Today, concrete strength is one of the most important challenges of the structures against various natural and environmental factors so that it has become a crucial issue in special structures, particularly in earthquake-prone regions. Using higher amounts of cement in concrete provides the strength of the concrete to some extent however experiments have shown that an excessive increase in the amount of cement would reduce the concrete strength. Therefore, the use of additives has become popular. Besides, it is attempted to re-use the materials due to environmental issues. One of the suitable additives among all, which is used as an environment cleaner, is glass. Studies have shown that glass accounts for a major part of the disposed waste materials and, therefore, is easily accessible. In the present studies, LCD powder and glass powder were used at ratios of 20% and 40%, respectively, relative to the cement weight. Then, 9 mixture designs as cubic specimens were made (with 3 iterations for each design). Subsequently, the prepared specimens underwent different tests including compressive strength, tensile strength, flexural strength, capillary water absorption, and slump tests. The obtained results indicated that glass powder, due to the high silicon content, increased the temperature in the cement hydration process and caused the melting of the LCD particles. The compressive strength and flexural strength of concrete increased with the increase in the glass content and were maximized in the specimens in which glass powder and LCD powder were used equally at ratios of 20%. However, with further increase in the glass content, due to the increased amount of crystalline matter, reduced cement content, and increased porosity of the concrete matrix, all three strength types (i.e. compressive, flexural, and tensile) were reduced. In terms of capillary water permeability, the maximum durability was obtained in the 20%-20% mixture design, which yielded the best performance and the lowest permeability. Furthermore, the concrete slump was increased with increasing the content of LCD and glass powder. This can be attributed to the phase change of LCD, which increased the composite's viscosity by being melted in the concrete matrix and, besides, increased the concrete's efficiency. According to the obtained results, it is recommended to investigate the microstructure and simulation of concrete, under-pressure permeability test, electrical resistance test, and melting and solidification cycles
