TENA, A.; LIGA, A.; PEREZ, A.  y  GONZALEZ, F.. Proposal for improved mixes to produce concrete masonry units with commonly used aggregates available in the Valley of Mexico. Rev. ALCONPAT [online]. 2017, vol.7, n.1, 00005. ISSN 2007-6835.  https://doi.org/10.21041/ra.v7i1.170.

In this paper, a proposal is done to update the masonry index compressive strength design value f* m for solid concrete masonry units for the masonry guidelines of Mexico´s Federal District Code (NTCM-2004). Solid units were made by taking into account the characteristics of the most commonly used raw materials available in the Valley of Mexico to fabricate such units in the Metropolitan Area of Mexico City. Different tests were conducted for both raw materials and the obtained concrete units. Based upon test results, it is illustrated why it is much better to design masonry structures based upon the experimental data of the units to be used at the construction site rather than using index values proposed in building codes.

Palabras llave : masonry; concrete masonry units; compressive strength.
