Hydration Study Of Rice Straw Ash Admixtured Cement Using Ftir And Sem

Abstract:Rice straw ash is used as a mineral admixture to cement in the present study. Rice straw is collected from local paddy field and burnt in a clay pit . The ash was collected and grounded to a fine powder. The grounded ash was sieved using a 75 µm test sieve and replaced partially with cement at 5%, 10%, 15% and 20% by weight. The admixtured samples were hydrated for 1hour to 4 weeks and FTIR , SEM, and compressive strength analysis were carried out. The results were analyzed in the light of available literature.
