Strength and Durability study on Steel Fibers Reinforced Self Compacting Concrete incorporating Sugarcane Bagasse Ash

Abstract

The present era is "THE ERA OF CONCRETE" because concrete is the most consumed material after water in developing countries. The huge demand of concrete requires large amount of cement which is the basic necessity for strength development of concrete. Large consumption of cement forces very high production to satisfy the demand. But production of cement produces CO 2 in the atmosphere. One ton of cement produces about one ton of CO 2 and hence it creates disturbance in natural global system. So, there is need of alternative materials which can replace cement. Previous researches shows number of materials such as Fly Ash, Silica Fume, Sugarcane Bagasse Ash etc may be used as a replacement of cement. India is second largest country which produces Sugar and hence sugar waste is also produced in very large quantity. Previous researches shows that Sugarcane Ash may be replaced by cement upto certain percentages. The higher percentage may lead to the brittle failure of Concrete which has been prevented by the addition of Steel Fibers. Good range Super plasticizer is used to get Self Compacting nature of Concrete. In the present experimental work we have tried to replace cement by Sugarcane Bagasse Ash. Also the steel fibers have been used to enhance the properties of concrete using Sugarcane Bagasse Ash. Fresh properties like Workability and Hardened properties like Compressive strength, Split tensile strength, Flexural strength and Durability have been carried out. The percentage replacement of Sugarcane Bagasse Ash are 4%, 8%, 12%, 16% and 20% by weight of cement. The addition of steel fibers was 0.50% and 1% by volume of concrete. Comparative analysis of Fresh and Hardened properties of normal concrete and concrete using replacement of Bagasse Ash along with Steel Fibers has been carried out, which shows that initially the replacement of Bagasse Ash alone increases the strength and durability. The highest increment got is at 12% of replacement and the difference in strength is 11.8%. The addition of 1% steel fibers along with Bagasse Ash also increases the compressive strength upto 18%. The split tensile strength and flexural strength are also improved upto 42% and 89% respectively as compared to normal concrete. The results show that there is good scope of work to use Sugarcane Bagasse Ash in concrete industries.
