Aprovechamiento de material aluvión en la fabricación de mobiliario urbano

Abstract

The investigation is born from the question: ¿what is the reuse that is given to the solid waste generated during the process of sweeping the roads of the city of Bogotá? For decades the waste (alluvium) has been swept, collected and disposed of in a sanitary landfill without giving it any use or reincorporating it into the economic production chain. For the construction sector, this material has particular characteristics to be used in different construction processes. The alluvium is a sandy material, which is found on the sides of the roads, it is generated by the effect of winds, water runoff, and vehicular drag. Currently there is no use for this material. Thanks to the fact that the laboratory results were satisfactory and that the prototypes made with alluvial concrete presented good performance, the incorporation of alluvial concrete in urban furniture manufacturing processes (bollards, roof racks, tablets, poles, among others) is proposed. The alluvium would be used replacing 100% of the river sand in the dosages, since its non-structural behavior is optimal, taking into account that the material has physical qualities very close to river sand. In this way, the material is used in the construction sector and the consumption of river sand in concrete mixes for non-structural elements would be minimized.
