Use of Ceramic Waste in Different Percentages as a Replacement of the Fine Aggregate in Mortars

With the growth of the population and, consequently, of civil construction, there was an increase in the consumption of natural resources, generating a large amount of solid waste and contributing to various environmental impacts. The application of solid waste in civil construction aims to reduce environmental pollution and the construction of sanitary landfills. Thus, this work presents the use of ceramic waste as a substitute for fine aggregate in proportions of 10, 20, and 30% in mortars. To evaluate its use, tests of consistency index, density in the fresh state, tensile strength in flexion and axial compression, tensile bond strength, and microstructural analysis were performed using the Scanning Electron Microscopy (SEM) test. Through the results, it is concluded that the best proportion used is 10% of ceramic waste, which indicated results superior to the reference mix, presenting smaller pores, resulting in high strengths. At 28 days, it obtained 2.91 MPa of tensile strength and 9.40 MPa of compressive strength.
