Conferencia de la 20th LACCEI International Multi-Conference for Engineering, Education, and Technology: “Education, Research and Leadership in Post-pandemic Engineering: Resilient, Inclusive and Sustainable Actions”. hybrid event, Boca Raton, Florida- USA, junio 18 - 22.

La presente investigación se basó en determinar el efecto de la adición del aditivo SikaCem como plastificante y superplastificante en la resistencia del concreto permeable utilizando el método ACI 522R para el diseño de la mezcla. En cuanto al diseño de tipo experimental, se tuvo como muestra 189 probetas de concreto permeable, considerando los ensayos previos de los materiales respectivos siguiendo las normas NTP, de igual manera para el concreto en estado fresco y endurecido. Por otro lado, para el diseño de mezcla, se consideró las dosificaciones de 0%, 0.25%, 0.50% y 0.75% de plastificante; asimismo, 1.00%, 1.25% y 1.50% de superplastificante y paralelamente probetas sin aditivo de concreto permeable para una resistencia de f’c = 210 kg/cm2 . En base a las conclusiones, las dosis de aditivo plastificante y superplastificante hubo un incremento proporcional a edad inicial, ...

We describe the results of the study of aerosol optical depth (AOD) and Direct Radiative Forcing (DRF) at the top of the atmosphere (TOA), obtained in the period 2004 using the MODIS sensor of the TERRA satellite for Peru. Where it is observed that the AOD value can take maximum values around 0.5, resulting in aerosol DRF in the upper part of the atmosphere. The results indicate that the FRD is between [-5 0] W / m2.

In this work, the spatial dynamic behavior of the aerosol index for the department of Junín is exposed. The basic information for the development of this research is satellite data obtained from NASA. The AURA satellite that has the OMI sensor installed has been monitoring the aerosol index (AI) since October 2004-2018. The satellite observations are as a whole a historical series of the concentration of the index, the data also have geographic coordinate information, which is why it was used to evaluate and simulate the spatial behavior using Kriging's spatial interpolation methodology. Where the greatest amount of suspended particles is observed both in the dry and wet season in the urban area that belongs to the province of Huancayo.

La rápida urbanización de las ciudades está cambiando el clima local, lo que genera altas temperaturas y entornos urbanos densos y difíciles, carentes de agua y vegetación[1]. La presente contribución estima la intensidad de Isla de Calor Urbano Superficial (ICUS) durante el periodo 2001 – 2022 para el Área Metropolitana de Huancayo (AMH), Perú. Se cuantificó formación de la Isla de Calor Urbano Superficial, a partir de 2 métodos: el primero es el método de Streutker, el cual ajusta la temperatura superficial del suelo (LST) (superficie urbana y rural) a una superficie Gaussiana. El segundo, método de cuantil propuesto por José Flores, usa la diferencia entre el cuantil 0.95 de LST del área urbana y la mediana del LST del área rural. Ambos métodos usan data de sensoramiento remoto de LST a 0.05⁰ de resolución, obtenido del sensor MODIS a bordo del satélite TERRA y ...

21st LACCEI International Multi-Conference for Engineering, Education, and Technology: “Leadership in Education and Innovation in Engineering in the Framework of Global Transformations: Integration and Alliances for Integral Development”, Hybrid Event

This work presents results of Aerosol Optical Depth (AOD) and Direct Radiative Force (DRF) at the top of the atmosphere (TOA), obtained during monitoring campaigns carried out at the Huancayo Observatory of the Geophysical Institute of Peru (OH-IGP ) in April and August 2022. In these campaigns, a Sun CIMEL photometer was used to measure the microphysical and optical properties of aerosols at wavelengths ranging from 340 to 1020 nm, and a low-cost Purple-air sensor to quantify the concentration of material particulate (PM), in fine and coarse modes. The AOD results indicated values in the range 0.06-0.22. The daily averages of PM2.5 and PM10 did not exceed Peru’s current Environmental Quality Standards (50 μg/m³ and 100 μg/m³). The air quality index (AQI) calculated for PM2.5 and PM10 was classified as good. On some days during the campaigns, the air quality was classified as moder...
