Abstract Cement is the most significant component in concrete. Large-scale manufacturing of cement consumes more energy and releases harmful products (carbon dioxide) into the atmosphere, adversely affecting the environment and depleting natural resources. A lot of research is going on globally, concentrating on the recycling and reuse of waste materials from many industries. A significant share of research is focused on finding cementitious materials alternatives to ordinary Portland cement. Many industrial waste by-products, such as quartz powder, metakaolin, ground granulated blast furnace slag, silica fume, and fly ash, are under investigation for replacement of cement in concrete to minimize greenhouse gases and improve the sustainable construction. In this research, the effect of a new material, i.e., alccofine as a partial replacement (i.e., 0%, 5%, 10%, and 15%) and constant fly ash dosage (i.e., 25%) on thermogravimetric analysis, X-ray diffraction analysis, Fourier transform infrared spectroscopy, scanning electronic microscopy analysis on concrete were studied. Adding alccofine and fly ash showed a significant improvement on the analytical methods of self-compacting concrete.

Introduction The self-compact concrete (SCC) is classified as a new material in which the concrete gets compacted under its selfweight without main contributions from mechanical vibrator. The self-compact concrete is very useful to fill the spaces in case of for heavy structural elements such as beams, slabs, columns, shear walls, and foundations. Many advantages for self-compact concrete make the structural engineering to adapt such as reduction in time of constructions, no noise, improving the capacity of the structural elements by filling the spacing’s and giving excellent structural behavior. * Bode Venkata Kavyateja [email protected] J.

Superplasticizer can be used in concrete mix to avoid segregations and increase the concrete workability [1]. Ordinary Portland cement (OPC) is one of the most commonly used building materials globally. The Portland cement production process consumes a significant amount of heat energy and releases a huge amount of carbon dioxide ( CO2) into the atmosphere which further has severe environmental effects. Portland cement production has been reported to be liable for about 3% and 9% of worldwide energy consumption and
