| Sumario: | In this work, the results of the laboratory tests applied to 30 pieces of concrete blocks are presented: 15 with 2 holes and 15 solid ones, manufactured mechanically and made by hand, in 3 manufacturing sites in the city of Tuxtla Gutiérrez, Chiapas. The purpose of the laboratory tests is to determine the geometric characteristics (dimensions) and the resistance to compression of the pieces; likewise, compare the results obtained with current standards. The results show that the average compressive strength does not comply with what is established in the standard; On one hand, the average compressive strength obtained in hollow parts varies between 67.90 kg/cm2 (mechanical manufacture) and 13.44 kg/cm2 (handmade), and is below 90kg/cm2, which corresponds to the value established in the standard; On the other hand, the average resistance obtained in the pieces of solid blocks varies between 68.22 kg/cm 2 (mechanical manufacture) and 12.67 kg/cm2 (handmade), which, compared to the value of 150 kg/cm2 of the standard, it is observed that the results are extremely below the established recommendation. The previous results warn of the need to control the quality of the compressive strength of the concrete blocks, manufactured by the supplier companies, to guarantee that they comply with the standards of masonry structures for homes or other types of buildings, and with this, contribute to reducing the seismic vulnerability of the homes of low- income families in the state of Chiapas, who prefer the use of this material because of its low cost. |
