Partially Replacement of Cement by Rice Husk Ash and Saw Dust Ash in Concrete

Abstract

This abstract summarizes research on the use of rice husk ash (RHA) and sawdust ash (SDA) as partial cement replacements in concrete manufacturing as a means of conserving resources. The building sector is looking for greener options to lessen its carbon footprint as the environmental effects of conventional cement manufacturing become more apparent. Agriculture and wood industry byproducts RHA and SDA are being considered as potential additives to concrete that would improve its qualities while reducing its environmental effect.
In this study, we test how replacing a portion of the cement with RHA and SDA affects the mechanical, durability, and sustainability properties of the resulting concrete. To evaluate the efficacy of various concrete combinations, we run a battery of tests in the lab that measures their compressive strength, tensile strength, and durability Split tensile strength. Life cycle evaluations also examine the positive effects on the environment, such as lower carbon emissions and less waste.
The results of this research shed light on the use of RHA and SDA as sustainable additives in concrete manufacturing, providing a greener and more cost-effective option for the building sector. This study adds to the continuing efforts to create greener building techniques that are in line with global sustainability objectives by minimizing the use of typical cement and recycling agricultural and industrial leftovers. Here, we show that it is possible to use RHA and SDA in concrete, opening the door to a greener manner of building infrastructure.
