Evaluación de la resistencia a la tracción indirecta del adoquín hexagonal -incorporando tiras de alambre- mediante la norma NTE-INEN 3040

Abstract

This research project is carried out with paving stones manufactured in the city of Quito with the objective of evaluating and improving the mechanical properties of conventional hexagonal paving stones, to provide a solution to the problems of manufacturers, contractors and contractors who use paving stones in their various civil works, since they must comply with the quality standards established in the NTE-INEN 3040 CONCRETE PAVERS standard. REQUIREMENTS AND TEST METHODS – 2016. Because the traditional sample is made with simple concrete, the main objective is to develop a hexagonal paver incorporating strips of wire (annealed) of 20cm in length and 2.5mm in diameter in its internal cross section and that complies with the mechanical performance in accordance with the aforementioned technical standard. In addition, several samples are made without wire and then incorporating it progressively, from 1 unit to 4 placed as reinforcement in a transverse direction in 2 different arrangements, the first in the form of a hook and the second as a staple, in such a way it will be possible to obtain different results
