EXPERIMENTAL INVESTIGATION OF MECHANICAL PROPERTIES OF FLY ASH BASED GEO-POLYMER CONCRETE USED AS PAVER BLOCKS

The main objective of the present study is to find out a suitable, effective and alternative material for partial replacement of cement and fine aggregate, to find out possible utilization of waste materials in construction industry that in turn considerably minimize the usage of cement and coarse aggregate and ultimately reduce construction cost, to explore possibilities of improving mechanical properties of concrete using copper slag & pond ash instead of fine aggregate partially, to evaluate the effect of using fly ash and GGBS in concrete and to investigate the strength of replaced concrete with that of conventional concrete. This project is mainly undertaken to study the behavior and performance of concrete using waste materials such as fly ash and GGBS. This type of use of a waste material can solve problems of lack of aggregate in various construction sites and reduce environmental problems related to sand mining and waste disposal. The use of fly ash and GGBS can also reduce the cost of the concrete production and increase the workability.
