Abstract
Urbanization growth rate in India is very high due to industrialization. For large construction, concrete is preferred as it has longer life, low maintenance cost and better performance.Ordinary Portland cement is the most common type of cement in general use around world because of its high compressive strength .The arecanut is the seed of the areca palm and extensively cultivated in India. According to an estimate India produces about 3000 million tons of husk waste annually.In this project the recycling of arecanut husk ash as supplementary cementitious material in respect of recycled aggregate concrete. The mixes are prepared with 5 percent intervals (0, 5, 10, 15 and 20) of arecanut husk ash as a partial replacement of Portland cement. Concrete cubes are tested for compressive strength upto the age of 28 days. Test results have shown that arecanut husk ash is an effective pozzolanic material which gives the better result at the optimal replacement ratio of 10%.
