Resumen
En la actualidad, la gran industria productora de áridos a lo largo del país, no satisface las crecientes demandas de materiales de construcción, al ser empleados tanto en la construcción centralizada como en la ejecución de viviendas por esfuerzo propio. Esta demanda hace que se incrementen los costos de transportación y dificulta la disponibilidad de materiales; de ahí la idea de emplear molinos alternativos en talleres de Ecomateriales situados directamente en los municipios y consejos populares donde se incrementa la producción local de materiales de construcción.
De cualquier modo, la producción local de materiales debe cumplir con los parámetros de calidad exigidos por las normas cubanas lo que garantiza la sostenibilidad de las construcciones, en este sentido en el presente trabajo se realiza un estudio de monitoreo de los áridos producidos localmente, para conocer en relación con las materias primas empleadas y la tecnología disponible el estado de la calidad de los áridos en dos diferentes talleres de la provincia, al verificar si los mismos cumplen con el establecido en la norma cubana 251-2013 Áridos para hormigones hidráulicos. Requisitos.
Al analizar la influencia del árido obtenido de la trituración, en la fabricación de mezclas de hormigón se evaluó los principales parámetros físico-mecánicos del hormigón con los áridos procedentes de la producción local, los ensayos y resultados se obtienen en el laboratorio de la facultad de construcciones donde se elaboraron hormigones con diferentes dosificaciones, alcanzando valores de 14 MPa y 54 MPa estos a los 28 días.
At present, the large industry producing aggregates throughout the country, does not meet the growing demands of building materials, to be used both in the centralized construction and in the execution of homes by their own efforts. This demand causes transportation costs to increase and makes material availability more difficult; hence the idea of using alternative mills in Ecomaterials workshops located directly in the municipalities and popular councils where the local production of construction materials is increased. In any case, the local production of materials must comply with the quality parameters demanded by Cuban standards, which guarantees the sustainability of the constructions, in this sense in the present work a monitoring study of locally produced aggregates is carried out, for now in relation to the raw materials used and the technology available the state of the quality of the aggregates in two different workshops of the province, to verify if they comply with the established in the Cuban standard 251-2013 Aggregates for hydraulic concretes. Requirements When analyzing the influence of the aggregate obtained from the crushing, in the manufacture of concrete mixtures the main physical-mechanical parameters of the concrete were evaluated with the aggregates coming from the local production, the tests and results are obtained in the laboratory of the faculty of constructions where concretes were made with different dosages, reaching values of 14 MPa and 54 MPa these at 28 days.
