El gran incremento de construcciones en la ciudad de Lima entre ellas el distrito de Jesús María ha generado gran cantidad de residuos produciendo grandes daños ambientales sobre todo por demoliciones de edificaciones menores por falta de un manejo adecuado, aunque existe el Reglamento para la Gestión y Manejo de los Residuos Sólidos de las actividades de la construcción y demolición. El presente estudio titulado: El reciclaje de residuos por demolición de edificaciones menores en el Desarrollo Sostenible, caso Distrito Jesús María tuvo como objetivo analizar y evaluar la aplicación del reglamento referido a la gestión y manejo de residuos por demolición de edificaciones menores para realizar una propuesta de acciones para el cumplimiento y de aprovechamiento de estos residuos como su reciclaje. La investigación es de tipo cuantitativo de diseño descriptivo correlacional. ...

This study aimed to analyze the impact of photoluminescent pigments on the mechanical properties of concrete, specifically its resistance to compression and bending. The type of research was descriptive with a review of previous experimental works that evaluate concrete with pigments in concentrations of 0%, 1%, 2%, and 4%. The results showed a significant decrease in compressive and flexural strength with increasing pigment concentration, the reduction being up to 31.4% and 16.7%, respectively. Despite these decreases, there will be an improvement in visibility in the dark and an increase in the luminous intensity of the pigmented concrete. However, an increase in water absorption and lower resistance to freeze-thaw cycles was also found, affecting the durability of the material. The study concludes that photoluminescent pigments have a negative impact on the compressive and flexural st...

Photoluminescence is revolutionizing construction, especially in concrete pavements and structures, by offering both aesthetic and functional improvements. Photoluminescent pigments, which store and emit light, can positively influence the physical-mechanical properties of concrete. This study examines pigments such as strontium aluminate, zinc silicate, zinc phosphate and calcium fluorescence, evaluating their emission life and their impact on the compressive strength and durability of concrete. Photoluminescent pigments absorb light energy and release it in the form of visible light, providing prolonged luminescence. Strontium aluminate stands out for its high intensity and durability, significantly improving the compressive strength of concrete. Zinc phosphate also offers long emission and is highly resistant to moisture. Zinc silicate improves wear resistance, while calcium fluoresce...

La investigación está enfocada en el estudio del comportamiento sismorresistente de dos sistemas estructurales: el sistema metálico de rejilla rígida perimetral y sistemas convencionales existentes en nuestro entorno, específicamente en terrenos ubicados en zonas sísmicas “4” tales como Lima Metropolitana. La delimitación territorial es al mayor riesgo sísmico al que se someten las edificaciones en comparación a otras regiones donde no se han registrado movimientos telúricos de gran importancia. De este modo, al simular las edificaciones en los peores escenarios de impacto estructural, se obtendrán resultados mucho más eficientes y realistas en lo que respecta a su comportamiento estructural en la realidad. Las estructuras con el sistema metálico de rejilla rígida se analizaron de acuerdo con el número de pisos y al ángulo de inclinación de cada rejilla, asimismo, en...

The objective of the research is to develop a state of knowledge about the use of bioengineering in engineering projects at the national level and in the Latin American region. The influence of the main techniques used is evaluated, evaluating those that include the contribution of the roots of the vegetative material in the Mohr - Coulomb model and the use of the erosion rod and RUSLE methods to estimate the water erosion of a natural slope (slope) unstable. The research is documentary - explanatory with a comparative approach since the value of the safety factor with and without vegetation and the value of current erosion are contrasted using GIS models and the direct method of erosion nails. It is concluded that the use of vegetation, simply or collectively, to improve and protect unstable soils, influences the value of the safety factor, substantially increasing, and minimizing the a...
