Abstract

This study evaluates the influence of sawdust ash, glass powder and rice husk ash as admixtures for partially replacing fine aggregate in concrete for rigid pavement applications. Compressive strength tests were conducted at 5%, 10%, 15%, and 20% replacement levels. Rice husk ash achieved the highest compressive strength of 10.40 N/mm2 at 10% replacement after 28 days, closest to the control. However, sawdust ash and glass powder exhibited reduced strengths as replacement levels increased. The maximum compressive strength obtained did not meet the required target for rigid pavement applications.
