Agregados de la cantera jubones y su influencia en la resistencia del hormigon, empleado en la construcción de obras civiles

At present, the construction area has undergone a growth and development that requires urban projects that denote the population growth that has arisen in the city of Machala, the same one that requires of optimal materials that guarantee the structures of the houses. Due to this, the present work titled "AGGREGATES OF THE JUNCTS QUARTER AND ITS INFLUENCE IN THE RESISTANCE OF THE CONCRETE, EMPLOYEE IN THE CONSTRUCTION OF CIVIL WORKS", focuses on the necessity of carrying out the study of the aggregates extracted from the quarry of the Jubones And the influence they have on the concrete resistance, which is used in the construction of civil works, which generates the labor development in the city of Machala. The construction sector is one of the most benefited in this development process due to the increased demand of those who need a living space, which generates the use of this type of aggregates conformed by resistant material and qualified for the building process household. Therefore, it is proposed to analyze the quality of the aggregates of the quarry of the Jubones to be used as materials in the casting of concrete, with technical guarantees of professionals in the branch of civil engineering specialized in the analysis and dosage of the aggregates to be used In the process of building. Since, to a large extent, the personnel involved in these processes shows a low knowledge regarding the degree of quality that is obtained when using this type of resources in this class of buildings. The purpose of this work is to carry out different studies related to the quality of the material based on the volume of the coarse aggregate of the concrete, the density of the cement used, the exact calculation of the unit mass of the loose gravel, Of gravel mass, calculation of loose aggregate mass of sand, specific density of the fine aggregates by weight and proportion, specific density of coarse aggregates by weight and proportion, sand grain analysis, crushed gravel density by weight and proportion and To finalize the volume of coarse aggregate per unit volume of the concrete. The research methodology for the study of this project is based mainly on the quantitative and qualitative methods because it is based on the direct observation of the quality of aggregates of the quarry of the Jubones and their exact measurement to verify the performance of the concrete, considering that the Aggregates and the use of good concrete during a foundry are the fundamental basis during the process of construction of civil works; However, it guarantees professional work and above all a high percentage of housing durability and safety, as well as the quality of the material used. Likewise, the importance of the present study in which the environment corresponding to the construction of civil works is evaluated to improve the offered services and to demonstrate with facts the quality of the material used and the provenance of the aggregates.
