Caracterización de ladrillo de concreto con cal hidratada y plástico PET reciclado

Abstract

At present, when it comes to building, materials of technical and economic quality are sought, with low energy consumption for the environment, and in response, eco-friendly bricks, masonry units that include recycled materials in their matrix, have emerged. The objective was to characterize the solid concrete brick with the addition of hydrated lime and recycled PET plastic in the district of Chota. The mix for compressive strength (f'c)= 175 kg/cm2 for 1 m3 of concrete consisted of 7.76 bls cement, 0.35 m3 sand, 0.30 m3 clay and 0.22 m3 water; which were modified with lime in 3, 6 and 9% of the weight of cement and with recycled PET in 3, 6 and 9% of the volume of aggregates. It was determined that all the designs decrease relatively the compressive strength, but present higher compressive strength than the initial design, therefore, they comply with the technical characteristics for the elaboration of concrete. In technical, economic and environmental terms, the best concrete dosage was with 9% lime and 9% PET, which have higher compressive strength in units (188.75 kg/cm2), higher compressive strength in piles (180.32 kg/cm2) and higher shear strength in walls (58.79 kg/cm2) than the standard concrete brick specified in the E.070 standard.
