Eco-efficient self-compacting concrete with silica sand waste

Recently, researchers and technologists have been focusing their efforts on the development of environmental-friendly construction materials with particular attention on the utilisation of industrial waste materials in their manufacture for sustainable development. The aim of these works is a study focused on the potential use of sand waste generated by the industrial manufacturing of zeolites in the production of SCC, so affecting the consumption of natural raw materials, water, and energy. The solid waste has been characterized by analytical techniques such as X-Ray, EDAX, and SEM, before its use in concrete production. Fresh and hardened properties of SCC have been determined. The results pointed out that waste sand can potentially used as a complementary material in SCC production
