Nagalooti Waste stone aggregates, Natural aggregate, concrete and flyash.Abstract
Concrete production by replacing conventional CA and FA with crushed waste Nagalooty stone as CA and FA (Other than granite – OTG) and also replacing cement with fly ash up to 30% in traditional concrete of M25 grade in 20 combinations of mix proportions in different percentages. The main aim and objective behind the research is to reduce the production cost of cement concrete and also to clear landfills by utilizing abundantly available waste stones in Nagalooty in Nandikotkur near Kurnool and also to reduce sand usage in concrete keeping in view of ground water table and environmental conditions. For finding the fresh properties, slump cone test was carried and for finding hardened properties, Compressive strength test was conducted to determine the cube compressive strength. In this experiment natural aggregates are replaced by Nagalooti waste stone aggregates in proportion of 0,25,50,75,100% and also cement is replaced with flyash by 0,10,20,30%.
