The experimental analysis has been carried out for evaluating various properties such as workability, compressive and split tensile strength of concrete was carried out using molasses as admixtures. Based on the literature, the main function of using molasses is making concrete compatible, extending the initial setting time and final setting time of concrete. From the result, it was observed that all the properties of concrete were influenced by addition of this molasses in concrete and it is also found that the molases also serve as a water reducing agent. Keywords: Molasses, Concrete, Compressive strength, Workability. 1. INTRODUCTION The use of waste products has become trending for the development of new technologies. It not only reduces environmental pollution but also ensures efficient use in various sectors. Molasses is a by-product of the sugar industry, which has its main component as sugar, which is taken as admixture in this study. There are nearly 571 sugar factories in India. Every industry produces molasses as a by-product. Therefore, its use in the construction industry proves efficient use of the by-product. The dark brown syrup obtained at the end of the refining process is called molasses. Molasses contains approximately 50% sarcose, 30% other sugars (ash and nitrous) and 20% water. Molasses acts as a water-reducing admixture, water cement ratio can be reduced by adding molasses. Molasses has air-entraining property, thus improving the durability of concrete by dispersing the particles in concrete, thus improving the durability of concrete during freezing and thawing. 2. OBJECTIVE To conduct consistency, initial and final setting time test with optimum dosage of superplasticizer with molasses and to estimate extension in setting time. To conduct the marsh cone test with conventional superplasticizer with molasses, workability of concrete was measured. To determine the compressive and split tensile strength of concrete using molasses as admixture. 3. LITERATURE SUMMARY The aim of the investigation was to study the effect of molasses of various properties of concrete containing molasses as an admixture. 3.1. Collection of Sample The sample is collected form co-operative sugar industry located near Rajahmundry. 3.2. Analysis of Sample The sample of molasses, which is obtained from sugar industry, is analysed to determine the chemical composition using EDAX analysis. Figure 1. SEM Image of molecules Figure 2. Concentration of chemicals After analyzing this sample the following chemical composition have been obtained from EDAX analysis.
