Waste Glass Powder as Partial Replacement of FA for Sustainable Paver Blocks Hashim Yousuf and C. S. Bindu 1 Introduction The concrete industry has steadily developed in the last 50 years, and right now the current challenge is to make concrete in the most sustainable manner while using resources optimally. This problem has come to the fore as many studies have pointed out that extensive dredging of river beds has led to severe ecosystem damages and serious long-term environmental impacts [1, 2]. This has led to a shortage of sand for construction recently [3, 4]. Compounding the problem is the fact that the rate of consumption is also expected to double [5]. Researchers have been searching for suitable alternatives that could be used, and glass wastes have shown promise. Their main advantages include their inertness like sand and our ability to adjust its fineness properties. Even though it shows promise, it is also a challenge as they are not easily available at all places. If we were to transport the waste glass powder to the required sites, it could offset the environmental gains we have strived for. In addition, quality control would become an issue when using a new material at a site directly. A solution to this would be to use it to create a product that meets the required criteria in strength and durability and then to use this product in construction. Early studies into the effects of using glass powder in concrete primarily focussed on coarse aggregate replacement. However, the results from these experiments indi- cated that the presence of these larger glass particles caused excessive expansion and cracking in the concrete specimens. This resulted in compromised compressive strength. These effects on the specimens could be attributed to the strong reaction H. Yousuf (B ) · C. S.
