Abstract

The aim of this research is to select a material with low environmental impact, easily obtainable in rural areas, and cost-effective, to improve the mechanical properties of adobe. Because of this, it is necessary to determine the compressive strength of stabilized adobe by incorporating coal ash and eucalyptus wood sawdust in different percentages. The research was experimental and carried out at the Universidad Privada del Norte, 60 units of adobe blocks were made on the Cinva Ram machine classified into 5 types, conventional adobes, adobe plus 2% and 3% coal ash and adobes plus 3% and 5% wood sawdust. Subsequently, they were tested at the age of 28 days on the compressive strength machine where the following data were obtained, for conventional adobe 38.57 kg/cm2, adobe plus 2% and 3% coal ash with values of 55.45 kg/cm2 and 25.93 kg/cm2 respectively, and for adobe plus 3% and 5% of wood sawdust, 25.76 kg/cm2 and 25.90 kg/cm2 were obtained, respectively. It is concluded that the addition of 3% coal ash to conventional adobe increases compressive strength by 43.76% compared to conventional adobe.
