This serves to reduce the consumption of large amounts of natural resources and contribute to the benefit of the economy and environment. However, it is recommended by some studies that up to 10% replacement levels of low-grade and uneconomic glass fines can be used to substitute natural sand in concrete. Although the inclusion of waste glass sand might lead to an increase in cost, it serves as an eco-friendly option that obtains acceptable concrete characteristics and a reduced cost of waste management. Also, since ASR reactions are attributed to various parameters, including particle size, well-graded glass send can serve to increase the density due to the micro-filling effect and thus lower the risk of ASR expansion. Studies show that using waste glass sand up to 20% replacement levels did not show substantial ASR expansion. The authors recommended the usage of 50% WGS as the optimum replacement percentage for low-cost, high-strength concrete.įrom the main concerns that lie behind the use of waste glass sand in concrete is the Alkali-Silica Reaction (ASR), which occurs between amorphous silica present in the glass composition and alkali in cement, resulting in excessive expansion when moisture is present and thus affects the durability of concrete. Also, it was concluded that the presence of WGS in concrete mixes reduced the production cost by up to 30% for a 75% replacement level. In terms of concrete mechanical properties, it was shown that the elasticity modulus, compressive strength, split tensile strength, and flexure strength for a concrete mix with 50% WGS as FA replacement was increased by 7%, 27%, 9%, and 50%, respectively. Results showed that the workability of concrete enhanced as the percentage of WGS increased. In addition, the cost of each mix was calculated to evaluate the cost reduction efficiency of concrete with WGS compared to normal concrete. For each mix, cubic, cylindrical, and beam specimens were cast to study the workability and different mechanical properties of concrete-like density, elasticity modulus, compressive strength, ultrasonic pulse velocity (UPV), split tensile strength, and flexural strength. Four concrete mixes were considered in this study with varying percentages of WGS (0%, 25%, 50%, and 75%). This paper investigates the production of low-cost, high-strength concrete by partially replacing fine aggregates (FA) with waste glass sand (WGS). One of these materials is high-strength concrete. New technologies are needed to reduce the cost of producing these materials and to ensure better efficiency when the materials are used in various engineering projects. When a material bends you need to use the flexural modulus ( Ef) as the material property for your stress and deflection calculations and this is why it is of very high importance to measure the flexural modulus of your material / component.The world of building materials is constantly and rapidly developing. Important: Many engineers use the Young's modulus (often referred to as E) as the material property of choice for all types of stress calculations (σ = E*ε).
