| Sumario: | This paper presents the results of a statistical analysis for geometric and mechanical characterization of hollow concrete blocks used in masonry structures in Tuxtla Gutiérrez, mainly for housing. A database of tests carried out on 130 pieces, from 13 different suppliers in the region, was studied. The analysis includes measures of central tendency of geometry, water absorption, shear strength, and correlation between shear stress strength and physical and geometric characteristics of units. Relevant variations in the height and length of the blocks were recorded with respect to what is established in the construction standards usually used as a reference, although their thickness meets the minimum requirements. Minimum values of the shear strength of the tested units are proposed. Correlation study between maximum shear stress and absorption percentage indicates that the higher the porosity of the units, the lower their shear strength. Correlation between maximum shear stress and net area shows that strength to shear stress depends less on this area than on porosity of the units. Finally, correlation analysis against thicknesses of block indicates that these have less influence on strength of units than net area and porosity. |
