Reuse of laboratory waste as aggregate in the manufacture of structural concrete

Abstract

Civil construction presents itself as an efficient alternative to absorb the waste generated in the laboratories linked to the theme, through its use as an aggregate in obtaining recyclable concrete, the opportunity to use it in making new products is envisaged, in addition to from the economic and environmental contribution, expansion of the number of jobs, environmental preservation, among others, starting to play an important role with regard to the economy and social practices. Through the use of this material, different traces in the composition of the concrete were designed, in order to verify its characteristics regarding absorption and resistance to compression, developed by laboratory tests that allowed to obtain results, which after being tabulated and analyzed, makes - it is possible to find a way to minimize environmental impacts, through its reuse as raw material in the manufacture of by-products, aiming at its application in the buildings themselves or in their surroundings. The approached methodology is given by action research through experimentation through laboratory analysis. With the use of these residues, the objective is to reduce the cost of manufacturing concrete parts, providing a sustainable destination for the materials now discarded. The values obtained show favorable results for the use of laboratory residues from civil construction in the manufacture of structural concrete, both in buildings and in pavements.
