This study investigates the correlation between the compressive strength of soil-cement blocks and the cement content in their mixture. A systematic literature review was conducted, collecting data from 12 scientific articles, resulting in 87 studies. The selected studies provided important information on the cement content, compressive strength, and casting characteristics of the blocks. The data were organized and statistically analyzed using Microsoft Excel 2019. A linear regression model was applied to evaluate the relationship between cement content and compressive strength measured at 28 days of curing. The results indicate a positive correlation (Pearson's correlation coefficient, r = 0.589) as described in the literature, suggesting that increasing cement content generally improves compressive strength. However, the results also reveal that other factors, such as soil type, compaction pressure, curing conditions, and moisture content, significantly influence the improvement in block performance. This research contributes to the optimization of soil-cement formulations, promoting more sustainable construction practices, minimizing cement consumption, and ensuring structural integrity. Limitations of the study include the variability in experimental conditions between the reviewed studies and the reliance on secondary data. Future research should incorporate experimental investigations to validate and expand on these results.

Despite its advantages, conventional soil-cement has limitations in terms of mechanical strength and durability, especially in environments with high humidity or high structural demands. The development of high-performance soil-cement (HPSC) presents significantly superior mechanical properties. The decentralized production of these panels has resulted in a cost reduction of more than 40%, making them an affordable alternative for low-income communities. Even so, providing technical support for the popularization of HPSC is crucial for the advancement of civil construction and to enable the expansion of affordable and sustainable housing for vulnerable communities. This study focuses on the development of a high-performance soil-cement panel, including its manufacturing process and the materials used. The panel was produced using Yellow Argisol soil, found locally in abundant quantities, modified with sand. Measurements of flexural strength and water absorption were carried out, together with a comparison of the strength of high-performance concrete (HPC) found in the literature. The developed panels present an average flexural strength of 6.71 MPa. Additionally, water absorption reached 5.99%, indicating the high performance of this material, which is comparable to high-performance concrete but more economical and sustainable. This contribution confirms the viability of transferring HPSC technology and highlights its social impact on civil construction.

Este estudo teve como objetivo principal analisar a correlação entre o teor de cimento e a resistência à compressão de corpos de prova de solo-cimento, com base em uma revisão sistemática da literatura. Foram analisados 26 artigos científicos, totalizando 227 dosagens avaliadas. As fontes selecionadas apresentavam informações quantitativas sobre teor de cimento, resistência à compressão e características de moldagem. Os dados foram organizados e analisados estatisticamente no software Microsoft Excel 2019, aplicando-se um modelo de regressão linear para avaliar a relação entre o teor de cimento e a resistência à compressão aos 28 dias de cura. Os resultados indicaram uma correlação positiva, porém de baixa magnitude (r = 0,31), sugerindo que o aumento do teor de cimento tende a elevar a resistência mecânica. Observou-se também que variáveis como tipo de solo, umidade, compactação e cura exercem influência significativa no desempenho do material. O estudo contribui para o aprimoramento de formulações de solo-cimento mais sustentáveis, com menor consumo de cimento e bom desempenho estrutural. As principais limitações relacionam-se à variabilidade das metodologias experimentais e à utilização de dados secundários. Recomenda-se a realização de pesquisas experimentais futuras para validar e expandir os resultados obtidos.
