COMPARATIVE ANALYSIS OF DESIGN PRECAST CONCRETE PAVEMENT BLOCKS BY USING INDUSTRIAL SOLID WASTES

This paper aims to Industrial solid wastes material used in Precast Concrete Pavement, because of day-by-day increasing industrial solid wastes and its direct attack to the global warming and environmental disastrous have become major issue start from 2015. In this research under the partial replacement of cement, coarse and fine aggregate by fly ash, steel slag and stone dust. Extensive research has clearly established, the Industrial waste such as fly ash used in Precast Concrete Pavement as replacement of cement, steel slag used as replacement of course Aggregate and stone dust as a replacement of fine aggregate. The results indicate that for conventional Precast Concrete Pavement, the partial replacement of cement, coarse and fine aggregate by fly ash, steel slag and stone dust improve the compressive, tensile and flexural strength. By using the mix design of M25, M30, M40 grade with replacement of fly ash as cement 15%, steel slag as coarse aggregate and stone dust as fine aggregate in different percentage (%) of replacement of steel slag and stone dust (40%, 50%, 60% and 100%) has a significant effect in increasing the strength and leads to economical construction of Precast Concrete Pavement. The use of such Pavement improves the time required for repairing and construction of highways. Also, minimize the industrial solid waste, so that it is economical and good for environment.
