Análise da qualidade do concreto curado em baixas temperaturas para traço usual em edificações no município de Campo Mourão Paraná

Abstract

With increased surveillance and the standard of performance, quality and service life of the structures have been significant in corporate profits. However, the cost of replacement parts or even a complete structural, endearing comes the cost of the work. So the aim of the study was to analyze the durability of concrete cured at low temperatures, rehearsing its compressive strength, permeability and water absorption, verifying the effectiveness of the improved grain size in concrete without changing the cost, from a usual trait in the municipality of Campo Mourão-Pr. For this way, managers of works have knowledge about the risks of concreting in cold periods, the advantages of making a composition of aggregates and variations between two types of cements. With the test results, there was an improvement in all three aspects tested for concrete whose granulometric arrangement was improved. With this, it can be stated that the low cure temperature adversely affects the durability and differentiation of dimensions of aggregates improves the quality of concrete.
