%X Far-reaching technological progress, manufacturing, and rapidly advancing globalization dictate new conditions for the development and changes in the construction industry. Valorization of by-products and the use of secondary materials in the production of building materials have attracted a lot of attention. Silicate materials were assessed on the basis of their compressive property. An orthogonal compositional plan type 3k (with k = 2), that is, a full two-factor experiment was applied in order to carry out the compressive strength and bulk density tests. Glass sand was added to the silicate mass as a modification. The results show that the compressive strength was higher than that of traditional bricks. Scanning electron microscopy coupled with energy dispersive spectrometry SEM/EDS was used to study the microstructure, whereas the XRD analysis was applied to examine the structures. Laboratory tests were performed on samples with dimensions of 50 ¡Á 50 ¡Á 50 mm. The results show the bulk density increase to the value of 1.75 kg/dm 3, which increases the acoustic performance of the new products. The results of the modifications also indicate changes in the structure of the new bricks. The reference sample contained ¦Á-quartz, zeolite, tobermorite 9A, and calcium aluminum silicate (Ca 2Al 4Si 12O 32), whereas the samples modified with glass sand, the presence of phases such as ¦Á-cristobalite, natrolite, tobermorite 11A, gyrolite, and analcite was recorded.
