    The opacity of concrete limits its potential in applications that require transparency, such as facades and decorative elements. In current building projects, especially in multi-family projects, the need arises for innovative solutions to solve lighting problems, since natural light is limited and is only provided by the free fronts. In Ecuador, the demand for research in this area is urgent due to the energy crisis. The research focused on making an alternative concrete using quartz as a replacement for coarse aggregate in percentages of 10, 20 and 40 percent, to analyze its properties and its influence on compressive strength and light transmittance. Quartz sand was used as a fine material to prevent common sand from dulling the immersed quartz, however, because it did not meet the specified granulometry and fineness modulus, it was mixed with mine sand only at the necessary sieves. The results showed a variation in the absorption capacity of quartz compared to common aggregates, due to its smooth surface, which also hinders adhesion, therefore, the workability of the mixture. Regarding the compression test, it was evident that the resistance decreases as the replacement of quartz as a coarse aggregate increases, although even with this behavior, the concrete continues to meet the design strength. On the other hand, the test carried out on the spectrophotometer indicated that the incorporation of quartz increases the light transmittance.
