abstract = "An experimental character research was carried out. A conventional concrete
mixture was made with the mechanical resistance to compression of 17.5 Mpa.
The materials used in the concrete mixture were analyzed and selected based on
the parameters established in the Colombian Technical Standards and the ASTM
International Standards. They were made 6 test cylinders with the mentioned
concrete mixture to which, the compressive strength of the concrete was checked
it, 3 of them 7 days after they were made and the rest of them 28 days later,
respectively. Thereafter, their drying process by immersion, the data thrown by
the tests were averaged and tabulated. The Hospital waste solid incinerated and
treated by Ecosteryl machine which is located at Guayabal environmental
technology park in Cucuta city was collected. The material resulting from the
incineration and treatment of the hospital solid waste was selected taking only the
particles equal to or less than 20mm resulting from the crushing process by
Ecosteryl. With the selected Particulate material, 3 experimental mix designs were
made, which 2.5, 5 and 7.5% of the total weight of the natural stone aggregates present in the conventional concrete mixture was replaced. With each
experimental mixture made, 6 cylinders were tested at 7 and 28 days, a process
carried out in the same way as that implemented in the conventional concrete mix
for both tests and data collection and analysis. The comparative tables showed
that the experimental mixture I, where 2.5% of the total weight of the aggregate of
the conventional concrete mixture was replaced, was the one that obtained the
highest compressive strength surpassing the result of the conventional concrete
mixture.",
