Experimental investigation an attempt has been made to find the suitability of the fluorescent tube light wastes as a possible substitute for conventional fine aggregate. In a district about40-60% of the fluorescent tube light are wasted due to various reasons. These wastes are not recycled at present. By utilizing this fluorescent tube light waste as a fine aggregate, safe disposal of waste materials can be achieved and construction costs are reduced. This investigation was carried out to evaluate the strength and durability properties ofM25 grade concrete with control specimen 10%, 20%, 30% replacement of fine aggregate with fluorescent tube light waste. Among the strength properties, compressive strength, split tensile strength and flexural strength were conducted. Under the durability properties porosity, acid attack, alkali attack and fire resistance test were conducted..
Geographical Information technology (GIS) is being widely used for the assessment of natural resources. This paper deals with the usage of SWAT as a modelling tool with the integration of ARCGIS for the estimation of surface runoff on a watershed basis. Spatial maps such as elevation information (SRTM data of 90M resolution), soil and land use is used to setup the model. An extensive effort will made in setting up a Indian climate database which consists of numeral climate records containing good quality data. The Soil Conservation Services (SCS) method has been used to assess the surface runoff from the watershed basin
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
