Abstract
Abstract: Concrete demand has increased to satisfy the need of infrastructural development facilities. Tremendous amount of natural resources and energy is consumed for production of ordinary Portland cement. It also emits substantial quantity of carbon dioxide into the atmosphere. Therefore, it has been need of the hour to find out alternatives for making eco-friendly concrete. Many siliceous and alumnio-siliceous material are available which possess little or no binding values. But these materials in finely divided forms when come in contact with moisture, they chemically react with calcium hydroxide to form compounds those have binding properties. In the current studies when research was conducted on pozzocrete in laboratory it was well established that when pozzocrete is used in concrete, it increases the strength of concrete. Pozzocrete being finer than cement, gives more specific surface, fills the voids, increases workability of concrete and also reduces the problem of shrinkage in concrete. In the current study, the behavior of pozzocrete with cement concrete is reported. Percentage variation of pozzocrete in cement concrete to replace cement is tested to achieve economy as well as higher strength of RCC structural members. An experimental investigation was carried out on pozzocrete in reinforced cement concrete. Weigh batching method was used for 10% to 30% replacement of cement by pozzocrete in M20 grade concrete. It was found out that 30% replacement of cement with pozzocrete gave most acceptable results in flexural behavior. Workability and ductility of concrete was also found to be increased with increase in flexural strength.
