NBR 6122/2019: A Theoretical Analysis of Cost Reduction for the Production of Concrete for Continuous Helix Piles Comparing with the 2010 Version Jhonatan Vieira Lopes

Abstract

Concreting services companies, Concrete Batching Plants, are inserted in a competitive market, always needing to revise their costs to offer consistent values ​​to customers. The present study aims to analyze the revisions of NBR 6122 of the years 2010 and 2019 on concrete for continuous propeller pile, showing that with the 2019 revision it is possible to reduce costs in the production of concrete without losing quality. The work is limited to a study of concrete dosage using the ABCP Method according to NBR 6122/2019, comparing with a dosage of the 2010 version. However, the comparative proved to be efficient, as it provided a cost reduction of approximately 6%/m³ of concrete produced for prop pile.
