Evaluation of Concrete Resistance as a Functiono Water Dosage Variation
Keywords:
Concrete, Water, Ideal Dose
Abstract
Different amounts of water in concrete and the consequences of dosages were analyzed. Aggregate granulometry assays, slump tests and specimen disrupture assays were conducted for the analysis of resistance (according to mold aging and water quantity) coupled to data sampling reports. Data analysis and the result of slump test and compression resistance showed that a decrease in the water-cement (w:c) ratio produced a higher resistance concrete, although with very low reduction and difficult handling. If the water quantity is increased, resistance test results decrease but workability increases. Results show that the conventional factor for a 15 MPa fcck and w:c ratio = 0.755 is the ideal water quantity.
