Análise da viabilidade técnico-econômica do tijolo modular de solo-cimento sem finalidade estrutural para o município de Jataí, Goiás

Abstract

The soil-cement brick, also known as the ecological brick, emerges as a sustainable and cost-effective alternative to ceramic blocks, standing out for its less environmentally impactful production process and lower consumption of natural resources. This study aimed to evaluate the technical and economic feasibility of soil-cement bricks through a literature review and laboratory tests conducted in accordance with ABNT NBR 8491 – 2013 and ABNT NBR 8492 – 2013 standards, focusing on the material's dimensional properties, compressive strength, and water absorption. Additionally, a detailed budget was prepared to compare the construction costs using soil-cement bricks and ceramic blocks, considering regional prices, local supplier data, and labor costs. The results indicated that the soil-cement brick met all the requirements of the standard, except for the compressive strength test, which was compromised due to infrastructure limitations. Compared to ceramic blocks, the soil-cement brick demonstrated excellent cost-benefit performance, both financially and in terms of environmental and energy efficiency. The research also highlighted the superior quality of soil- cement bricks supplied in the Jataí region, reinforcing their technical and economic feasibility and establishing the material as a sustainable alternative for local civil construction. The study contributes to the increased acceptance of soil-cement bricks in civil construction in the municipality, demonstrating their potential to reduce environmental impacts and costs in construction projects.
