EVALUATION OF THE PROPERTIES OF METAKAOLIN BASED GEOPOLYMER CONCRETE MADE WITH RECYCLED CONCRETE AGGREGATE

📄 Project Abstract

Over the years, the construction industry consumes large amount of materials and produces waste in large quanties, this practice depletes natural resources like aggregates and causes problem of waste accumulation. In order to attain sustainability, emphasis is made on circular pattern of consumption as against the linear pattern of consumption. Recycled Concrete Aggregate (RCA) is an example of waste produced from construction and demolition activities. Efforts have been made to eliminate the problem associated with cement usage and its production by fully replacing cement with an environmentally friendly binder known as geopolymer. Many researchers utilized natural aggregates in the production of geopolymer concrete but few researches have been carried out producing geopolymer concrete using RCA. This research evaluates the properties of metakaolin based Geopolymer Concrete (GPC) containing RCA. Metakaolin and alkaline solution (sodium hydroxide and sodium silicate) is the binder used...
