| Abstract | ||
| This study deals with a comparative experimental investigation study on the clays industrial wastes as recyclable materials in blended cement production. In spite of the fact that waste of fired clay bricks (WFCBs), ground or broken bricks, waste of ceramic tiles (WCTs), and waste of vitrified clay pipes (WVCPs) are silicates solid waste, their management recycling has the best environmental, social, and economic aspects. The implementation of these wastes as recyclable materials in wall materials, mortar, and concrete was used as raw materials or cement additives as pozzolanic materials for rapid urbanization and improvement of construction and high pollution rates in the developing countries such as Egypt. A large amounts of these wastes has been produced from factories for producing clay bricks, ceramic tiles, and vitrified clay pipes, as well as construction operations, building improvement, and the demolition of old buildings. The mortar microscopic structures were observed by scanning electronic microscope (SEM), while hydration minerals were studied using X-Ray Diffraction (XRD) as well as differential thermal analysis (DTA).These wastes, as artificial pozzolanic materials, rise the setting time of cement products. The average strength of compressive and flexural accelerates at early age slower than later age. The study aimed to reduce construction solid waste and conserve raw material resources. These wastes are widespread in the Egyptian provinces, and there is very a little available information on their chemical composition and mineral components | ||
