USE OF GRASS FLOOR MANUFACTURED WITH CDW AGGREGATES IN SHOES: an alternative for urban drainage

Abstract

The growth of the civil construction sector is related to two major urban problems: the waterproofing of the soil with the expansion of buildings and the generation of construction and demolition waste (RCD), which represent a significant portion of the solid waste generated in urban centers. Given this, combining the importance of urban drainage with sustainable construction, this study aimed to verify the feasibility of using concrete grass floors, manufactured with the total replacement of natural aggregates by RCD aggregates. For this, the RCD was screened, followed by the production and characterization of the aggregates. Subsequently, the study of different concrete lines was carried out and with the line defined in 1: 3: 5, cylindrical, prismatic specimens and grass floor units were molded, which were subjected to tests of resistance to compression, flexural tensile strength and constant load permeability. The results obtained were satisfactory in terms of mechanical resistance and permeability of the floor-grass units, demonstrating the feasibility of using them for pavements as an alternative for urban drainage.
