Comparación del comportamiento a flexión entre vigas de hormigón simple y vigas de hormigón con adición de virutas metálicas

Abstract

The present experimental work promotes the use of steel wastes generated in metallurgy workshops or lathe shops so that once selected with the proper technique, the metal chips are added into the concrete mix so that it can resist more than what is expected under bending loads. By means of the laboratory tests of the materials such as granulometry, real density, absorption capacity, apparent density, moisture content of the fine and coarse aggregate together with the real density of the cement, dosages were implemented with resistances of (240 and 280) kilograms per square centimeter, complying with three ages corresponding to 7, 14 and 28 days. The standard specimens are presented and subsequently, percentages of (5, 8 and 10) percent of metallic chips are added to the mix to replace the fine aggregate. With a total of 72 prismatic specimens to be tested, under the respective standards. With the results obtained from the three phases, it was verified that the prismatic specimens with steel addition are the ones that present a higher modulus of rupture than the plain concrete specimens, being the outstanding ones for a resistance of 240 kilograms per square centimeter the 10 percent replacement and for 280 kilograms per square centimeter the 5 percent replacement. Therefore, as an analysis, the chip contributes positively to the flexural behavior of concrete, being considered as an environmentally friendly alternative.
