Abstract

(An experimental study on durability of concrete with recycled glasses (fine) and silica fume)
Abstract
Recently, there has been an increasing trend toward the use of sustainable materials. Sustainability helps the environment by reducing the consumption of non-renewable natural resources. Concrete – the second most consumed material in the world after water – uses a significant amount of non-renewable resources. As a result, an experimental investigation was conducted to study the durability of concrete constructed with 5% and 10% recycled glass aggregate (fine) as well as 6% silica fume. This experimental program consisted of six mix designs. The electrical resistivity and chloride ion penetration of recycled concrete mixes were compared with the conventional concrete. Results of this study show that the mixes including both recycled glass aggregate and silica fume show superior durability (both electrical resistivity and chloride ion penetration) compared with conventional concrete.
