ANALYSIS OF CONCRETE COMPRESSION RESISTANCE DUE TO THE INCORPORATION OF SYNTHETIC DETERGENT AS A PLASTICIZING ADDITIVE

Abstract

The aim of this study was to compare the strengths of 30 specimens cast from Portland cement concrete with different concentrations of detergent. Six reference Portland cement concrete specimens and six Portland cement concrete specimens with plasticizer additives were used. The trace used was the same for the samples of the 6 dosages studied. The Portland cement reference concrete was molded with concrete without the additive mixture, the 01 to 05 dosages of specimens received the addition of different synthetic detergents and, finally, the last dosage was concrete with a plasticizing additive. For all the specimens, the slump test was carried out to analyze the concrete slump of each dosage. Procedure for molding and curing test specimens and NBR NM 67 (1996): Concrete: The molding of the specimens and the slump test were carried out in accordance with NBR 5738(2015): Concrete: The consistency of the cone trunk,respectively, with the help of equipment from the civil construction laboratory at Unesc - Colatina (ES). After molding, the specimens were stored in water tanks until they had cured for 28 days and were then broken using an EMIC model automated press: PC200c. Analyzing the results of the strengths of the test specimens, it can be seen that the strength of dosage 4 obtained an average of 10.79 MPa, compared to the dosage of the reference concrete with an average of 21.44 MPa, but the plasticity of these dosages (1 to 5) was directly proportional to the amount of detergent applied to the concrete.
