Evaluation of Some Industrial Solid Wastes in the Production of Blended Cement

Abstract

Utilization of pozzolanic materials for production of different types of blended cement becomes one of the most important goal in the field of construction and building materials. Pozzolanic materials produces blended cement with higher chemical resistance to sulphate and chlorides attack, lower heat of hydration and improved mechanical and fire resistance properties. Nowadays, using pozzolanic cement is increasing worldwide because it need less energy and decrease the emission of carbon dioxide gas which emitted during cement production. Ceramic waste (CW) is a by-product and Non-recyclable waste generated by stone wares ceramic such as the wall, floor tiles and sanitary ware. It consists of about 66% of silica with high surface area. These characteristics account for the pozzolanic activity of ceramic waste. Nanotechnology is the base technology of an industrial revolution in the first of 21 century, nanoparticles were found to have numerous applications in various fields. One of these important fields is using nanoparticles in construction materials. Carbon nanotubes (CNTs) is the most important nanoparticles nowadays. Carbon nano-tubes, usually used to enhance the microstructure, mechanical properties and fire resistance of blended cement. This investigation is divided into four parts: Part A Part A aims to study the physicochemical and mechanical characteristics of some artificial pozzolanic cement pastes containing ceramic waste (CW). Different OPC - CW blends were prepared by partial replacement of OPC by 5,
