EVALUATION OF THE GEOTECHNICAL BEHAVIOR OF A SOIL STABILIZED WITH RED CERAMIC RESIDUE

Abstract

Solid waste, such as red ceramic, has been reused by civil construction with the main objective of reducing their disposal areas and, therefore, the environmental impacts caused. In this way, the present work presents a study of the use of ceramic residues in mixtures with soil for the use in the field of paving and earth works, seeking to improve the geotechnical and mechanical properties of the soil under study. To fulfill the objective, three proportions (10%, 20% and 30%) of red ceramic residues (RCV) were studied in a characteristic soil of Porto Velho/Rondônia (RO). For geotechnical and mechanical evaluation of the mixtures, compaction and unconfined compressive strength (NCCR) tests were used. The results showed a reduction in the maximum dry bulk density and an increase in the optimal compaction moisture. In addition, in the RCNC tests, it was possible to observe an increase in the resistance of the three soils with RCV, thus showing the feasibility of using the ceramic residue as a soil stabilizer.
