Study on producing light weight concrete with foam glass granules

Abstract

In the world, waste glass is widely recycled, especially in developed countries with a recycling rate of about 30-90%. Currently, in Vietnam glass emissions in urban areas account for 1.5-2% of solid wastes; however, few studies mention this waste. Therefore, light weight concrete (LWC) using foam glass granulates (FGG) is the object of this paper. In the study, the raw materials are FGG, But Son PC40 cement, Pha Lai fly ash and Sikament superplasticizer named R4. The experimental results show that with FGG content of 50% (by volume), the LWC’s bulk specific gravity is 1302 kg/m3 and compressive strength at 28 days is 89 kG/cm2. Keywords: waste glass; foam glass granulate; light weight concrete.
