Determinação de traços de concreto com utilização de materiais usuais de Barra do Garças-MT

Abstract

Materials with high strength along with durability are increasingly being required in the construction industry, that leads concrete to becoming a global preference in the preparation of structural elements. The following project had the purpose of elaborating a method for creating concrete mixtures that were compatible with the resources of a town as small as Barra do Garças – MT. Several concrete specimen were made utilizing local materials, then were tested to verify if said specimen met criteria established by standard concrete norms. The results reinforced the importance of knowing the characteristics and properties of aggregates being utilized to produce concrete in construction sites, since there is a noticeable variation in physical properties in each aggregate, it is highly important to produce a concrete with satisfactory resistance and workability. The tests in this project are capable of determining these parameters.
