Design of experimental microconcretes made with crushed sand Produced in the central region of Guerrero.

Abstract

In order to determine the behavior of the crushed
sands of the central region of the state of Guerrero
in the field of the construction industry, basic tests
of quality control were carried out to the aggregates
where it was verified that the material complied
with the specifications of the rules. For the dosage,
the absolute volume method was applied to
determine the mix designs at a simple compressive
strength of 200 kg / cm2 where the crushed sand of
the region was used, as well as the design of mortars
at the same compressive strength Simple where the
crushed sand contained particles no larger than 9.5
mm by calling this microcnocreto mixture. Samples
were made which were tested in simple
compression in 7, 14 and 28 days to obtain the
resistance graphs and to make a comparison
between these two mixtures of Mortar and
microconcrete.
