- Abstract
The amount of waste material has increased with the development of the standard of life, and with an increase in the population, for that waste material treatment and the recycling process are two of the main subjects of research and study trends in many countries around the world. There are many kinds of waste materials, including different types of glass waste. The idea of reusing waste material in the building application has a successful past, such as in mortar. Mortar is one of the construction industry's most used and economical materials, so studying its composition and properties is essential. In this study, sand has been replaced by the weight of glass with 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50%, using two different types of glass (white and green glass); as a result, with an increase in replacement ratio up to 10% of sand replacement in both the glass types, flowability increased while with continuous increase in replacement ratio, the flowability decreased. Compressive strength increased by 3.26% after 28 days when 20% of the sand was replaced by white glass, while it increased by 9.25% after 28 days when 10% of the sand was replaced by green glass. Flexural strength increased by 27.88% after 28 days when 15% of the sand was replaced by white glass. At the same time, it increased by 77.4% at 28 days, when 10% of the sand was replaced by green glass. The optimum obtained results are backed by X-ray diffraction and scanning electron microscopy; afterwards, shear bond strength samples were prepared and tested, and the results demonstrated that shear bond strength shows similar results to that obtained from compressive strength; when 10% of the green glass has been used as the sand replacement, the shear bond strength was 4.7% higher than the obtained value in the control mix; also when 20% of white glass has been used as a sand replacement, the results from shear bond strength were 15.2% higher than the obtained value in the control mix.
