Stabilization Of Expansive Clays In Road Subgrade With MH Type Cement And With Other Stabilizing Agents: Type I Clinker Dust, Clinker Dust, OPC And Quicklime

Abstract

The lack of adequate stabilization of expansive clays where different structures are built is a threat to foundations, as it can cause settlement during dry periods and expansion during wet periods. To address this issue, a comparative analysis of the Fabián Palacios Citadel in the Andrés de Vera Parish of the Portoviejo Canton was carried out. The objective is to mitigate clay expansion by stabilizing the road subgrade using Type MH Cement and other stabilizing agents. The analysis involved several mixtures containing MH Cement and additional stabilizing agents. The results of the study emphasize the potential of using a mixture of 5% MH Cement and 1% quicklime to improve soil characteristics. This particular mixture proves to be very effective in reducing the liquid limit and free expansiveness of the soil. Additionally, it improves soil resistance, as demonstrated by the California Bearing Index (CBR). These findings indicate that this combination offers a viable solution to stabilize and improve soil quality in various construction and civil engineering projects.
