Incorporación de ceniza de cascarilla de arroz en la fabricación de bloques de hormigón

Abstract

Abstract: This work investigates a construction material based on an agro-industrial waste, specifically rice husks, in the manufacture of lightweight blocks for slabs. The goal is to find an alternative solution that contributes to waste reduction and improves the block's properties. Through the controlled combustion process of the husks, its ash, rich in amorphous silica, is obtained, which acts as a pozzolanic material. Chemical tests were conducted to characterize the ash, and physical and mechanical tests were performed to determine its viability for use in the dosage. Therefore, this research project presents an alternative to improve the use of this agricultural waste by reusing rice husks in a way that collaborates with more economical construction materials. This research focused on improving sustainability in the construction industry by using these agro-industrial wastes with low environmental impact. The research results demonstrate the potential of rice husk ash, consolidating its role as an efficient additive in the manufacture of concrete blocks.
