English title:	USE OF MINING TAILINGS SLUDGE AS A PERCENTAGE SUBSTITUTE FOR CEMENT IN THE DESIGN OF CONCRETE MIXTURE FOR THE PILOT CONSTRUCTION OF FOOTPRINT PLATE IN THE MUNICIPALITY OF VETAS, SANTANDER.
Spanish title:	USO DEL LODO DE RELAVE MINERO COMO SUSTITUTO PORCENTUAL DEL CEMENTO EN EL DISE�O DE MEZCLA DE CONCRETO PARA LA CONSTRUCCI�N PILOTO DE PLACA HUELLA EN EL MUNICIPIO DE VETAS, SANTANDER.
English abstract:	. Mining tailings make up the sterile part of the rock that is discarded after a process of extraction and concentration (beneficiation) of a mineral in order to obtain elements of economic interest. At the end of this process, large amounts of tailings are generated, which can become environmental liabilities if they are not treated properly. In order to minimize their environmental impact and give them a use, a physical chemical study is undertaken as well as a design of mixtures for the percentual replacement of cement by the sludge of the mining tailings produced by the mining company La ELSY LTDA of the municipality of Vetas of the department of Santander. The sludge is used as a substitute of the cementing agent used to produce type D concrete for the construction of footprints and works of art such as pavements, gutters, sewers, separators, pavers, etc, without directly affecting the strength and original properties of the clinker, such as: densities, normal consistency and setting time. This project addresses responds to the need to continue with the production of green gold given that, in spite of having eliminated the use of heavy metals such as mercury and cyanide for the benefit of the gold as of seven years ago, , La Elsy manifests the problem of the environmental liabilities generated by the accumulation of tailings as well as the need for technical studies that validate the use of this inert material in the construction of civil infrastructure, giving it a use that would boost the region and increase its inhabitants� quality of life. This research connects with the design of regeneration programs, which must integrate sustainability criteria and environmental best practices, aimed at minimizing potential negative impacts on the ecosystem structure and function of the moors as well as their derived ecosystem services. Likewise, this proposal harmonizes the fundamental rights to work and to a healthy environment, highlighting that they are not mutually exclusive, and that the conservation of the moor and the protection of the water resources are both compatible with the development of a mining activity focused on continuous improvement, the progressive implementation of environmental and social best practices and the strengthening of a governance for the conservation of the territory.
Spanish abstract:	Los relaves mineros conforman la parte est�ril de la roca que es desechada despu�s de un proceso de extracci�n y concentraci�n (beneficio) de un mineral con el fin de obtener elementos de inter�s econ�mico. Al final del proceso se generan grandes cantidades de relaves que al no ser tratados adecuadamente pueden convertirse en pasivos ambientales. Con el objeto de minimizar el impacto ambiental y darle un uso a los mismos, se realiza un estudio f�sico qu�mico y un dise�o de mezclas para la sustituci�n porcentual de cemento por los lodos del relave minero producido por la empresa minera La ELSY LTDA del municipio de Vetas del departamento de Santander. Los lodos son utilizados como sustituci�n del agente cementante con la finalidad de producir concreto tipo D para la construcci�n de placa huella y obras de arte como andenes, cunetas, alcantarillas, separadores, adoquines etc, sin afectar directamente la resistencia y propiedades originales del clinker, tales como: densidades, consistencia normal y tiempo de fraguado. Este proyecto responde a la necesidad de continuar con la producci�n de oro verde, pues a pesar de implementar desde hace siete a�os la eliminaci�n del uso de metales pesados como el mercurio y el cianuro para el beneficio del oro, La Elsy manifiesta la problem�tica de los pasivos ambientales que genera la acumulaci�n de los relaves mineros y la necesidad de realizar estudios t�cnicos que validen el uso de este material inerte en la construcci�n de infraestructura civil, d�ndole un uso que potencialice la regi�n y aumente la calidad de vida de los habitantes. Esta investigaci�n se conecta con el dise�o de los programas de reconversi�n, que deben integrar criterios de sostenibilidad y buenas pr�cticas ambientales, orientados a minimizar la generaci�n de impactos negativos en la estructura y funci�n ecosist�mica de los p�ramos y los servicios ecosist�micos derivados de estos. Igualmente, la propuesta armoniza los derechos fundamentales al trabajo y a un ambiente sano, resaltando que no son derechos excluyentes y que tanto la conservaci�n del P�ramo como la protecci�n del recurso h�drico son compatibles con el desarrollo de una actividad minera enfocada en el mejoramiento continuo, la implementaci�n progresiva de mejores pr�cticas ambientales y sociales y el fortalecimiento de una gobernanza para la conservaci�n del territorio
