Diseño de hormigones con material reciclado

Abstract

The technical project in question is based on the design of concrete with recycled material as a replacement for the daily coarse aggregate, for the part of the laboratory tests the INEN Regulation was used for both the recycled material and the fine aggregate, as well as for the in the matter of dosage, the ACI 211.1 standard was applied. Using the tables presented by the ACI 211.1 Standard, it was decided to use a W/C ratio of 0.6, which will project a resistance of 210 kgf/cm2 at the end of the 28 days of curing for each recycled material used in the concrete design, such as they are concrete, brick and block rubble respectively. For the recycled material, it was decided to use concrete, brick and block rubble from the demolitions of civil works in the city of Pasaje, for the fine aggregate, sand from the Jubones River was used, for the crushing of the recycled material, crushing was applied with combos always looking for an optimal size that can be applied correctly to the tests. In the case of the slump in ACI Standard 211.1, a slump of 15 cm to 17.5 cm was chosen with a quantity of water of 202 with a percentage of air of 1.5, taking as a reference that the maximum nominal size of the recycled material is 1 in. Finally, the cylinders of recycled material were tested for compression stress tests, obtaining results in units of kN which the conversion must be carried out.
