Abstract The following research article had as a purpose to analyze the capacity that rubbish have, specifically the brick´s residues as a product of the demolition, for the use of fabricating masonry elements. This, through the design and preparation of a concrete mixture where it was replaced the gross aggregate of natural source in a 70% per mackerel of masonry in baked and triturated brick clay. Then, cylinders of 30 cm x 15 cm and blocks of 30 cm x 15 cm x 15 cm were elaborated for developing mechanical characterization essays, to compare the results, slights variations were observed in these properties. For the development of the research, a complex characterization of the gross aggregated materials (gravel from natural source and triturated brick), the fine aggregated, and the cement was made. That information was fundamental for calculating the design of a mixture for a 21 MPa compression resistance. Consequently, there was necessary to make essays over the fresh concrete for slump and air content. Finally, the fabrication of 30 cm x 15 cm cylinders was necessary too. In this moment, the implementation of three (3) proof mixtures was necessary to determine the proper content of cement, and then, to settle the mixture to obtain the necessary resistance. Finally, masonry blocks were fabricated and with those blocks were possible to characterize the elements mechanically. According to the essays, it was possible to determine that to fabricate masonry mackerel aggregates it is a possible option for concrete mixtures. However, the replacement of the gross aggregate from natural source in a 70% per recycled material, generates a higher consume of cement for obtaining the required resistance. As a conclusion, the triturated brick as a gross aggregated allows a proper management of the concrete mixture, and the masonry elements fabrication produces elements of good density and texture. Also, it is realizable its use in structural and not structural masonry. Keywords: construction and demolition residues, urban solid residues, recycled aggregates, concrete, mechanical essays of the materials. INTRODUCTION The demand of concrete on the construction industry makes really necessary the exploitation of big areas, with the purpose of obtaining aggregates (sand and gravel), which endures a meaningful environmental impact. On the other hand, these quarry zones are remotes, making more expensive the acquisition and transportation of the aggregates. This phenomenon augments the concrete production costs. DANE´s (Departamento Administrativo Nacional de Estadística) statistics present the massive consumption of the pre-mixed concrete in Bogotá, which was of a 33,8% and 36,0% for 2015 and 2016 in national cyphers respectively [1]. This consumption is related to the construction of buildings and dwellings, as is reported by DANE through the IEAC (Indicadores Económicos Alrededor de la Construcción), who say that for the third trimester of the 2016, there was an augment of the 11% in the subsector of the buildings, and an augment of the 1.9% in the subsector of the civil works [2]. This panorama not only allows to affirm that exists a wide consumption of materials, but also, a big production of construction residues –as rubbish are-, whose depository demands big surfaces, which in many cases, are sent to sanitary landfills and slag heaps unsuitably, reducing the useful life of these areas. For instance: Bogotá. The Environment District Secretariat reported that for 2012 year more than 226.000 tons of contaminated rubbish were leave out in Doña Juana´s sanitary landfill, what represented the 10% of the total of residues for that year, restricting the store capacity in a sanitary landfill that presents serious waste harbor problems [3]. These events have generated a massive impact on the environment, like the soil damage in the material exploitation process and the usage of the soil as a mackerel’s store. All these are actions which bring serious modifications in the environment like the removal of trees and the coating plant, fauna displacement, machinery noise, and the pollution of the water, especially when these activities are not regulated.
