“…A significant enhancement was observed in mechanical behavior of modified reactive powder concrete containing 15 % waste pozzolanic material [23]. Cao et al [24] showed that the workability, compressive strength and durability indicators improved with the increased of glass powder content in concrete. Moreover, the results revealed that the presence of waste glass powder has a great effect on the flowability and flowability retention time when were used with especial superplasticizer [25].…”

Environmental protection approach has caused to ignore the conditions and the possibility of using solid waste as a substitute for concrete. In this research, the effect of glass powder in percentages of 0-30 (in steps of 7.5%) and micro-silica (10% as a constant) as a substitute for cement is investigated on efficiency, compressive strength, tensile strength, and bending strength. surface water absorption, capillary water absorption, and freeze/thaw cycle are paid. The results showed that the use of glass powder leads to increases the fluidity and properties of fresh concrete. The mechanical parameters decrease slightly when 30% of cement is replaced with glass powder.

“…and Soliman and Tagnit-Hamou 14 found that the weak bonding between glass sand and the cementitious material, as well as the flat shape of the glass sand, would decrease the mechanical performance of concrete. Many studies have also shown that the water absorption rate of concrete with added glass sand will increase 9,15 , and the resistance to chloride ion erosion will deteriorate ( [16][17][18][19] ), leading to a decrease in the durability performance of concrete.…”

To investigate the response of concrete's mechanical and durability properties to different particle sizes of waste glass materials, two stages of experiments were conducted. First, comprehensive tests were carried out to separately study the effects of monodisperse glass sand and glass powder on the mechanical and durability properties of concrete. Secondly, based on the results of the comprehensive tests, orthogonal tests were designed to explore the response of composite particle sizes of glass sand and glass powder to the mechanical and durability properties of concrete, and the optimal replacement quantities were obtained. Finally, the influence mechanism of composite particle-sized glass sand and glass powder on concrete properties was revealed through scanning electron microscopy (SEM). The research results show that under monodisperse glass sand/glass powder particle sizes: the incorporation of an appropriate amount of glass sand can enhance the mechanical and durability properties of concrete, but excessive replacement and larger particle sizes can have adverse effects on the properties of concrete; due to the pozzolanic effect of glass powder, the incorporation of glass powder can improve the mechanical and durability properties of concrete, but excessive replacement quantities are not conducive to the development of early strength of concrete, and it is recommended that the replacement rate be controlled within 20%. Compared to monodisperse replacement with a single particle size, under the conditions of compounding addition, the compressive, tensile, and shear strengths of concrete were increased, with improvement magnitudes of 35.56%, 21.74%, and 13.79%, respectively. In addition, the durability of concrete was significantly enhanced, with the maximum reduction in water absorption rate being 20.73%, and the maximum decrease in chloride ion permeation being 63.10%. Under the condition of a total replacement rate of 20%, the optimal relative replacement quantities determined by orthogonal test, range analysis, and response surface methodology were 2.86% of 0.6mm glass sand, 1.43% of 1.18mm glass sand, 8.57% of 50-60μm glass powder, and 7.14% of 60-70μm glass powder. The incorporation of composite particle-sized glass sand and glass powder played a role similar to gradation in the concrete matrix, improving the microstructure of concrete, thereby enhancing the mechanical and durability properties of concrete.
