Study of pore structure effect on durability and strength of concrete incorporating of ceramic waste

Abstract

Concrete is not a new material and has been used for several thousands of years (1). Concrete is second largest material after water used by human beings. In current era, there is lot of innovations happening in the field of concrete technology. The Burj Khalifa one of the world s tallest structure is the example of new innovations (2). As per data from intermit website total sales of concrete and cement in 2013 was 489 billion USD and increased to 664 billion USD in 2016 (3). Annual global production of concrete is about 25 billion tones as per the cement sustainability Initiative (World Business Council). The worldwide market size of ready-mix concrete was estimated at USD 492.2 billion (4). More than 1 m3 of concrete is prepared for each individual on earth. Production of cement produces CO2. There are two ways to reduce production of CO2 either by 100 percent replacement or partially replacement with some pozzolonic materials like fly ash, silica fume, ground granulated furnace slag, Quarry Dust, Rice husk ash, alcofine, glass powder, ceramic waste etc (5-80). CSW is used because Around 12 billion m2 ceramic tiles produced globally. The ceramic powder generated due to final polishing process at the rate of 19 kg/m2. Around 22 Billion tons of ceramic powder globally generates. newlineMain aim of study is to utilize Ceramic sludge waste in concrete as partial replacement of cement and understand microstructure of concrete with CSW. newlineStructures are very important for human beings. Strong and durable structure must be necessary for healthy environment. Some of the raw material for making concrete creates environmental hazards during their production. The manufacturing of cement generates CO2 among all the components used to make concrete. This adds nearly 5-7% of worldwide emissions of anthropogenic carbon dioxide. To overcome this problem, the effort has been made in this research to reduce use of cement. Amongst all the industrial solid waste in this research ceramic sludge waste is used as partial replacement of ce
