Abstract – Now a day’s, major challenges for our
community is the protection of the environment from waste materials .In India alone sugarcane waste accord approx 810 million tones. A good solution would be the utilization of excess sugarcane molasses waste together in the final quality of concrete because it has strong potential .The use of molasses from sugarcane factory in structural concrete as alternative of chemical admixtures (water reduction admixtures). Many research papers on use of molasses has been carried out last few years. The objective of this paper is to determine the effects of structural concrete by adding of sugarcane molasses based on strength, durability, stability and economic aspects. The effects of different dosage level like 0.1, 0.2, 0.3, 0.4, 0.5, 0.6% of the molasses by weight of the cement were analyzed for the consistency, setting time, water reduction and workability. The test were performed for workability and compressive strength by adding dosage level like from 0.1% to 0.6% respectively of the molasses by weight of cement of the design mix M20, M30 and M35 for 3 day, 7 day and 28 day. The test results stipulate that molasses behave like as accelerators up to 0.5 % of dose and after that retarder. The compressive and split tensile strength of structural concrete for 3 day and 7 day with molasses indicates decline in strength. The compressive strength of structural concrete and mortar gets increased by adding 0.5 % of molasses by weight of cement for 28 day. Most favorable dosage level is 0.3 % of the molasses by weight of cement. Key Words: Sugarcane, Molasses, Admixture for concrete, Compressive Strength, Slump, Workability.
Molasses has been used in numerous industries as raw material like animal food industry in the production of alcohol, ferment and glycerine. Approximately, in Maharashtra 173 cooperative sugar factories is in operation which is used for the production of sugar. Adverse impact on environment comes into picture after disposing of waste materials. Thus many researchers has used the waste materials for various purposes. Therefore, sugarcane molasses has been used like a water reducing admixtures [2]. It also makes the concrete economical instead of other admixtures but it will increase the compressive strength. Finally it will be improved the strength, durability, stability, workability and the quality of the concrete.
2. MATERIALS 2.1 Cement 43 Grade Ordinary Portland Cement (OPC) used with trade name of Ultratech Cement conforming to IS: 12269 – 1987[3] having Specific gravity- 3.15 has been used.
2.2 Fine Aggregates Fine aggregates have been taken from local sources. Its specific gravity is 2.69 had taken. Aggregates most of which passes through 4.75 mm IS sieve had used. Sand conforms of IS 383-1970 [4]. Table-1 shows the property of fine aggregates.
1. INTRODUCTION
Table-1: Property of Fine Aggregate
Structural concrete is most widely used material worldwide in civil engineering. It can be cast into any desired shape due to its properties, it has not only replaced the old construction like stone masonry and brick masonry but also can cast complex structures. By addition of admixtures can enhance the quality of concrete and the same time saving of the other constructional materials and make the concrete economical [1]. In situ, structural concrete production requires more skilled or experienced person for their proportioning, addition of chemicals, mixing, placing, compacting, finishing and other operations.
