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

His study aimed to assess the strength of 30 concrete specimens produced with Portland cement, incorporating various concentrations of detergent. The experiment comprised six reference specimens using standard Portland cement and anadditional six specimens with the inclusion of plasticizer additives. The consistent trait was maintained across all six studied concentrations. The reference Portland cement specimens were prepared without the addition of any additives. Specimens labeledas dosages 01 to 05 received synthetic detergent in varying amounts, while the final dosage incorporated a plasticizer additive. Slump tests were conducted on all specimens to evaluate the concrete's workability. The molding and curing procedures followedthe standards outlined in NRB NM 67(1997) and NBR 5738 (2013) for concrete, respectively. These procedures were executed using equipment from the civil construction laboratory at Unesc-Polo Colatina. Following the molding process, the specimens were submerged in water tanks until they underwent a 28-day curing period. Subsequently, they were subjected to a breaking test utilizing an automated press of the EMIC brand, model: PC200c. Analysis of the resistance results revealed that dosages 1 to 5 exhibited lower strengths, ranging from 10.79 MPa to 5, in comparison to the reference concrete dosage with a strength of 21.44 MPa. Notably, the plasticity of these dosages (1 to 5) was found to be directly proportional to the amount of detergent applied to the concrete.
