subgrade is
of good quality. Finally, the ANOVA analysis showed an F-
statistic value of 267.1722 and a p-value of 0.00, suggesting
statistically significant differences between the groups with
different percentages of glass addition. It was concluded that
the addition of ground glass improves the density, moisture
content, and load-bearing capacity of the soil, providing an
effective solution for the stabilization of clay soils in terms
of sustainability and performance.
