Abstract
- XXXVI Simposium Nacional de la Unión Científica Internacional de Radio, URSI 2021, Vigo, Spain (online), 20-25 Sep. 2021.-- Research conducted in the framework of MIRACLE Project (Photonic Metaconcrete with Infrared RAdiative Cooling capacity for Large Energy savings, GA 964450), coordinated by Dr. Jorge Sánchez Dolado, from Centro de Física de Materiales (CFM).<br />In this work, a study of the viability of using concrete for radiative cooling is done by theoretically analysing some of the main compounds of concrete: C3S, CH and CSH. Atomistic simulations have been employed for determining the structure and the dielectric response of these phases. Interestingly, the materials have theoretically shown a night-time net cooling power of 55.68 W, 60.96 W and 62.43 W respectively. This preliminary study shows the potential of concrete as a possible cheap, scalable and widely used night-time radiative cooling structural material. Further research must be done in order to achieve a higher reflection in the solar band for day-time radiative cooling. To calculate de emissivity of the compounds, an analytical model has been used, which has nearly zero error and computes the data much faster than a simulator.<br />Este trabajo ha recibido financiación del programa de investigación e innovación Horizonte 2020 de la Unión Europea, proyecto MIRACLE, Grant Agreement 964450.
